Evolution
Mechanism
-
Migration- AKA gene flow, movement of individuals and their genetic information from one population to another
Genetic Draft- Unlike natural selection, an advantageous trait is not necessarily being selected for
Natural selection- occurs because their is variation, heredity, and the environment cannot sustain unlimited population growth
Microevolution
A change in gene frequency within a population.
Occurs over short periods of time like from one generation to the next.
-
-
Homologous
Character in different organisms that are similar because they were inherited from a common ancestor that also had that character
Analogous
have a separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them in a similar way
