Raven world’s second smartest creature

Birdbrain is no longer a sign of stupidity; indeed it could be a sign of surprising intelligence. 


Scientists Bernd Heinrich and Thomas Bugnyar reveal a series of experiments that back the idea that ravens are the brainboxes of the natural world. "These birds use logic to solve problems and some of their abilities even surpass those of the great apes."


The experiment they outline involved ravens that were allowed to sit on perches from which pieces of meat dangled from string. To get a treat, a raven had to perform a complex series of actions: pull up some of the string, place a loop on the perch and hold it with a claw, then pull up another section of string and hold that loop on the perch. By repeating the process half a dozen times, a raven could reach the end of the string and get the meat.

Anthropomorphism

Are chimps more evolved?

A comparison of 14,000 human and chimpanzee genes by researchers at the  University of Michigan, U.S, shows that the forces of natural selection have had the greatest impact on our ape cousins. Humans and chimps followed different evolutionary paths from a common ape ancestor about 5 million years ago. Both underwent changes as the fittest survived to pass their genes on to future generations.

But the U.S study shows that the humans possess a "substantially smaller" number of positively-selected genes than chimps. This may be because the original human population was very small-which would have reduced the effectiveness of natural selection. Instead,"genetic drift" -the random survival of genetic mutations rather than their preservation by the laws of natural selection -was likely to have been more important for humans.

"These observations refute the anthropocentric view that a grand enhancement in Darwinian selection underlies human origins." scientists wrote in the Journal Proceedings of the National Academy of Sciences.

The Cockatoos Story

A picture story sent in by a friend was so moving I thought we must have a blog topic exclusively for "anthromorphism". Anthropomorphism, also called personification, is the attribution of human characteristics and qualities to nonhuman beings.

Scientists at one time used to look down upon such stories-as figments of human imagination. But as human beings are observing and flming more deeply into the private lives of animals, realisation is slowly dawning that we were probably too egoistic to acknowledge that animals have intelligence and emotions!
