Sea lampreys excited by eau de liver bile
The sea lamprey is a parasitic, eel-like fish with a fearsome, tooth-covered "oral disk" instead of a regular mouth. When attacking, the lamprey rears its head, and clamps its oral disk onto the skin of other fish. With its grasping tongue, it feeds on blood and body fluids for an average of 76 hours,...

Evolution of intelligence
Woody Allen once famously said that the brain was his second favorite organ. And it is well-established that having a big one, as with Allen's "first favorite" organ (I'm guessing he wasn't referring to his liver), confers high status on its owner.

Humans emerged out of Africa again and again
Everyone knows that humans came out of Africa, but until recently nobody knew that they came in at least two major waves of migration, about 600,000 and 95,000 years ago. The finding comes from a major analysis of newly derived human genetic trees, published today in Nature.

Tracing the evolutionary flight of the dodo
A strong contender for the title of most misunderstood animal must be the flightless dodo, the bird universally derided as fat, slow and stupid. To top it all, it's dead.

Living under pressure
Life, as we knew it only a few decades ago, needed sunlight and warmth. No one imagined that anything could survive in extreme environments -- in intolerable places such as high-pressure, high-temperature deep-sea vents or under Antarctic ice sheets.

Of arms races and sex battles
On Valentine's Day, what better subject to tackle than sex? Well, maybe love, but that's not what gets evolutionary biologists all hot and bothered. Sex is where it's at -- the battle between the sexes. Males and females interact like two superpowers engaged in an arms race -- each escalation in arms...

Hypersexual farming
Humans have practiced selective breeding for thousands of years to develop plants, animals and fungi better suited for human use than they are in their natural states. No genetic engineering is required, yet the genes of selected strains are different, "improved." Even people opposed to genetic modification...
