Evolution Definition

Evolution (evo‧lu‧tion, ˈɛvəluːʃ(ə)n) is defined as a change in the genetic composition of a population over successive generations. When we hear “evolution”, we often think of a progressive change. However, evolutionary changes are not directed toward perfection or even toward some defined goal. Evolutionary changes involve interaction between available genetic variants and the environment in which they exist. For evolution to proceed, there are vital key players: genetic variation, natural selection, and genetic drift.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
