A type of evolution that occurs through small genetic changes over time, often leading to the development of new subspecies.
Microevolution can be observed in the changes of a population's traits over generations.
Microevolution is formed from "micro-" (from Greek "mikros", meaning small) and "evolution" (from Latin "evolutio", meaning unrolling or unfolding). The term refers to small-scale evolutionary changes within a species over time.
Think of 'small' ('micro-') changes in the way species 'unfold' or develop ('evolution') over time.
