It is how living things change over time and how new species develop. The theory of evolution explains how evolution works, and how living and extinct things have come to be the way they are.

WebEvolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment. It is a non-random change in allele frequencies from one generation to the next. WebA species is a group of organisms able to interbreed and produce fertile offspring.

WebMar 15, 2024 · 1 INTRODUCTION. A growing body of work in experimental evolution, spurred by Stephen Jay Gould's idea of “replaying life's tape”, has begun to evaluate whether evolution follows a deterministic route in response to some environmental pressure (reviewed in Blount et al., 2024; Lobkovsky & Koonin, 2012; Losos, 2024).The question … WebEvolution is the process by which small changes in organisms occur over long periods of time and new species are formed.

WebNew alleles originate by mutation, a permanent change in the nucleotide sequence of DNA. Mutation is the ultimate source of the genetic variation that serves as raw material for evolution. In multicellular organisms, however, only mutations in cells that produce gametes can be passed to offspring and affect a population ' 3 genetic variability. Web1044. Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have lived on Earth.
