The Genetical Theory of Natural Selection

The Genetical Theory of Natural Selection combines Charles Darwin's ideas on evolution with modern genetics. It explains how traits beneficial for survival and reproduction can be passed down through generations due to genetic inheritance. Variations in traits arise from mutations and sexual reproduction. When individuals with favorable traits reproduce, they are more likely to pass these traits to their offspring. Over time, this process leads to the adaptation of species to their environments, explaining the diversity of life. Essentially, it shows how genetics underpins the natural selection process that shapes evolution.
