WebApr 11, 2024 · “@Anthrofuentes @FondOfBeetles @SwipeWright There are species where typical forces of sexual selection are reversed, where selection is stronger for females for example, but this does not mean that the biological meaning of the sexes is reversed. There are still the males that produce the sperm and the females the eggs.” WebGenetic variation, as well as changes in the environment, cause characteristics of organisms to change over time. This process of natural selection leads to the evolution of new species.

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 … 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.
