What is natural selection? Natural selection is one of the basic mechanisms of evolution‚ along with mutation‚ migration‚ and genetic drift. It is the process in which organisms better adapted to their environment manage to survive‚ meaning that they breed more offspring that have their genetic characters‚ while those less adapted tend to be eradicated. What are the names of the scientists who first proposed the theory? Charles Darwin began expressing his theory of natural selection in the late

The theory of Natural Selection was first published by Charles Darwin in the 19th century after hearing that another scientist‚ Alfred Wallace‚ was publishing a similar theory. The basis of their theories was: 1. Variation in traits within individuals in specie’s generation. 2. Heritability- where some
