Evolution Basics
Darwin described evolution as this phrase meaning species change over time.
What is descent with modification?
Preserved remains of organisms.
What are Fossils?
Group of same species in one area.
What is a Population?
Favors average traits.
What is Stabilizing selection?
Science of naming organisms.
What is Taxonomy?
Genetic change in a species over time.
What is evolution?
Similar traits due to shared ancestry.
What is Homology?
All alleles in a population.
What is Gene pool?
Favors one extreme.
