Evolution Part 1 Flashcards
The idea that species change over time to best adapt to their environment
Evolution
Differences among individuals in a group
Variation
The ability to conform to the environment
Adaptation
The idea that if an individual survives to pass on their genes, they are more fit for an environment
Fitness
Diminished inside because of disuse
Vestigial Structure
Similar structures, but not because of common ancestors
Analogous Structure
Similar structures because of a common ancestor
Homologous Structure
Similar structures on unrelated species because of similar environments
Convergent Evolution
Related species evolving differently because of different environments
Divergent Evolution
Species evolving from a common ancestor
Speciation
Two species evolving complementary structures because of close interaction
Coevolution
Evolution that occurs in short bursts, followed by periods of no evolution
Punctuated Equilibrium
Evolution that occurs in consistent small changes over time
Gradualism
