|
Distributive Selection |
A sudden change in environment causing a population to split sometimes creating a new species |
|
|
Stabilizing Selection |
Genetic diversity decreases and the population begins to adapt a specific trait |
|
|
Directional Selection |
directional selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. |
|
|
Divergent Evolution |
Accumulation of traits in a population that might lead to a new species. |
|
|
Convergent Evolution |
Separate species gaining the same adaptations e.g. (wings, flippers) |
|
|
Homeostasis |
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
|
|
|
Homologous Structure |
when very different animals have bones that appear very similar in form or function and seem to be related |
|
|
Analogous Structure |
Body part in different species that is similar in function but not instructure that evolved in response to a similar environmental challenge |
