Natural selection fish
WebIn a large population, where there is random mating and no mutation, neither migration nor selection, allele and genotype frequencies become stable in one generation. This is called the Hardy-Weinberg equilibrium law, which is a crucial genetic model for the conservation of the population diversity and the genetic study of natural populations. WebHowever, they also had lungs that they used to breathe oxygen. Between 390 and 360 million years ago, the descendents of these organisms began to live in shallower waters, and eventually moved to land. As they did, they experienced natural selection that shaped many adaptations for a terrestrial way of life.
