group consisting of modern humans, extinct human species, and all of our immediate ancestors.
What is hominin?
300
You can get one from your mom and dad, and every gene is independently assorted.
What is independent assortment?
300
Bottleneck effect and founder effect
What are the two effects that happens when genetic drift takes place.
300
A parent species split into two or more reproductively isolated populations.
When does speciation occur?
300
based on the decay of radioactive isotopes, and provides absolute ages of fossils.
What is radiometric dating.
300
Two groups share the same traits due to shared ancestory.
What is homology?
400
Genes Located near each other on the same chromosome and tend to travel together.
What is linked genes?
400
Change in nucleotide sequence of DNA
What is mutation.
400
A population is reproductively cut off from populations of the parent species.
When does key events occur in speciation?
400
Has a large impact on the evolution of biodiversity.
What is continental drift?
400
When two groups that are not related develop the same trait, not due to shared ancestory.
What is Convergent evolution.

Genetic Drift is changes in gene frequency due to chance, while migration increases what?
What is genetic variation?
500
Initial block to flow is a geographic barrier that physically isolates the splinter population.
What is Allopatric speciation?
500
Divides Earth's history into a consistent sequence of geologic periods.
What is the geological time sequence?
500
Approximately 2-3 million years ago.
What is the time of the greatest hominin radiation.
