The basic postulates of Darwinism are: (i) Enormous power of fertility: Every living organism has the power to reproduce rapidly. Hence there is a danger of population overrunning the food and other facilities.

They are as follows: heredity, reproduction, physical traits that differ, and variation in the number of offspring produced by each individual. Suggest Corrections. 1.Origin. The trait must have caused the organisms to evolve because it made the organisms that had it more fit for survival. If the organisms changed due to another mechanism, such as genetic mutation, it was not due to natural selection.

The primary mechanism for evolution is natural selection.Natural selection is the process in which living things with beneficial traits produce more offspring than others do. This results in changes in the traits of living things over time. In Darwin’s day, most people believed that all species were created at the same time and remained unchanged thereafter.Natural selection Learning objectives: • Describe four postulates of natural selection - variation, heritability, struggle for existence, differential survival and reproduction • Contrast and compare papers by Darwin and Wallace • Analyze data to obtain evidence for these postulates • Apply four postulates to determine whether natural selection is …But U.S. National Science Foundation-supported research from Michigan State University suggests that natural selection also has the power to keep things the same.
