chimps
milhayser | July 15, 2015As researchers continue to document the intelligence and emotional acuity of animals, beasts begin to look more like brethren, and food more like friend. On Pharyngula, PZ Myers shares a decision by the U.S. Fish and Wildlife Service that gives chimpanzees used in research the same endangered status as their wild cousins. According to Science, "organizations that want to continue working with chimpanzees will have to document that the work enhances the survival of the species and benefits chimps in the wild." PZ writes, "I want to see more studies done on our closest relatives — but it has to…
edyong | November 11, 2009Today, a new paper published in Nature adds another chapter to the story of FOXP2, a gene with important roles in speech and language. The FOXP2 story is a fascinating tale that I covered in New Scientist last year. It's one of the pieces I'm proudest of so I'm reprinting it here with kind permission from Roger Highfield, and with edits incorporating new discoveries since the time of writing.
The FOXP2 Story (2009 edition)
Imagine an orchestra full of eager musicians which, thanks to an incompetent conductor, produces nothing more than an unrelieved cacophony. You're starting to…

As if job prospects weren't already bad enough for myrmecologists, now we're competing with chimps.
At least they haven't figured out how to make pooters. Yet.
edyong | August 3, 2009Swine flu has made the world all too aware of the possibility of diseases making the leap from animal hosts to human ones. Now, we know that another disease made a similar transition from chimpanzees to humans, several thousand years ago. This particular infection is caused by a parasite, and a very familiar and dangerous one - Plasmodium falciparum, the agent responsible for malaria.
Transmitted by the bite of mosquitoes, P.falciparum infects over 500 million people every year. Its closest relative is a related parasite, Plasmodium reichenowi, which infects chimpanzees. Leading an…
edyong | March 26, 2008Would you gamble on a safe bet for the promise of something more? Would you risk losing everything for the possibility of greater rewards? In psychological experiments, humans tend to play it safe when we stand to gain something - we're more likely to choose a certain reward over a larger but riskier one. Now, we're starting to understand how our two closest relatives deal with risk - bonobos, like us, tend to be risk-averse while chimpanzees usually play the odds.
Sarah Heilbronner from Harvard University studied the attitudes of five chimps and five bonobos to risky decisions. All the…

Chimpanzees may not be able to recite Hamlet or giving rousing speeches but there is no doubt that they are excellent communicators. They exchange a wide variety of sophisticated calls and gestures that carry meaning and can be tailored to different audiences.
The sophistication of chimp communication doesn't stop there. Jared Taglialatela from the Yerkes National Primate Research Center has found that chimp signals and human speech are both strongly influenced by the same area in the left half of the brain - a region called the inferior frontal gyrus (IFG).
In humans, the left IFG is home…
