|---|---|---|---|---|---|
| Divergent Evolution | species that were once a common ancestor diverge, or become increasingly different.
🗑
|
||||
| Cladogram | Shows particular characters that are either present, or not present, in the organisms being compared.
🗑
|
||||
| Geographic Isolation | A new species evolves because a physical barrier separated the population . over time, the divided populations may no longer interbreed, even if reunited.
🗑
|
||||
| Adaptive Radiation | when an ancestral species evolves into an array of species to fit a number of diverse habitats. is more common on the islands.
🗑
|
||||
| Homologous Structures | Structural features with a common evolutionary origin
🗑
|
||||
| Vestigial Structure | A body structure in a present-day organism that no longer serves its original purpose, but was probably useful to an ancestor.
🗑
|
||||
| Camouflage | Adaption to help an organism blend with its surroundings.
🗑
|
||||
| Analogous Structure | The body parts of organisms that do not have a common evolutionary origin but are similar in function
🗑
|
||||
| Convergent Evolution | Unrelated species occupy similar environments and evolve similar traits.
🗑
|
||||
| Mimicry | One species physically resembles another
🗑
|
||||
| Adaption | A structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce off springs.
🗑
|
||||
| Reproductive Isolation | Formerly interbreeding organisms can no longer mate and produce offsprings.
🗑
|
||||
| Punctuated Equilibrium | hypothesis that speciation occurs relatively quickly, in rapid bursts, with long periods or genetic equilibrium in between.
🗑

||||
| Gene pool | all the allels of a populations genes
Example.. Bb
🗑
|
||||
| Mutation | any change or random error in the dna sequence
🗑
|
||||
| Artificial Selection | involves people taking charge of selection to produce new, better varieties or various species. manipulate breeding to produce more desirable offspring
🗑
|
||||
| Natural Selection | any advantage that allows an organism yo get more food, survive and reproduce . the organisms best suited to survive in their environment have a greater chance or passing their traits on the next generation
🗑
|
||||
| Evolution | The gradual change in a species over time. CANNOT happen to an individual organism
🗑
