AND ANSWERS GRADED A+
✔✔Evolution - ✔✔_________ is the change in the inherited characteristics of biological
characteristics of populations over successive generations.
✔✔Natural Selection - ✔✔_____ _______ is the gradual process by which biological
traits become either more or less common in a population.
✔✔Heritable Traits - ✔✔Natural selection affects a population through what?
✔✔Natural Selection - ✔✔The following are necessary for what to occur?
1. Heritable variations exists in a population
2. The number of offspring that can be produced is greater than the number that are
produced
3. Not all individuals in a population are equally successful at survival and reproduction;
this differential success is at least partially due to different inherited traits in the different
individuals

model?
