21
Q

A

When humans breed organisms for select traits

22
Q

For natural selection to happen you need….

A

1) Individuals very in form, function, and behavior
2) Adaptive Environmentally effected traits
* Organisms that do well in certain environments
3) Out come of differences are in survival and “reproduction”
* More fit more likely to survive & have offspring
4) Leads to a better fit with prevailing environmental conditions
* Weak ones die out & strong stay, means organisms better suited for their environment.
