evolution is a process by which the gene pool of a(n) _______________ changes over time
What is an organism
100

Random change to genetic material

Mutation

100

_______________ theory that evolution happens in small , gradual steps over time.

Gradualism

100

This is the study of how creatures develop before being born or hatching from an egg.

Embryology

100
This occurs in the gametes and allows species to evolve
What are mutations
200

Name the theory that explains how organisms change because of adaptations that help them survive

What is natural selection

200

Random movement of individuals between populations which increases genetic diversity is known as (2 words)

Gene Flow

200

Flowers and pollinators are an example of this type of evolution....

Co-Evolution

200

Comparative Biochemistry suggests that molecules in species with a a recent common ancestor also share.... 

amino acid/DNA sequences

200
These served a purpose on our bodies at one time, but they don't anymore
What are vestigal structures
300

Evolution can be defined as any change in the _______ traits (physical or behavioural characteristics) with in a population over time

What are heritable traits

300

This occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. (2 words(=)

Non-Random Mating

300

Unrelated species evolve similar traits because they live in similar niches or have similar lifestyles. (2 words)

Convergent Evolution 

300

Similarities like elbows in the front limbs of mammals such as bats, penguins and alligators are called (two words)

What are homologus structures

300

This principle of Natural Selection states that individuals in a population will show differences

Variation

400

A massive amount of evidence from many different fields such as genetics, chemistry, paleontology, and mathematics, overwhelmingly suggest that all living things share a ________ ________ (two words) 

common ancestor

400

Certain individuals in a population have a higher survival and reproduction rate.

Natural selection

400

Diversification of a species into a number of different species is known as... (2 words)

Divergent evolution

400
Basilosaurid whales are an example of an _________  species (show a developmental stage between two organisms)

intermediate 

400

This type of speciation does not involve a barrier, but occurs when errors in meiosis result in gametes that produce offspring that are no longer able to reproduce with members of older generations. 

Sympatric speciation 

500
Islands, a large river, canyon or other barrier can cause an organism to develop different species
What is geographic isolation
500

Random change in the allelic frequency in a population, caused by something that shrinks a population size is called ... (2 words)

Genetic Drift

500

_______ ______ theory that evolution occurs with relatively sudden periods of speciation followed by long periods of stability

Punctuated Equilibrium

500

The fact that whales have placenta, give birth to live young, are warm blooded, no gills, and have lungs like land mammals, is proof of evolution from the field of ____________ ______________ (two words)

Comparative Anatomy

500

A type of reproductive isolation that prevents reproduction by making fertilization unlikely. 

Prezygotic Isolation.
