What causes descent with modification?

The descent with modification definition is the passing on of the genetic code from parent to offspring with changes that are in turn hereditary. The three mechanisms that can change the genetic code of a population are mutation, migration and genetic drift.

Who defined descent with modification?

For example, in the first edition of the Origin of Species (Darwin 1859, see http://darwin-online.org.uk/) Darwin uses the phrases “theory of descent” and/or “descent with modification” 21 times (on pages 12, 14, 189, 206, 320, 349, 351, 354, 358, 361, 399, 429, 444, 477, 479, 484, 493, 494, 496, and 497).

How does descent with modification explain the diversity of life?

First proposed by Charles Darwin in some of his early works, the theory of descent with modification states that species have evolved over time through the accumulation of incremental changes, eventually creating new forms that are so different as to be classified as species.
