Evolution and Genes

Evolution Evolution is the sum of all transformations undergone by a particular primitive life form over time

Natural Selection Natural Selection is a theory developed by the scientist Charles Darwin to explain the evolution of species In this theory individuals whose physical and behavioural characteristics are best adapted to their habitat have a better chance of reproducing and passing on their characteristics

Genetic Mutation The nucleus of the cell contains the chromosomes that have the genes for that species A gene can become mutated so that it is different from “the normal form” Individuals who carry a beneficial mutation have a better chance of survival and therefore a better chance of passing on that gene through reproduction
