Evolution Part 1 Flashcards
Idea the species change over time to adapt to environment
Evolution
Differences among individual within a species group
Variation
Change with environment
Adaptation
If those organisms survive, they have better chance to reproduce and pass on genes they are more fit
Fitness
Diminished in size because of disuse
Vestigial Structure
Similar structures, NOT because of common ancestor
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
