Change over time
What is Evolution
Same structure different function
What is Homologous
Preserved remains of ancient organisms
What are Fossils
The study of fossils
What is Paleontology
Type of isolation caused by mating practices (ie bird's mating song)
What is behavioral isolation
Type of isolation caused by incompatible mating seasons
What is Temperal Isolation
Another name for natural selection
What is survival of the fittest
Evolution due to chance
What is genetic drift
Increase in the frequency of both extreme alleles in a population
What is Disruptive selection
This type of evolutionary process is supported when transitional fossils are found in multiple rock layers
What are gradual changes?
Bringing in new alleles from another population
What is gene flow
An example is geographical isolation - Darwins' Finches
What is Allopatric
Male Donkey + Female Horse = Mule
What is Postzygotic Isolation
This impacts small populations more than large
What is genetic drift
Type of isolation where different mating seasons may create a barrier
What is temporal isolation
All of the available genes within a population
What is gene pool
The theory that only living organisms can make other living organisms
What is biogenesis
Ancestral organism shared by two or more descendent lineages
What is a common ancestor
What is the Hardy - Weinberg
This term describes how often a specific allele appears in a population.
What is allelic frequency
