Evolution Flashcards
idea that species change over time
Evolution
differences among individuals within a species group
Variation
ability to conform to the environment
Adaptation
If these individuals survive, then they have more chance to reproduce and pass on their genes
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
2 species evolving complementary structures because of close interaction
Coevolution
evolution that occurs in short bursts, followed by periods of no evolution (Looking at graphs)
Punctuated Equilibrium
Evolution that occurs in consistent small changes over time
Gradualism
