After domesticating potatoes 10,000 years ago, the ancient people of the Andes evolved to have more copies of a key gene ...
By analyzing the genetic material of thousands of ancient humans, researchers have mapped how natural selection influenced ...
When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most ...
Natural selection is usually understood in the context of change. When organisms deviate from the norm, they may gain advantages that let their lineages outlast those of their less-adaptable relatives ...
"Survival of the fittest" is the catch phrase of evolution by natural selection. While natural selection favors the most fit organisms around, evolutionary biologists have long wondered whether this ...
Whether it's more aggressive chickadees, snails with lighter coloring or pigeons with anti-pollution plumage, urban wildlife ...
In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...
The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. To suggest otherwise can provoke ...
