The Princeton University evolutionary biologist studies how animals are changing due to human activity.

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.

Genes associated with preterm birth and protecting the fetus from the mother’s immune system appear to be regulated by HAND2.

The Harvard University evolutionary biologist pioneered the use of protein gel electrophoresis to study molecular genetics.  

Researchers are using experiments and observational studies to look for host genetic variation that could be partly determined by the gut microbiota.

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

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.

The largest study to date of the animals’ genetics provides robust evidence that they are adapting to survive a highly lethal, contagious cancer scientists feared would cause their extinction.

Throughout his career, the University of California, Berkeley, herpetologist named 144 species of salamanders.

The genome sequences of 51 giraffes from all over Africa contribute to the latest attempt in an ongoing pursuit to pin down a species number.

The offspring of crosses between related species can sometimes fill a new environmental niche, and such hybridizations may even lead to speciation.

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.

Researchers are getting creative to understand flight behavior in the fast-moving and tiny animals.

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.

Enhancers, short regions of DNA that direct gene expression, of species separated by 700 million years of evolution worked interchangeably, according to a new study.

The same toxin targets different receptors in prey and conspecifics to deliver either a lethal or non-lethal blow.
