Natural Selection
A measurement of how well you can survive and reproduce in an environment.
Fitness
The formation of a new species from a pre-existing species. Typically caused by isolation
Speciation
Study of prehistoric life through fossil record.
Paleontology
What type of evolution does phylogenetic trees show? Think what connects it all and tie it to a type of evolution
Divergent Evolution
What evolves: Individuals or populations?
Populations
Lots of offspring and limited resources cause for competition.
Ex: 100 out of 500 offspring survive.
Overproduction of offspring
Occurs when two populations occur in response to each other.
Coevolution
How is embryology evidence of evolution?
There are similarities in the embryos of vertebrates early in development!!!
Which species is diverged first?
Cobra
Term to describe movement of genes in or out of a population; ex; migration
Gene Flow
A feature that allows an organism to survive in its environment.
Adaptation
Occurs when a catastrophic event changes the environment suddenly, such as a meteor....be specific!!!!
Mass Extinction
How does biochemistry provide evidence of evolution?
Pseudogenes and similarities of DNA predict common ancestry.
Which species is most related to the Ibex?
Camel
Type of structure that are similar but evolved independently in different organisms due to serving similar purposes.
Analagous Structures
Beneficial traits become more common over time due to this/
Descent with Modification
Unrelated species evolve similar characteristics because they live in similar environments.
Convergent Evolution
Vestigial Structures
Which trait is only seen in the fennec fox?
Binocular vision
Study of geographic distribution of plants and animals.
Biogeography
The ultimate source of genetic variation.
Mutations
Bursts of change followed by periods of stability
Punctuated Equilibrium
Species that exist only in one geographic region
Endemic Species
Which two organisms are most related:
The Camel and Fennec Fox OR Camel and Condor?
The camel and fennec fox....they have a more recent common ancestor.
What are three criteria for genetic equilibrium? (No evolution occurring)
1. Large Population
2. Random Mating
3. No Migration
4. No Mutation
5. No Natural Selection
