Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.

Despite recent advances in the study of eukaryogenesis, much remains unresolved about the origin and evolution of the most complex domain of life.

The broken-wing display, in which birds fake being wounded to protect their nests from predators, is found across the avian phylogenetic tree, a study finds.

All multicellular creatures interact with bacteria, but some have taken the relationship to another level with highly specialized structures that house, feed, and exploit the tiny organisms.

A survey of more than 200 whale skulls has unveiled bursts of evolution over the past 50 million years.

Noncoding RNAs are proving to be critical players in the evolution of brain anatomy and cognitive complexity.

Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

Once thought of as a mere motor coordination center, the “little brain” is now appreciated as participating in higher neurological processes.

Meet the team trying to restore mollusk populations with the help of underwater speakers.

A strange layer in the fossil record contains evidence that fern populations exploded following the mass extinction that ended the Cretaceous period. Scientists want to know why.

The compounds responsible for the earthy smell of recent rain are produced by a wide variety of bacteria and fungi. Recent research sheds light on why microbes bother.

Female fruit flies assess the physical symmetry of male suitors through the songs they sing, a study claims.

The normal functions of peptides that aggregate in Alzheimer’s, Parkinson’s, and Huntington’s have been largely overlooked by scientists, but some argue that they are critical for understanding the development of disease.

Today’s extinction rates are sky-high. But scientists debate if that’s sufficient evidence to conclude that Earth is undergoing a mass extinction event—or whether that’s even a helpful designation.

A study traces the effects of a mite outbreak from the earth to the heavens.

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

The fish use their stomach to swell up to three times their size. Is this why they can’t use the organ to digest proteins?

Researchers are turning to the immune system for help in treating addiction and preventing overdose.

Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.
