Natural selection is a central concept of evolution.It was proposed independently by the English biologists Charles Darwin and Alfred Russel Wallace in the middle of the 19th century (1858). Refashioning the story of human evolution, Wilson draws on his remarkable knowledge of biology and social behavior to demonstrate that group selection, not kin selection, is the premier driving force of human evolution. Evidence for large-scale evolution ( macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils. Artificial selection and natural selection are thought of as different types of selection, but at a fundamental (genetic) level they are essentially the same … It is also called alternative RNA splicing.In regular DNA translation, specialized proteins create messenger RNA from the DNA template.This mRNA then finds its way to a ribosome, where the RNA code is translated into the structure of a new protein.
