Florida International University researchers have traced the evolution of bioluminescence in deep-sea shrimps.
Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. These early terrestrial vertebrates were probably also able to hear 300 million years ago, as shown in a new study by Danish researchers.
Charles Darwin's theory on evolution still holds true despite lower mortality and fertility rates in the modern world, according to new research by the University of Sheffield.
Evolution is often perceived as being a "directional" or "adaptive" process. We often think of species evolving to become stronger or faster, or to have sharper teeth, for example. And we tend to see this as being inherently ...
Scientists said Wednesday they had amassed the first evidence to back theories that people fall into two broad categories—promiscuity or faithfulness—when it comes to sex.
How a brilliant-green sea slug manages to live for months at a time "feeding" on sunlight, like a plant, is clarified in a recent study published in The Biological Bulletin.
Migrating birds 'share the pain' of the arduous task of leading a v-formation, so that they can then take turns saving energy by following in another bird's wake, a new study shows.
The ascent of multi-celled life or multicellularity is a major evolutionary transition. Multicellularity evolved independently at least 25 times among eukaryotes, and complex multicellularity (characterized by intercellular ...
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
