 | The world's largest species of monkey "chooses" mates with genes that are different from their own to guarantee healthy and strong offspring, according to a new research study. ...> Full Article |
 | The most extensive DNA study to-date of Africa's rarest monkey reveals that the species had an intriguing sexual past. Of the last two remaining populations of the recently discovered kipunji, one population shows evidence of past mating with baboons while the other does not, says a new study in Biology Letters. The results may help to set conservation priorities for this critically endangered species, researchers say. ...> Full Article |
 | Researchers comparing the fetal development of the eye of the owl monkey with that of the capuchin monkey have found that only a minor difference in the timing of cell proliferation can explain the multiple anatomical differences in the two kinds of eyes. ...> Full Article |
Researchers at Harvard Medical School have identified a gene in Asian monkeys that may have evolved as a defense against lentiviruses, the group of viruses that includes HIV. The study, published February 29 in the open-access journal PLoS Pathogens, suggests that AIDS is not a new epidemic.

The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. The conventional theory is that primates evolved trichromatic color vision to assist them in foraging, specifically by allowing them to detect red/orange food items from green leaf backgrounds. However, the results from several empirical studies have called into question the extent to which trichromacy functions in foraging and if it provides a performance advantage over dichromatic primates (who lack red-green color vision). Other studies have suggested that trichromacy evolved in primates so that they could use physical traits like red skin in socio-sexual communication, such as a male providing information to a female about his mate quality.

 | An international research team has documented the link between the way an animal moves and the dimensions of an important part of its organ of balance, the three semicircular canals of the inner ear on each side of the skull. The team's article on its research will be published on June 26 in the print edition of the Proceedings of the National Academy of Sciences and in the journal's online early edition during the week of June 18 to 22. ...> Full Article |
Every day humans make thousands of decisions, small and large, based on the information at hand and their assessment of the potential outcome of those choices.

 | You might call it a tale of 'monkey see, monkey do.' Researchers at Ohio University have found that after primates evolved the ability to see red, they began to develop red and orange skin and hair. ...> Full Article |
The human and chimpanzee genomes vary by just 1.2 percent, yet there is a considerable difference in the mental and linguistic capabilities between the two species. A new study showed that a certain form of neuropsin, a protein that plays a role in learning and memory, is expressed only in the central nervous systems of humans and that it originated less than 5 million years ago. The study, which also demonstrated the molecular mechanism that creates this novel protein, will be published online in Human Mutation, the official journal of the Human Genome Variation Society.
