By analyzing the genetic material of thousands of ancient humans, researchers have mapped how natural selection influenced hundreds of physical and behavioral traits across West Eurasia over the past ...

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 ...

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 ...

Introduction. Definition of natural selection ; Relationship to genetic drift and evolution ; Restricted meanings of "natural selection" ; Modes of selection ; Summary -- Philosophical comments.

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 ...

We tested whether the location of mutations in our dataset was associated with epigenomic features, focusing on biochemical properties previously linked to mutation: gene expression, GC content, ...

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 ...

In a recent study, scientists have demonstrated a link between individual variation in risk-taking behavior and survival of animals in changing environments. For more than a century, scientists have ...

Whether it's more aggressive chickadees, snails with lighter coloring or pigeons with anti-pollution plumage, urban wildlife is trying to adapt to city life. Is it behavioral flexibility or true ...
