Which came first: Primates' ability to see colorful food or see colorful sex?

06-25-2007 · EurekAlert!

Primates have a unique ability to distinguish red from green, but the reason why has been debated: Was it first to see ripe red fruit against green leaves or was it first the mating systems that communicate through red in skin and hair? This study incorporated evolutionary relationships among 203 primate species to show the sequential evolution of color vision, skin color, fur color and mating systems, and found that foraging came first.

Sex and prenatal hormone exposure affect cognitive performance, Yerkes scientists find
04-12-2007 · EurekAlert!
In one of the first research studies to assess sex differences in cognitive performance in nonhuman primates, researchers at the Yerkes National Primate Research Center have found the tendency to use landmarks for navigation is typical only of females. This finding corroborates findings in rodents and humans and is available in the online edition of Hormones and Behavior.

For primates, tourism can be less fun than a barrel of monkeys
07-13-2007 · EurekAlert!
Primate tourism, an economic benefit and conservation tool in many habitat countries, has exploded in popularity over the past two decades in places like China, Borneo, Uganda, Rwanda, Northern Sumatra, Madagascar, Gabon and Central America. New research by scientists in the United States, China and Japan, however, has found that some primate tourism practices are inappropriate because they provoke an unprecedented level of adult aggression that is proving deadly for infant monkeys.

Apes bite and try to break a tube to retrieve the food inside while children follow the experimenter's example to get inside the tube to retrieve the prize, showing that even before preschool, toddlers are more sophisticated in their social learning skills than their closest primate relatives, according to a report published in the Sept. 7 issue of the journal Science, published by AAAS, the nonprofit science society.

Einstein researchers' discover 'radiation-eating' fungi
05-22-2007 · EurekAlert!
Scientists have long assumed that fungi exist mainly to decompose matter into chemicals that other organisms can then use. But researchers at the Albert Einstein College of Medicine of Yeshiva University have found evidence that fungi possess a previously undiscovered talent with profound implications: The ability to use radioactivity as an energy source for making food and spurring their growth.

Animal food allergens unmasked
10-14-2007 · EurekAlert!
The relatedness of an animal food protein to a human protein determines whether it can cause allergy, according to new research by scientists from the Institute of Food Research in Norwich and the Medical University of Vienna.In theory all proteins have the potential to become allergens, but the study found that in practice the ability of animal food proteins to act as allergens depends on their evolutionary distance from a human equivalent.

Alzheimer's disease diagnosed 100 years ago today
11-03-2006 · EurekAlert!
One hundred years after the first diagnosis of Alzheimer's disease Nov. 3, 1906, researchers at the Yerkes National Primate Research Center, Emory University, are focusing on neuroscience, immunology and vaccine research to better understand how AD develops and progresses as well as to advance the treatment and prevention of this progressive brain disorder. AD, which currently affects 20 million Americans, gradually destroys memory and the ability to learn, reason, make judgments and communicate.

Monkeys don't go for easy pickings
07-17-2007 · EurekAlert!
Animals' natural foraging decisions give an insight into their cognitive abilities, and primates do not automatically choose the easy option. Instead, they appear to decide where to feed based on the quality of the resources available and the effect on their social group, rather than simply selecting the nearest food available. These findings have recently been published in the journal Animal Cognition.
