London, May 11, 2017: Big cat species, especially African lion and Sunda clouded leopard, face the same challenges as their ancestors that went extinct towards the end of the last Ice Age, a new study says.

The team researched the cause of extinction of seven large cats from the Ice Age including four different types of sabre-toothed cats.

The seven big cats that went extinct during that period are those which lost the greatest proportion of their prey, showed the study published in the journal Ecography.

Using a new global database of felid diets called FelidDiet, the researchers assessed whether Ice Age extinction trends could be applied to populations of big cat species now.

They discovered that if all the currently threatened and declining prey species within big cat natural ranges were to go extinct, only 39 percent of the African lion’s prey and 37 percent of Sunda clouded leopard’s would remain.

The researchers believe that if this prey loss trend continued, this would pose a high risk of extinction to these two big cat species in particular.

Prey decline puts tiger, leopard and cheetah at risk too, the researchers said.

“If primary big cat prey continues to decline at such a rate, then big cats, including lion, Sunda clouded leopard, tiger and cheetah, are at high risk of extinction,” said Chris Sandom from the University of Sussex in Britain.

“The Churchillian aphorism that those that fail to learn from history are doomed to repeat it was painfully in mind when we saw how many of the prey of lions and in East Africa and of clouded leopards in Indo-Malaya look set to go down the same drain which their counterparts in other regions have already been flushed,” said Professor David Macdonald, Director of the University of Oxford’s Wildlife Conservation Research Unit.

“We need to buck this Ice Age trend once and for all and to reinforce the urgent need for governments to protect both big cat species and their prey,” Sandom added. (IANS)

Study Shows Autistic Traits Behind Revolution in Ice Age Art

The ability to focus on detail, a common trait among people with autism, allowed realistic art to flourish 30,000 years ago during the ice age, according to researchers. Ice age ancestors have created exceptionally realistic art including the extremely accurate depictions of bears, bison, horses, and lions.

While many have argued that psychotropic drugs were behind the detailed illustrations, the new study argued instead that individuals with “detail focus” — a trait linked to autism, kicked off an artistic movement that led to the proliferation of realistic cave drawings across Europe.

“Detail focus is what determines whether you can draw realistically; you need it in order to be a talented realistic artist. This trait is found very commonly in people with autism and rarely occurs in people without it,” said lead author Penny Spikins from Britain’s University of York.

“We looked at the evidence from studies attempting to identify a link between artistic talent and drug use and found that drugs can only serve to disinhibit individuals with a pre-existing ability. The idea that people with a high degree of detail focus, many of which may have had autism, set a trend for extreme realism in ice age art is a more convincing explanation,” Spikins added.

The research adds to a growing body of evidence that people with autistic traits played an important role in human evolution.

“Individuals with this trait — both those who would be diagnosed with autism in the modern day and those that wouldn’t — likely played an important part in human evolution and survival as we colonized Europe,” Spikins said.

Besides, contributing to early culture, people with the attention to detail would also have had the focus to create complex tools from materials such as bone, rock and wood, the study showed.

“These skills became increasingly important in enabling us to adapt to the harsh environments we encountered in Europe,” Spikins noted. (IANS)
