Natural Selection

Natural selection is the primary evolutionary mechanism by which heritable traits that enhance reproductive success become more prevalent in a population over successive generations while disadvantageous traits diminish.

Overview

First systematically articulated by Charles Darwin and Alfred Russel Wallace in 1858, it operates through four conditions: heritable variation exists, individuals overproduce offspring, and survival and reproduction are non-random, favoring traits that confer advantage. Over time this differential success reshapes the genetic composition of populations, driving adaptation and speciation.

Why it matters

Darwin's formulation fundamentally transformed humanity's understanding of life, placing organisms within a continuous natural process and challenging prevailing theological assumptions about purpose in nature — a shift as profound as the Copernican revolution. Natural selection remains one of the most unifying explanatory frameworks in the history of science.
