Cladograms and phylogenetic trees are both examples of evolutionary trees. While both types contain groups of organisms that descended from a common ancestor, phylogenetic trees are typically constructed in a way where the length of the "branches" and their relation to other organisms on the tree represent the inferred evolutionary change that actually occurred. On the other hand, cladograms typically display "branches" that are of equal distance to one another. The primary purpose of this assignment is for you become comfortable reading evolutionary trees, to accurately determine recent common ancestors, to identify which organisms are extinct (dead), extant (living), and the general relationship genetics plays in the overarching process of evolution. 1.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
