type of natural selection that favors one extreme phenotype ex. months
occurs when the action of a single gene influences several seemingly unrelated phenotypic effects; one gene affects several of traits
What was the most successful genus of the Pliocene?
formation of one or more new species via reproductive isolation

states that within a species of endotherms, more heavily pigmented forms tend to be found in more humid environments.
Transcription factor
A gene which controls the chemical action of other genes
Alfred Russel Wallace
Developed a theory of natural selection, similar to Charles Darwin.
can be your own worst enemies, genes getting passed on is what evolution is about, not because evolution is what evolution is about, not because evolution wants this to happen, but that those genes passed on most effectively are the ones still around today, evolution can build bodies that are organized with behaviors and tendencies, and bodies kill themselves in order to reproduce
Derived (Modified)
Referring to traits that are modified from the ancestral condition and thus diagnostic of particular lineages. Meaning that we cannot distinguish among them, but we can distinguish how they have evolved those forms.

Domestic Selection
Such as domestic dogs or animals, it is when animals are chosen or selected to breed. They possess certain traits that humans want in the animal's offspring. Also called "selective breeding". (Note that in nature, these traits would be selected against) (Darwin)

3. The evolved responses that enable individuals to protect and heal themselves.
4. How past adaptation of early humans to their environment now affects contemporary humans.

primate evolution was confined to the ________ _____
primate evolution was confined to the cenozoic era
what is the mixed-diet hypothesis of primate origins?

3 Observations by Darwin in the Origin of Species
1. All orgs have potential for explosive growth to outstrip food supply2. our population is stable however3. there must be a struggle for existence (nature full of variation, some variations must be favored)
