Biology – Evolution, Natural Selection and DNA

Course Level 2: Intermediate

Estimated Study Time: 2-3 hours

Evolution and natural selection are very important concepts that have revolutionized our understanding of biology. Natural selection is a process resulting in the evolution of organisms that are best adapted to their environment, usually occurring over thousands, and even millions of years.

In this course you will be introduced to the concepts of evolution and natural selection, the causes of these fundamental biological processes and how the success of a species can depend on changes to just one allele on one gene in one chromosome. You will study the naturally occurring variation within species and how mutations and reproduction continues this process. You will also be introduced to DNA, the blueprint of life forms on earth, by looking both at its physical structure and how it copies itself, and turns into the proteins that make up all living organisms.
