This was the beginning of population thinking, whereby variation among individuals is the key to understanding evolution. Evidence that species change through time includes data on. (1) Earth's age and the fact of extinction. (2) the resemblance of modern to fossil forms in the same area. (3) transitional features in fossils.This last point was proven by geologists and astronomers. After the creation of the modern synthesis theory, the remaining four postulates were modified to include new information about genetics. Individuals are Variable Darwin knew that individuals were variable, that is, each individual in a population carried a unique set of traits.ISBN 019 512 183 X. Darwin's theory of evolution by natural selection is the logical outcome of three postulates: (1) individuals within species are variable; (2) some of these variations are heritable; and (3) individuals that reproduce the most are those with the most favorable variations. Thus, adaptive genetic variation forms the very basis ...[4] Darwin's Theory of Evolution - A Theory In Crisis Darwin's Theory of Evolution is a theory in crisis in light of the tremendous advances we've made in molecular biology, biochemistry and genetics over the past fifty years.
