Abrupt shifts in the evolution of animals -- short periods of time when an organism rapidly changes size or form -- have long been a challenge for theorists including Darwin. Now a newly published ...

In 1943, a physicist and a biologist published a paper that confirmed one of the central pillars of Darwin's theory of evolution. The paper, by Max Delbrück of Vanderbilt University and Salvador Luria ...

Studying the genome of thale cress, a small flowering weed, led to a new understanding about DNA mutations. (Pádraic Flood) A simple roadside weed may hold the key to understanding and predicting DNA ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

The peppered moth is an iconic example of Charles Darwin’s theory of evolution by natural selection. For centuries peppered moths (Biston betularia) were common in the forests around Manchester, ...

Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...
