natural selection

By borrowing the idea of directed evolution, a technique used in both chemistry and biology that mimics the process of natural selection, the researchers combined precision with rapid output to achieve their ideal lipid "recipe."

Researchers were able to uncover traces of natural selection -- signs of genetic adaptation to environmental pressures -- that are undetectable in the DNA of modern Europeans.

Even human intelligence arose through the randomness of natural selection.

“And so natural selection sort of optimizes for organisms to converge on that same phenotype.”

Indeed, the warrah conundrum figured prominently in the development of Darwin’s ideas on evolution by natural selection.
