Monkey business: Researchers discover primitive forms of wealth
(Phys.org) —Comparisons between the stock market floor and a zoo are not far from the mark, according to a new study published today in the journal Proceedings of the National Academy of Sciences (PNAS) ...
Evolution's toolkit seen in developing hands and arms
Thousands of sequences that control genes are active in the developing human limb and may have driven the evolution of the human hand and foot, a comparative genomics study led by Yale School of Medicine researchers has found
Social networks shape monkey 'culture' too (w/ Video)
Of course Twitter and Facebook are all the rage, but the power of social networks didn't start just in the digital age. A new study on squirrel monkeys reported in Current Biology, a Cell Press publication, on Jun ...
Monkeys found to conform to social norms
Human tendency to adopt the behaviour of others when on their home territory has been found in non-human primates. Researchers at the University of St Andrews observed 'striking' fickleness in male monkeys, ...
Researchers find non-ape species engages in rapid facial mimicry
Organisation trumps size in primate brain evolution
(Phys.org) —The evolution of anthropoid primates, including monkeys, apes and humans, over the past 40 million years was largely driven by brain reorganization, and not brain size, according to new research ...
Fossil find adds three million years to oldest known old-world monkey
Study shows capuchins less receptive to others who refuse to help when asked
Nut-cracking monkeys use shapes to strategize their use of tools
Bearded capuchin monkeys deliberately place palm nuts in a stable position on a surface before trying to crack them open, revealing their capacity to use tactile information to improve tool use. The results ...
Owl monkeys who 'stay true' reproduce more than those with multiple partners, Penn study finds
Breaking up is hard to do—and can be detrimental to one's reproductive fitness, according to a new University of Pennsylvania study.
Networking ability a family trait in monkeys
Two years of painstaking observation on the social interactions of a troop of free-ranging monkeys and an analysis of their family trees has found signs of natural selection affecting the behavior of the descendants.
Estrogenic plants linked to altered hormones, possible behavior changes in monkeys
Eating certain veggies not only supplies key nutrients, it may also influence hormone levels and behaviors such as aggression and sexual activity, says a new study led by researchers at the University of ...
Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.
Monkeys put off sex by bystanders
Monkeys shy away from bystanders during copulation, irrespective of the bystanders' gender or rank. The new study, by Anne Overduin-de Vries and her team from the Biomedical Primate Research Centre in the Netherlands, also ...
