What is the mechanism by which evolution occurs?

These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here). Each mechanism of evolution can be characterized by how it affects fitness, adaptation, the average phenotype of a trait in a population, and the genetic diversity of the population.

What are the 4 mechanisms that cause evolution?

Describe the four basic causes of evolution: natural selection, mutation, genetic drift, and gene flow.

What is the mechanism through which evolution occurs according to Darwin?

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

Which of the following concept is attributed to Charles Darwin?

Charles Robert Darwin gave the theory of evolution by natural selection. The theory was known as the theory of natural selection. He explained the process by which organisms change over time as a result of changes in behavioral traits.
