A series of studies released today show that a long-extinct South African creature had an intriguing mix of human and apelike traits. But scientists say they still haven’t figured out where it fits on our evolutionary family tree. The human branch of the evolutionary tree, called Homo, is thought to have arisen from a group of ancient species called australopithecines. The newly studied species is a member of this group, and so its similarities to humans are enticing for tackling the riddle of how Homo appeared.

Neanderthals were big game hunters who feasted on mammoth and rhino but didn’t or couldn’t eat smaller, leaner meat.

Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time and wonder if it might provide a target for the development of novel anti-cancer treatments.

In an interview with Der Spiegel, geneticist George Church made some headlines by claiming that it will be possible to clone a Neanderthal in the near future.

It could be the muffled sound of singing in the shower or that sing-songy indecipherable voice from the Muppets' Swedish Chef. Surprisingly, scientists said the audio they captured was a whale imitating people. In fact, the whale song sounded so eerily human that divers initially thought it was a human voice.

Our ancestors didn't walk alone: Neanderthals and other ancient peoples shared Earth with them tens of thousands of years ago. Now, using new technology, scientists have sequenced with high precision the genome of one of those close but little-known relatives: an extinct people known as the Denisovans, who lived in and around modern-day Siberia.

Fossil by fossil, scientists over the last 40 years have suspected that their models for the more immediate human family tree — the single trunk, straight as a Ponderosa pine, up from Homo habilis to Homo erectus to Homo sapiens — were oversimplified. The day for that serious revision may be at hand.

Neanderthals weren't the only ancient cousins that humans frequently mated with, according to a new study that finds that East Asian populations share genes with a mysterious archaic hominin species that lived in Siberia 40,000 years ago. This group, the Denisovans, is known only by a few bone fragments: A finger bone, a tooth and possibly a toe bone, which is still undergoing analysis. The Denisovans likely split off from the Neanderthal branch of the hominin family tree about 300,000 years ago, but little else is known about their appearance, behavior or dress. But just as researchers have learned that ancient humans and Neanderthals mated, they've also found genetic echoes of the Denisovans in modern residents of Pacific islands, including New Guinea and the Philippines.

An analysis of 2 million-year-old bones found in South Africa offers the most powerful case so far in identifying the transitional figure that came before modern humans - findings some are calling a potential game-changer in understanding evolution....

Many modern-day humans may be carrying around a fragment of Neanderthal DNA on one of their sex chromosomes, a new study finds.
