Timeline of the evolutionary history of life This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth In biology , evolution is any change across successive generations in the heritable characteristics of biological populations. Evolution Evolution is change in the heritable characteristics of biological populations over successive generations These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

Evolutionary Psychology Evolution Definition ThoughtCo Evolutionary psychology is a relatively new scientific discipline that looks at how human nature has evolved over time as a series of built up psychological adaptations Many evolutionary biologists and other scientists are still reluctant to recognize evolutionary psychology as a valid science.
