resistancePhysiological Adaptation

Any body structure that is reduced in function is known as a _______

Vestigial structure

______ is the splitting of 1 species into 2 or more

speciation

Similarities in structure and arrangement—likeness indicates a genetic relationship through a common ancestor is known as

______

Homologous structures

Which type of genetic drift is caused by catastrophic events like a natural disaster or habitat loss?Bottleneck effect

What is the random effect that can occur when a small population settles in an area separated from the rest of the population and interbreeds, producing unique allelic

variations?Founders effect

A brown mouse blends in with his surroundings. This is an example

of ________Camouflage

List a vestigial structure in humans.

Wisdom teethAppendixEar muscles

Change in allele frequencies in a gene pool due to chance is known

as _______Genetic Drift

Two organisms live in close proximity, but rarely interact due to living in different habitats. This is known as __________

isolation.Habitat

The environment acted directly on organisms to produce hereditary change

in relation to need, use or disuse is known as _____________

Acquired Traits

_____ is the process in which a large population declines in

number, then reboundsBottleneck effect

What type of evolution happens in a shorter amount of time?

Microevolution

Who’s theory was based on the idea that the environment acted directly on

organisms to produce hereditary change in relation to need, use or disuse.

Lamark

When one organism looks like a dangerous organism, this is a

structural adaptation called_____.mimicry

___________ is a change in the gene pool of a population in response to various

stimuli exhibited by a species OVER TIME

Evolution

It is impossible for a monkey and a lion to reproduce. This is known

as____ isolation.mechanical

Which type of evolution requires speciation?

Macroevolution

__________ may arise over many generations (Ex: mimicry and

camouflage)Structural adaptations

Two species are separated by an ocean. This is referred to as_________ isolation.

Geographic

_________ is evolutionary change below the level of species, and refers to changes in the frequency within a population or a

species of its alleles

Microevolution

What is the name of the ship where Darwin did his studies for

his evolution theory?HMS Beagle

Two species of frogs live in close proximity, but reproduce at different

times of the year. This is known as ___________ isolation.

Temporal

__________ is any evolutionary change at or above the level of species.

Macroevolution

What organism did Darwin use to base a lot of his evolutionary

ideas? Finches

Two species of birds, meadowlarks, have overlapping ranges and are similar in appearance, but their songs separate

them. This is known as_________ isolation.

Behavioral

If a lion and a tiger mate, their offspring is a liger. The liger is sterile and cannot reproduce. This is known as________

isolation.Gamete

Any trait that aids the chances of survival and reproduction

of an organism is known as __________

Adataption
