The day for that serious revision may be at hand.

Some of the earliest Americans turn out to have been artists. A bone fragment at least 13,000 years old, with the carved image of a mammoth or mastodon, has been discovered in Florida, a new study reports. While prehistoric art depicting animals with trunks has been found in Europe, this may be the first in the Western Hemisphere, researchers report Wednesday in the Journal of Archaeological Science.

A team of researchers who got a first look at a foot bone from famous fossil Lucy who lived 3 million or more years ago, and concluded this ancestor was fully comfortable with life on the ground, rather than in the trees.

A shrunken brain may potentially lie inside the fossil skull of a newfound candidate for the immediate ancestor to the human lineage, researchers now reveal. This new species, dubbed Australopithecus sediba, was accidentally discovered in South Africa by the 9-year-old son of a scientist. Two members of this hominid were introduced to the world last week — a juvenile male and an adult female, who might have known each other in life and who could have met their demise by falling into the remains of the cave where they were discovered.

A fossil skeleton of a child discovered in a cave system known as the Cradle of Humankind may represent a previously unknown stage in the evolution of man, The (London) Sunday Times reported. The skeleton, which is almost complete despite being two million years old, is believed to belong to one of the hominid groups that includes humans.

Ardi lived 4.4 million years ago in the woodlands of East Africa. She spent most of her time in the trees. She stood about four feet tall, weighed 110 pounds, and had long arms, short legs, and a grasping big toe that was perfect for ...
