Birds do it. Bees do it. But primate species don't sing and dance, except for Homo sapiens. Why is music-making part of human nature, then? Why do we enjoy singing in three-part harmony or clapping together in church, which wouldn't appeal for a single second to our chimp or orangutan cousins? This paper proposes an explanation: Music, it says, makes little kids nicer. Maybe it evolved because it made our ancestors more cooperative, and hence more successful.

It’s been a very hot summer here in New York City. And the city smells. It’s more than the smell of baking asphalt, exhaust fumes, and lack of deodorant—these smells are around all year. The heat has awakened older smells. Around midday, if you happen to stroll down by the South Street Seaport you can [...]... Read more »

It is possible that a much earlier than previously known date for the use of flaked stone tools has been established in Ethiopia, dating to prior to 3.39 million years ago.

The newly reported Saadanius hijazensis may or may not be a "missing link" but in order for this monkey to climb onto the primate family tree, a new branch had to be sprouted. So, not only is Saadanius hijazensis a new species, but it is a member of a new taxonomic Family, Saadaniidae, which in turn is a member of a new Superfamily, Saadanioidea. Why is this important? It's complicated. But not too complicated.

A major scandal looks to be in progress involving Harvard Professor Marc Hauser, a psychologist and popular author whose research on the minds of chimpanzees and other primates is well-known and highly respected. The Boston Globe has the scoop and it's well worth a read (though you should avoid reading the comments if you react badly to stupid.)Hauser's built his career on detailed studies of the cognitive abilities of non-human primates. He's generally argued that our closest relatives are smar........ Read more »

Georges Bank is a very large shallow area in the North Atlantic, roughly the size of a New England state, that serves as a fishing ground and whaling area (these days for watching the whales, not harpooning them) for ports in New England, New York and Eastern Canada. Eighteen thousand years ago, sea levels were globally at a very low point (with vast quantities of the Earth's water busy being ice), and at that time George's Bank would have been a highland region on the very edge of the North A........

It is well established among those who carry out, analyze, and report pre-employment performance testing that slope-based bias in those tests is rare. Why is this important? Look at the following three graphs from a recent study by Aguinis, Culpepper and Pierce (2010):

What Makes Humans Unique (IV): Shared Intentionality – The Foundation of Human Uniqueness? Shared or collective intentionality is the ability and motivation to engage with others in collaborative, co-operative activities with joint goals and intentions. (Tomasello et al. 2005). The term also implies that the collaborators’ psychological processes are jointly directed at something and take place within a joint attentional frame (Hurford 2007: 320, Tomasello et al. 2005).

How do you persuade people to eat less and exercise more? We love to think it's a matter of getting them to see facts and make good decisions, because that implies that people are thoughtful and that their choices matter. But this paper, published online yesterday by the Journal of Adolescent Health, points to a more humble solution: Ignore people's thoughts and feelings, and just move the food further away.
Why don't we have more policies like that? I think it's because we........ Read more »

The anopheles mosquito, Anopheles gambiae, is the primary vector for human malaria. Mosquitoes in general, the A. gambiae included, find their prey by tracking body odor exuded from the breath and skin. Apparently, the composition of body odor determines A. gambiae's preference for one individual over another. It has been known for some time now that A. gambiae preferentially seek out and draw blood from pregnant women (Linsay et al 2000; Ansell et al 2002; Himeidan, Elbashir and Adam 2004), ........
