Three ultra-endurance athletes have just done something most would consider insane: They ran the equivalent of two marathons a day for 111 days to become the first modern runners to cross the Sahara Desert's grueling 4,000 miles.

ATHENS The marathon was inspired by suffering, and on the day an event that is as much a test of character as a test of endurance returned to its Olympic roots and the evocative marble horseshoe that is Panathanaiko stadium, the suffering returned, too.

The sophistication of the human brain is not simply the result of steady evolution, according to new research. Instead, humans are truly privileged animals with brains that have developed in a type of extraordinarily

It is common wisdom among runners and other sports enthusiasts that lactic acid is the enemy of endurance. The chemical is a byproduct of metabolism during periods of intense exercise, when oxygen supplies cannot keep up with energy output.

Olympic champions have their parents to thank for their physiology&#151;but no one is born a world-record holder. That also requires training, nutrition, desire, and determination.

Researchers analyzing variation in the human genome have concluded that human evolution accelerated enormously in the last 40,000 years under the force of natural selection.

Scientists took a fresh look at human evolution through tiny hitchhikers that have clung to humans and their relatives for centuries - lice.

No one has ever doubted that, in the beginning, primitive man learned to walk before he could run. But how about it taking three million years for that second part &#151; after the whole walking thing was already down? Or, when it finally happened, the idea that simply being able to run radically propelled our evolution as a species?
