New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its ...

A mosquito lands on an arm. Within seconds, it finds the skin, inserts its mouthparts and begins feeding. Humans have been experiencing versions of this encount ...

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...

In fact, natural selection often leads to ever greater simplicity. And, in many cases, complexity may initially arise when selection is weak or absent. If you don’t use it, you tend to lose it.

Molecular evolutionary biologist Masatoshi Nei says Darwin never proved natural selection is the driving force of evolution — because it isn't. In a cavernous concert hall, before an eager audience of ...

The U.S. is the only developed country where controversy continues about teaching evolution in schools. Yet, there is little doubt that evolution happens, or that humans are products of evolution by ...

A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that natural selection has shaped modern human genomes far more than previously thought.

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual selection is where individuals with certain traits have higher reproductive ...
