Tenets of natural selection

The theory of evolution by natural selection is attributed to 19th century British naturalist Charles Darwin. The theory is widely accepted based on fossil records, DNA sequencing, embryology, comparative anatomy and molecular biology. Darwin’s finches are examples of evolutionary adaptation.

Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, most characteristics of organisms are inherited, or passed from parent to offspring, although how traits were inherited was unknown. Second, more offspring are produced than are able to survive.ADVERTISEMENTS: So main theories of evolution are: (I) Lamarckism or Theory of Inheritance of Acquired characters.
