Darwin's Principles
History of Evolution
Types of Evolution
Adaptations
Population Genetics
100
Some traits are ________
heritable
100
Who is the guy that came up the same theory of natural selection as Darwin?
Wallace
100
Common traits that species with a common ancestor share.
Homologous structures
100
Type of adaptation that allows for an animal to blend in.
Camouflage
100
A change in allele frequency resulting from chance.
Genetic Drift
200
More offsping are __________ than can possibly __________.
born; survive
200
The process of a species changing over time.
Evolution
200
When one species evolves into several different species.
Divergent evolution
200
The measure of how much a trait contributes to the survival of the next generation.
Fitness
200
Random changes in the structure of DNA.
Mutation
300
There is ____________ among species
variation
300
Darwin believed that organisms had a _______ _________, but evolved based on their environment.
Common Ancestor
300
When organisms that are not closely related develop similar traits to survive in similar environments.
Convergent evolution
300
Type of adaptation where a species will copy another for its benefit.
Mimicry
300
Random movements of individuals across populations (immigration and emigration)
Gene Flow
400
Individuals with certain traits are _________ likely to _________ than others
more; survive
400
Where did Darwin make his revolutionary observations about tortoises and finches?
Galapagos islands
400
When 2 species evolve together, usually to benefit one or both of the species.
Co-Evolution
400
Traits shaped by natural selection to increase the fitness of an individual.
Adaptations
400
Choosing a mate for a specific reason or trait
Non-Random Mating
500
Theory that states that organisms best adapted to their environments have a better chance at reproducing.
Natural Selection
500
Lamarck believed that species could change their traits in their lifetime by either _______ or _____ _______ certain traits.
using; not using
500
Rapid spurts of evolution show abrupt changes in the fossil record, usually caused by a drastic environmental change
Punctuated equilibrium
500
Type of adaptation where bacteria are no longer killed by what use to kill them.
Antimicrobial resistance
500
States that when allelic frequencies are constant there is no evolution taking place
