Principles of Natural Selection
This producing enough offspring to compete for resources in an environment.
What is the overproduction of offspring?
Refers to the variety of living things
What is diversity of life?
Proposed the theory of evolution by natural selection
Who is Charles Darwin
What is Variation?
Change in genetic information over time
What is Evolution?
This is a random trait introduced in to a population.
What is mutation?
Individuals with an intermediate value of an inherited phenotype have the advantage
What is Stabililizing Selection
The study of where species live
What is Biogeography
This is a trait that benefits an organism in an environment.
What is an adaptation?
He was an English naturalist that is credited with the Theory of Natural Selection.
Who is Charles Darwin?
This says that organisms more fit for their environments will survive.
What is natural selection?
When one species evolves into many
What is divergent evolution
Several individuals from a population break off and form new population
What is Founder Effect
This is a change in the frequency of alleles in a gene pool over time, heavily effects smaller populations.
What is genetic drift?
New organisms come into or out of a population
What is Gene Flow
Individuals of one extreme of a phenotype have the advantage over others
What is Directional Selection
The differences in the physical traits of organisms
What is variation
This is the selection of mates based on traits that do NOT aide in survival.
What is non-random mating (sexual selection)?
This si the measure of how well you can survive in your environment.
What is a survival of the fittest? or fitness?
Individuals of either extreme of an inherited phenotype have the advantage over the intermediate forms
What is Disruptive Selection
The ultimate source of genetic variation
What is genetic mutation
The physical process of horizontal gene transfer between bacteria
What is Conjugation
