If you have a child, you're probably already aware of this.
The mechanisms of evolution include natural selection acting on the genetic variation among individuals, mutation, migration, and genetic drift. Descendants accumulated diverse modifications (adaptations) If you have a child, you're probably already aware of this. The descent with modification is defined by darwin as the transmission of the traits from one generation to the next generation, which gives rise to new species and shares the common ancestor. Change in the genetic composition of a population during successive generations, often resulting in the development of new species.

For example, the forelimbs of human, cats, whales, and bats share the same skeletal elements, even though the. Descent with modification by natural selection explains the adaptations of organisms and the unity and diversity of life. That is, complex creatures evolve from more simplistic ancestors naturally over time. Descent with modification by natural selection gives rise to adaptation in organisms.

Partly influenced by an essay on the principle of population (1798) by thomas robert malthus , darwin noted that population growth would lead to a struggle for existence in which favourable variations prevailed as others perished.
