Identify the four postulates of natural selection.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Identify the four postulates of natural selection. Describe how species evolve via natural selection. (Be sure to discuss the key aspects of natural selection: variation, heredity differential survival and reproductive success in your answer).

Sep 10, 2022 · natural selection acts on traits, mutations for advantageous traits are more likely to be passed on to the next generation, and natural selection favors some mutations. In the lab, Nachman examined dark mice from two different populations living hundreds of miles apart. The mice looked nearly identical.

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.Identify the four postulates of natural selection.
