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.

Applying new analytic methods to nearly 16,000 ancient genomes reveals natural selection has acted on hundreds, not dozens, of genes in West Eurasia over the last 10,000 years. More than half of the ...

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 ...

NASA had a big – and little – problem. For a small satellite, the agency needed a tiny antenna, with very specific communication capabilities and very strict limits on size and weight. The agency gave ...
