Evolution and Diversity

Welcome to SAT Biology! Start your test preparations with the origins of life and how it has evolved over time. Why can some species survive the harshest conditions, while others die off rapidly? Explore how new species are formed and diversify via speciation as well as how all organisms are classified.
