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 ...

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.

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

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 ...

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 ...

Many people are familiar with the concept of natural selection and “survival of the fittest.” While modern humans may look like they’ve been at their “fittest” for hundreds of thousands of years, new ...
