These primitive single-celled organisms have adapted to living in temperatures over 900⁰F, or high salt environments that would kill most animals.  These types of prokaryotic cells are given the nickname __________________.

Survival and reproduction of certain individuals in a population over others, who have favorable and inherited traits, over time leads to evolutionary change in the entire population.  This is the definition of….

When scientists seek to organize different animals into a ‘tree’ with branch points to represent how one species split off from another, they look at shared derived character traits to organize the different animals, they look at similarity in structure, similarity in chemical composition, to build a diagram, representing these close evolutionary relationships.  What is this diagram called?

Structures shared by different organisms that perform different functions, but are similar in structure, and indicate a common ancestral origin. Example:  Vertebrate forelimb structures from a horse, a human, a fish, and a whale.
