Social welfare fraud tip-offs to office hit 2,000 every month

 

An average of 2,000 people every month reported a suspected case of welfare fraud to the authorities last year, new figures show.

The news comes as the Social Protection department is preparing a new anti-fraud strategy and is also going ahead with plans to add 20 Gardai to its fraud investigation team of 91 inspectors.
The recruitment of Gardai, who will retain their policing powers, drew widespread criticism of Social Protection Minister Joan Burton when it was announced last October.
But she said the fight against welfare fraud is a priority to safeguard taxpayers’ money and ensure fairness for all.
The secondment of Gardai is a trial scheme and the closing date for applications is next Monday, March 24.
It is expected the gardai will be deployed in Dublin, Dundalk, Letterkenny, Monaghan, Longford, Galway, Cork, Limerick, Navan and Sligo.
The latest statistics from the Department of Social Protection show that it received almost 25,000 anonymous tip-offs about suspected welfare fraud in 2013. This is down from the high point of over 28,000 anonymous reports in 2012 but still up markedly on the 16,000-plus reports received in 2011.
Officials stress that an anonymous tip-off is only the start of an investigation process and nobody is cut off until a clear breach of the welfare rules is established.
“In some cases the reports involve people not breaking any rules – for example, somebody receiving a one-parent family allowance and working a set number of hours as permitted by the rules,” one official said.
The Social Protection department does not want to publicise just how many anonymous tip-offs lead to the detection of welfare cheating.
But officials insist that the anonymous tip-offs are an important part of the battle against welfare fraud.
The department is currently updating its 2011-2013 anti-fraud strategy and a new plan is due for publication shortly.
Attention
The staff at the department’s ‘Special Investigations Unit’ already work closely with the Revenue Commissioners and Gardai.
Officials say they pay particular attention to schemes deemed most likely to be abused and also to sectors where casual work is most prevalent.

Irish customers of our banks have more problems than other countries have

  

Irish customers experience more problems with their banks than any other country in the world, a new research has found.

Irish banking customers, along with those living in Denmark and Spain, reported more incidents with banks per customer than in any of the 42 countries surveyed in a global banking study of more than 32,000 people by accounting giant Ernst & Young (EY).
The Irish were also among the most dissatisfied in the world with how banks resolved their complaints – half of people surveyed said complaints had not been resolved to their satisfaction.
The results come just weeks after the country’s banks were named and shamed by the Financial Services Ombudsman for the first time for their poor handling of customer complaints.
The banks publicly identified by the Financial Services Ombudsman included AIB, Permanent TSB, Ulster Bank, Bank of Ireland, Bank of Scotland and Danske Bank.
The damning findings in this latest research are particularly surprising because they contradict global trends.
On average, the survey found, confidence in the banking industry is on the rise, trust in banks is high and most customers are satisfied enough to recommend their main banking provider.
In Ireland, by contrast, 62pc said confidence had fallen in the past year.
Loan application refusals and charges for making a purchase were the biggest sources of complaints.
Transparency about fees and guidance on how to avoid them was the third most common source of dissatisfaction.
The Irish results were surprising, said EY financial services director Patricia Stack, given that Ireland’s banks have been investing heavily in customer service of late. “Consumer confidence globally has gone up but the results for Ireland are less positive, with confidence and trust levels decreasing the most since 2012,” said Ms Stack.
“Banks have some way to go to improve this – for example, increasing transparency around fees and charges. Additionally, improving how they deal with resolving problems or complaints will be critical if banks are to continue to win confidence and build trust.”
“The high level of customer complaints is a strong signal that banks need to get better at communicating their fees and charges with their customers.
“The good news is that solving a problem or addressing a complaint creates a critical customer interaction, which, if done well, can actually increase a customer’s business,” said Ms Stack.
Customers are increasingly on the move, the survey also found. Globally, half of respondents had opened or closed at least one product in the past year and two fifths planned to in the coming year.
Of the 60pc who were not planning to close or move their accounts, confidence in their provider was not the motivator. Nearly a fifth said it was just too difficult or time-consuming to change.
“Bank customers are not being actively retained; they simply remain with their current provider through inertia and are therefore vulnerable to competitors.
Meanwhile, new types of financial services providers with new technologies and customised services are penetrating the global marketplace and cannot be ignored” said Ms Stack.

Links & reports of stroke-drug related deaths entirely incorrect

     

There has been links between certain stroke medications and deaths.

Medical experts have urged people who take medication for strokes to continue to do so despite revelations that 19 deaths were associated with the drugs.
Some 19 deaths over the past two years were associated with the consumption of two blood-thinning drugs known as Xarelto and Pradaxa, which are used to prevent strokes.
However, the Irish Medicine Board (IMB) has said that all of the people who died had “very serious underlying conditions” and said that none of the deaths were linked to either forms of stroke medication.
It added: “The IMB continually advises that people should not cease taking any medicine without seeking medical advice and would advise anyone who has any concerns to talk to their doctor.”
The reported deaths were said to be three times higher than those linked to the older standard stroke drug, known as Warfarin.
In a statement, the IMB claimed elements of the story published in yesterday’s edition of ‘The Sunday Business Post’ were “entirely incorrect”.
It stated: “Assumptions based on comparing reports received for Warfarin with Pradaxa and Xarelto would be entirely incorrect as it is not comparing like with like. Medicine reporting rates are influenced by many factors, including the age of the medicine (with more reports received for newer medicines), the nature of the medicine and publicity about a medicine.
“Thus the reports of fatalities associated with the use of a medicine are not directly attributable to the usage of that medicine; it’s down to a number of factors including proactive calls for reporting on a medicine; the patients having significant underlying illness and treated with multiple medicines and/or surgery.”
The IMB also defended the 188 reports of suspected adverse reactions associated with the Xarelto and Pradaxa it had received in the past two years.
“Numerical comparisons cannot be made on the basis of reports received for Pradaxa, Xarelto and Warfarin and would be misleading.
“Adverse reaction reporting rates for Warfarin, which is a well-established medicine and has been available for over 50 years, would be expected to be lower than those for the newer drugs, where there is a significant effort to remind and request healthcare professionals and members of the public to report all reactions – including those suspected and expected.”

Honey could be the great antibiotic hope

  

Honey has long been known to have anti-bacterial properties. 

Honey could be the key in the battle against antibiotic resistance, experts have said. As well as being a tasty treat, honey could be used to help fight infections, they said.
Scientists at Salve Regina University in the US said that honey has a combination of weapons to beat infection including hydrogen peroxide, acidity, high sugar concentration and polyphenols – all of which actively kill bacterial cells.
CORBETT HOSPITAL DASH
COMEDIAN Ronnie Corbett was rushed to hospital suffering from chest pains, his wife said.
The 83-year-old underwent tests for several days last week before being discharged in time to attend the memorial of close friend Sir David Frost.
SNAIL VENOM PAINKILLER
EXPERTS are attempting to create a pain relief drug derived from snail venom used to paralyse their prey.
Scientists have reported creating five new “experimental substances” based on a tiny protein found in the venom of a cone snail. The substances, which could potentially be stronger than morphine, could one day lead to the development of a drug to treat chronic nerve pain, the scientists at the University of Queensland, Australiasaid.
MALE MINDS AND SEX
MEN would spend more than four hours having sex and barely three-and-a-half hours working during an “ideal day”, a survey has found.
Research conducted for Unilever Compressed deodorants also found 64pc of men confessed to regularly using their smartphones and tablets while on the toilet – while 26pc planned a to-do list while being intimate with their partner.
$1M FOR A TREEHOUSE
A US man has been told he can keep a treehouse he built for his sons – if he takes out a $1m insurance policy.
Two months after moving into a house in Wenatchee in Washington state, Zeb Postelwait received his first notice from the city to tear it down. Officials reportedly said the treehouse overhangs the public pavement. But Mr Postelwait disagrees and said he would not take out the insurance policy.
FOSSIL FIND AT SUBWAY
SCIENTISTS have long known that years before tourists were trekking Los Angeles’s Miracle Mile, dinosaurs were doing so.
A subway dig at the La Brea Tar Pits has reportedly uncovered a treasure trove of prehistoric artefacts including molluscs, asphalt-saturated sand dollars – and possibly the mouth of a sea lion.

Global sea levels could rise much faster than scientists previously imagined

  

Scientists say that the Greenland ice sheet has contributed more than any other ice mass to sea level rise over the past two decades and has the potential to raise global sea level by more than 7 metres

North-east corner of Greenland ice sheet, excluded from computer simulations predicting sea rise as it was considered ‘stable’, has lost 10 billion tonnes of ice a year since 2003.
Sea levels across the world are set to rise much faster than previously imagined as the Greenland ice sheet, which has been stable up to now, has started to melt.
Regional warming has triggered a sudden and sustained mass loss in Northeast Greenland ice sheet.
Scientists found that the northeast Greenland ice sheet lost about 10 billion tons of ice a year from April 2003 to April 2012.
The Greenland ice sheet is thought to be one of the largest contributors to global sea level rise over the past 20 years, accounting for 0.5 millimetres of the current total of 3.2 millimetres of sea level rise per year.
According to previous measurements and aerial photographs, the northeast Greenland ice sheet margin appeared to be stable for 25 years – until 2003.
Northeast Greenland, where the glacier is found, is of particular interest as numerical model predictions have suggested there is no significant mass loss for this sector, leading to a probable underestimation of future global sealevel rise from the region.
An international team of scientists, including Professor Jonathan Bamber from the University of Bristol, studied the Northeast Greenland Ice Stream which extends more than 600 km into the interior of the ice sheet: much further than any other in Greenland.
Professor Bamber said “The Greenland ice sheet has contributed more than any other ice mass to sea level rise over the past two decades and has the potential, if it were completely melted, to raise global sea level by more than seven metres. About half of the increased contribution of the ice sheet is due to the speed up of glaciers in the south and northwest. Until recently, Northeast Greenland has been relatively stable. This new study shows that is no longer the case”.
The international team of scientists discovered that the last remaining stable portion of the Greenland ice sheet is stable no more.
The new result focuses on ice loss due to a major retreat of an outlet glacier connected to a long river of ice – known as an ice stream – that drains ice from the interior of the ice sheet.
The Zachariae ice stream retreated about 20 kilometers (12.4 miles) over the last decade, the researchers concluded.
For comparison, one of the fastest moving glaciers, the Jakobshavn ice stream in southwest Greenland, has retreated 35 kilometers (21.7 miles) over the last 150 years.
Ice streams drain ice basins, the same way the Amazon River drains the very large Amazon water basin.
“Northeast Greenland is very cold. It used to be considered the last stable part of the Greenland ice sheet,” explained lead investigator Michael Bevis of The Ohio State University. “This study shows that ice loss in the northeast is now accelerating. So, now it seems that all of the margins of the Greenland ice sheet are unstable”.
Study leader Shfaqat Abbas Khan, a senior researcher at the National Space Institute at the Technical University of Denmark, said that the finding is cause for concern.
“The fact that the mass loss of the Greenland ice sheet has generally increased over the last decades is well-known but the increasing contribution from the north-eastern part of the ice sheet is new and very surprising,” Khan said.

Climate change could lead to famines sooner & by the 2030’s

    

Crop yields could be in danger sooner than we thought.

New research suggests that from the 2030′s onwards man-made climate change will significantly reduce crop yield in temperate and tropical regions.
“Our research shows that crop yields will be negatively affected by climate change much earlier than expected,” Professor Andy Challinor, from the School of Earth and Environment at the University of Leeds and lead author of the study, said in a news release. “Furthermore, the impact of climate change on crops will vary both from year-to-year and from place-to-place – with the variability becoming greater as the weather becomes increasingly erratic.”
The researchers created a new data set by looking at 1,700 published assessments on how climate change will affect rice, maize and wheat crops. The team was able to gather the largest-ever dataset on crop responses.
In the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report researchers reported that regions such as Europe and the majority of North America would be able to deal with a few degrees of warming without seeing it affect seasonal harvests. These new findings will be incorporated into the panel’s fifth report set to be published in the near future.
“As more data have become available, we’ve seen a shift in consensus, telling us that the impacts of climate change in temperate regions will happen sooner rather than later,” Professor Challinor said.
The research team concluded the world would see crop consequences after a warming of only two degrees Celsius, or by the 2030s. In the second half of the century decreases of over 25 percent could be even more common.
In some regions farmers have already been forced to adjust their planting dates or crop variety in order to adapt to warming temperatures.
“Climate change means a less predictable harvest, with different countries winning and losing in different years. The overall picture remains negative, and we are now starting to see how research can support adaptation by avoiding the worse impacts,” Professor Challinor said.

40 % of all babies born in Ireland are outside of marriage

 

The Central Statistics Office (CSO) figures show that 36.5% of all births in Ireland were registered outside of marriage, official stats have revealed.

Of those 6,406 births, 3,685 were to parents living together but not married.
The CSO Vital Statistics First Quarter 2013 report showed that the number of babies born in the first quarter of the year was down 9% from the same time in 2012.
The Central Statistics Office (CSO) showed a total 17,563 births were registered in January, February and March – down from 19,313 in the first quarter of last year.
The figures indicated an annual birth rate of 15.3 births per 1,000 people – down from 16.9 in the first quarter of 2012.
Geographically, the highest birth rate was recorded in Fingal, at 19.6 births per 1,000 people, while Donegal had the lowest at 11.4 per 1,000.
The CSO Vital Statistics First Quarter 2013 report also revealed that 36.5% of all births were registered outside of marriage.
More than half the babies born in Limerick City were born to unmarried parents, while Leitrim recorded the lowest portion of babies born outside of marriage.
While fewer births were recorded across Ireland in the first quarter of 2013 compared with the same time last year, the number of deaths increased.
Some 8,347 deaths were registered in the first three months of the year – up 4.6% from the same period in 2012.
The new figures represent a death rate of 7.3 per 1,000 people.

Shocking new figures for Ireland have revealed the scandal of our missing children,

11 KIDS FROM LAST YEAR REMAIN UNTRACED.

  
The latest Garda data shows that 18 children are reported missing every day, that is double the rate a decade ago.
The grim statistics disclose that 207 boys and girls who disappeared since 2003 — many of them foreign-born — officially “remain untraced”.
The force has dealt with a staggering 51,193 reports of missing youngsters aged under 18 during the past ten years.
And while many of them eventually show up, last year’s total of 6,661 was a massive 141 per cent surge compared to 2003.
And a Garda source told how some of the cases under investigation were classed as tugs-of-love involving feuding parents.
He said: “You see more cases in the past few years, especially where men and women from different countries have kids and then separate.
“One might take off to their home country and take the kids without permission and so the other parent reports them missing.”
Cases include the harrowing abduction of Faris Heeney, six, who was smuggled out of the country dressed as a girl.
His distraught mum Norma has urged the Government to intervene after the family was told there was no legal way of forcing the boy’s Egyptian father to return him.
And Michael Doyle, also known as Michael Lyons, was just two when he disappeared from his home in Tullow, Co Carlow in 2004. He is thought to have ended up in the UK.
The trend in recent years reveals more boys than girls are now being reported missing — but female disappearances outnumber males overall by 3,000 between 2003 and 2012.
Campaigners working with immigration and children’s organisations have also raised awareness of kids being trafficked into the underworld sex trade, at home and abroad, with some even suspected of being victims of murder.
And Gardai probing missing foreign kids expressed concern that some who enter the country unaccompanied are taken into care, only to be secretly taken by their parents who are already in the country illegally.
Research found that 12% of all children reported missing were born abroad, and these formed the biggest category of unsolved cases.
Justice Minister Alan Shatter insisted that everything possible was done to solve all the mysterious disappearances.
He stressed: “I am assured by the Garda authorities that all incidents where persons have been reported missing remain under investigation until such time as the person is located.”
He was replying to a parliamentary question from his Fine Gael party colleague, Kildare TD Bernard Durkan.
The garda breakdown was sent to Mr Durkan and showed there was also a major problem with locating missing adults, with the whereabouts of 174 persons unknown. Two in three of the 19,922 cases reported were men — and just over a quarter were foreigners.

Visitors to Ireland numbers up by 7.6%

  

CSO FIGURES SHOW INCREASE OF ONE-FIFTH IN NUMBER OF TOURISTS FROM NORTH AMERICA IN MAY-JULY PERIOD

Surfers on Rossnowlagh beach in Donegal. Today’s figures from the Central Statistics Office show the number of trips to Ireland from overseas increased by 7.6 per cent in the months from May to July.
The number of overseas trips to Ireland increased by 7.6 % in the three months from May to July of this year, with the number of visitors from North America up by more than 20% compared to the same period last year.
Figures published by the Central Statistics Office show a total number of 2,084,600 trips were made to Ireland, up by 146,800 on the 2013 period.
Minister for Tourism Michael Ring said the figures were “very encouraging” and that they again suggested The Gathering initiative was delivering more overseas visitors.
“I would like to thank the thousands of volunteers throughout the country who have organised and helped out with Gathering events and brought a great sense of community and pride back to parishes and towns,” the Minister said.
“Visitors from overseas are enjoying their holiday experience here in Ireland with many promising to return again in the future.”
Trips by North American residents were up by 20.5 per cent to 418,700.
The number of trips by residents of European countries other than Britain was up by 5.1 per cent to 760,400 and trips from other areas were up 11.9 per cent to 134,700.
British visitors to here were up by 3.3 per cent to 770,800.
In total, the number of overseas trips made by Irish residents during the May-July period was up by 3.2 per cent to 1,999,200.
From January to July, the number of trips to Ireland increased by 6 per cent when compared with the same months last year.
Mr Ring said visitors from overseas were enjoying their holiday experience here with many promising to return again in the future.
He also welcomed CSO figures this week which showed an 8 per cent increase in employment in accommodation and food services over the last 12 months.
He said this showed the special 9 per cent tourism VAT rate and other tourism measures were supporting job creation.

Teen drinking among girls increases the chance of breast cancer by 33%

 

study published in the Journal of the National Cancer Institute found that mothers who had drunk around two units of alcohol a day in the decade after their periods began were 34% more likely to develop cancer than those who did not drink during the same period.

The association was strongest among mothers who started their family later in life.
Research has previously found that alcohol is a key factor in breast cancer, with women who drink around two units a day having about a 24 per cent increased risk of the disease.
The new study found that the risk was even more marked if women started drinking younger, with an even stronger association depending on how long they were fertile for before becoming pregnant.
Women who never have children, or delay becoming pregnant, were already known to be more susceptible to breast cancer.
Researchers led by Dr Ying Liu from Washington University School of Medicine in St Louis, US, examined the history of 91,000 women aged 15 to 40,
The evidence suggested that alcohol consumed before first pregnancy may play an important role in the development of breast cancer, said the researchers.
“Reducing alcohol consumption during this period may be an effective prevention strategy,” they concluded.
The findings indicated a dose-dependent relationship, which means the more alcohol a woman drinks during that time, the higher her risk of developing breast cancer.
Dr Liu said: “The general consistency in the patterns of association between alcohol and risk of proliferative benign breast cancer disease and of breast cancer lends support to the hypothesis that alcohol intake, particularly before first pregnancy when breast tissue is likely at its most vulnerable stage, may play an important role in the etiology of breast cancer.”
She added: “These findings have potentially important implications for breast cancer prevention.”
Professor Paul Pharaoh, Professor of Cancer Epidemiology, University of Cambridge, said:
“What we already know is that in a rather general sense drinking alcohol is associated with an increased risk of breast cancer and that the more a woman drinks the greater the risk.
“What we did not know: whether drinking alcohol at different ages has greater or lesser effects. Of particular interest is the time between puberty (menarche) and first pregnancy, when the breast tissue might be particularly susceptible.”
The figures were collected using questionnaires as part of the Nurses’ Health Study II (NHSII).
Alcohol consumption in four age periods were obtained by asking participants about the total number of alcoholic drinks consumed at different ages: 15-17, 18-22, 23-30, and 31-40.
Among these women, 1,609 cases of breast cancer and 970 cases of BBD occurred during the study period.
Previous research has found that women who drink are more likely to develop many sorts of cancers compared with those who are teetotal.
As well as increasing the risk of breast cancer, it also increases the chance of disease of the liver, mouth, throat and oesophagus.
Research has yet to establish why drinking alcohol seems to increase breast cancer risk. Studies have suggested that alcohol can increase oestrogen levels which could trigger hormone-receptor-positive types of the disease.

Scientists discover a massive canyon below Greenland ice sheet

  
Using radar data from NASA’s Operation Ice-Bridge, scientists found a huge canyon that runs from near the centre of Greenland northward to the fjord of the Petermann Glacier.
A canyon at least 750km (460 miles) long with depths of up to 800 metres (2,600 feet) has been lurking 1.6km (1 mile) beneath an ice sheet that blankets Greenland, data from an airborne science mission has revealed.
The canyon has the characteristics of a winding river channel and is longer than the Grand Canyon in Arizona, US space agency NASA said, adding that the canyon is thought to predate the ice sheet that has covered Greenland for the last few million years.
“One might assume that the landscape of the Earth has been fully explored and mapped,” said Jonathan Bamber, professor of physical geography at the University of Bristol in the United Kingdom, and lead author of the study. “Our research shows there’s still a lot left to discover.”
The research has been published in the journal Science.
The scientists mapped out the canyon by using thousands of kilometres of airborne radar data that NASA and researchers from the UK and Germany have collected over several decades.
NASA’s Operation IceBridge collected a large portion of this data between 2009 and 2012.
In their analysis of the radar data, the scientists discovered a continuous bedrock canyon that extends from almost the centre of the island and ends beneath the Petermann Glacier fjord in northern Greenland.
At certain frequencies, radio waves can travel through the ice and bounce off the bedrock underneath. The amount of times the radio waves took to bounce back helped researchers determine the depth of the canyon. The longer it took, the deeper the bedrock feature, NASA said.
The researchers believe the canyon plays an important role in transporting sub-glacial meltwater from the interior of Greenland to the edge of the ice sheet into the ocean. NASA said evidence suggests that before the presence of the ice sheet, as much as 4m years ago, water flowed in the canyon from the interior to the coast and was a major river system.

The shark that walks! New species discovery is a cool sign for conservationists

     
Conservation International’s Mark Erdmann captures this amazing footage of a new species of “walking” shark, which he and other scientists discovered in Indonesia.
Just watching a shark that uses its fins to walk across the ocean floor is cool enough, but the fact that one more “walking” species has been discovered is even cooler for conservationists.
“This is the third walking shark species to be described from eastern Indonesia in the past six years, which highlights our tremendous shark and ray biodiversity,” Indonesia’s foremost shark expert, known by the single name Fahmi, said in a news release from Conservation International. “We now know that six of the nine known walking shark species occur in Indonesian waters, and these animals are diver favorites with excellent potential to help grow our marine tourism industry.”
The latest species of walking shark was first photographed by divers in 2008, and has now been described as a new species in the journal Aqua. It’s known as the epaulette (long-tailed carpet) shark, or Hemiscyllium halmahera. Two specimens were caught by scientists from the Western Australian Museum and Conservation International in Indonesia’s Maluku Islands (also known as the Moluccas or the Spice Islands). The species name refers to Halmahera, the largest island in the Malukus.
Walking sharks uses their pectoral and pelvic fins to move across the sea bottom while foraging at night for small fishes and invertebrates. H. halmahera is distinguished from other walkers by the distinctive pattern of brown spots on its head.
Indonesia is home to at least 218 species of sharks and rays. In a blog post, Conservation International’s Mark Erdmann marveled at how much progress Indonesia has made in protecting its native sharks. “If you asked me a year ago about the long-term future of shark populations in Indonesia, I probably would have responded: ‘Bleak.’”
Indonesia has been the world leader in the export of dried shark fins and other products from the animal group that includes sharks as well as rays and skates, known as elasmobranches. But over the past year, the Indian Ocean country has come to appreciate that the creatures are worth more alive than dead.
“We now know, for instance, that a living manta ray is worth up to $1.9 million to our economy over the course of its lifetime, compared to a value of only $40 to $200 for its meat and gill rakers,” said Agus Dermawan, director of the Marine Conservation Directorate at the Indonesian Ministry of Marine Affairs and Fisheries.
A recent study showed that Indonesia ranks second globally as a manta tourism destination, with an estimated direct economic benefit of more than $15 million to the country’s economy annually.
To preserve marine biodiversity — and keep the tourist dollars coming in — new sanctuaries for sharks and rays are being created. The Indonesian government also has pledged new regulations to comply with the CITES treaty on species protection.
Update for 2:15 p.m. ET Aug. 30: On the “Why Evolution Is True”blog, Matthew Cobb says the shark’s walking style looks a lot like the gait of a typical tetrapod. “So this suggests that the neuronal control of the way that you run (your right arm moves with your left leg, and your left arm moves with your right leg – try it) goes waaaayyyy back even beyond our fishy ancestors, to the time before the evolution of bone,” he writes. “Another alternative is that this is convergent evolution — if you are going to ‘walk,’ the alternate gait is the best way of doing it.  Today’s question: How could we test between these two hypotheses?”
