Synthetic theory of evolution incorporate knowledge

Question

How does synthetic theory of evolution incorporate knowledge from the Genetics and Molecular Biology in the darwinism?

Answer 1

Today it is known which variation of inherited aspects is created by the alterations in the genetic material of individuals, more precisely by the modifications or recombinations of DNA molecules. Small alters in the genetic material accumulate and newest phenotypical features come in view.

The carriers of such features then are submitted to the natural selection. From modern Biology it’s recognized that natural selection creates in a given population a raise in the frequency of alleles and genes more favorable to survival and reproduction; less beneficial genes and alleles tend to be eliminated.
