Scientific
Evolution by Natural Selection
Summary
Proposed by Charles Darwin in his 1859 book "On the Origin of Species," this theory is the cornerstone of modern biology. It provides a scientific explanation for the diversity of life on Earth, proposing that all species of life have descended over time from common ancestors through a process of gradual change driven by environmental pressures.
"It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change."
— Charles Darwin (paraphrased)
