Document Summary
The theory of evolution by natural selection was first proposed by charles darwin and alfred russel. Charles darwin and alfred russel wallace both came up with the theory that accounts for the appearance and perpetuation of varieties and of specific forms on our planet. Essay: on the variation of organic beings in a state of nature; on the natural means of selection; on the comparison of domestic races and true species. De candolle has declared that all nature is at war, one organism with another, or with external nature. The war, however, is not constant, but recurrent in a slight degree at short periods, and more severely at occasional more distant periods; and hence its effects are easily overlooked. Many practical illustrations of this rapid tendency to increase are during peculiar seasons, are the extraordinary numbers of certain animals. Essay:abstract of a letter from c. darwin.
