What is the name used for the traits written on a cladogram?
Derived Traits
200
All new traits that arise in populations are the result of this naturally occurring phenomenon.
mutation

Organisms that are physically separated, preventing reproduction, are experiencing what type of reproductive isolation?
Geographic isolation
200
The type of genetic drift is the result of some disaster that takes out a large portion of a population of organisms
Genetic Bottleneck
200
These types of structures are similar in closely related species. They indicate that some common ancestor also had those parts.
Homologous structures
200
This can found where lines intersect at a node on a cladogram.
Common ancestors

What type of selection is depicted here?
Disruptive selection
300
This type of isolation involves mismatching cultures, behaviors, or mating practices.
Behavioral isolation

A species of mouse ranges in colors from black to a light brown. This species lives in areas covered in lots of sand. Predators who see mice are likely to eat them. What type of selection is likely to ensue
directional selection

What is the name for the concept that states that organisms of the same species are capable of breeding and producing fertile offspring
Biological Species Concept
400
This type of genetic drift occurs when a portion of a population is removed from its original area and put somewhere else.
