Charles Darwin’s theories of natural selection suggest that being mean, deceptive and selfish are the route to success in life. But, actually, science suggests that on a personal level, it may pay to be nice.
Migrating birds fly in a V-formation to take advantage of the aerodynamic effects of flying behind another bird. Remarkably, birds take turns at the front despite no obvious benefit to the individual. A new study explains why they do it, and why cooperation can be a powerful evolutionary tool.
Left-handers aren't very common. In fact , they only represent about 10 percent of the human population. But a new study suggests that the reason lefties are in the minority isn't anything suspect—rather, it boils down to the fact that the human race cooperate more than they compete.
Think only jerks can catch a break in this cruel world? Nope. David Rand, a Harvard University researcher, studied the behavior of 800 individuals he recruited through Amazon's Mechanical Turk to prove it.
Humans are the only animals who display loyalty to individuals we don't personally know. Scientists had assumed this was a new development made possible by the rise of centralized governments. But it might actually be part of how we evolved.
If you're ever being attacked by a lion, find a herd of elephants as quickly as you can...but if they're not led by an older female, you're dead meat. It's more remarkable evidence of elephants' ability to learn and cooperate.
