Mimicry
Cryptic coloration
Camouflage, makes an organism difficult to spot
Microevolution
Evolutionary change below the species level
Evolution
The change in a population’s inherited traits from generation to generation
Population on genetics
The study of how populations change genetically over time.
Macroevolution
The broad pattern of evolution above the species level
Aposematic coloration
Bright warning colors in animals with a chemical defense
Speciation
The origin of new species in evolution
Natural selection
The evolutionary process by which favorable traits that are heritable become more common in successive generations.
Mutations
Change in the nucleotide sequence of DNA
Reproductive isolation
The existence of biological factors that impede members of two species from interbreeding and producing viable, fertile offspring
Mimicry
Ability of an animal to look like another more harmful animal
Species
A group whose members possess similar anatomical characteristics and have the ability to interbreed
Evolutionary adaptations
Inherited traits further gave developed though evolution
Gene flow
Genetic additions to and or subtractions from a population resulting from the movement of fertile individuals
Prezygotic barriers
Before the zygote block fertilization from occuring
Batesian Mimicry
Species mimic the appearance of an unpalatable or harmful
Polyploidy
A chromosomal alteration in which the organism possesses more than two complete chromosomes sets
Gradualism
The slow, gradual steps of change
Geographic Variation
Differences between the gene pools of separate populations or population subgroups
Habitat isolation
2 species that occupy different habitats within the same area may encounter each other rarely
Mullerian mimicry
Two or more unpalatable species resemble each other
Paedomorphosis
The retention in an adult organism of the juvenile features of its evolutionary ancestors
Artificial selection
Cline
A graded change in a trait along a geographic axis
Temporal isolation example
North American skunks
