Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.
A massive, well-preserved skull discovered in China in the 1930s belongs to a new species called Homo longi, researchers report, but experts remain skeptical about the evidence.
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
A mutant protein called Siglec-XII may promote carcinoma progression in humans, but inactivation of its gene seems to avoid the problem, according to a study.
Researchers are pulling from video games, sports broadcasting, meteorology, and even missile guidance technology to better investigate how insects have mastered flight.
A new analysis of the hand of the 4.4-million-year-old partial skeleton of Ardipithecus ramidus indicates that the human ancestor may have climbed and swung through trees like chimpanzees do.
A selective advantage may have led the modern human Y chromosome to sweep through the Neanderthal population after it was introduced via interbreeding more than 100,000 years ago.
