|
Definition
| No, therefore the competition for energy in order to survive will be created. |
|
|
Term
| When a trait changes does this become a permanent adjustment? |
|
Definition
| No, frequencies vary over time and change from time to time. |
|
|
Term
|
Definition

Term
| What is natural selection? |
|
Definition
| occurs when individuals with certain allels and traits produce the most offspring in a population...Evolution by natural selection changes only the characteristics of the population. |
|
|
Term
| 4 postulates of Natural Selection(4statements Dawin said) |
|
Definition
1)Individual organism in a population vary in traits.
2) Some variations are passed on to offsprings
3) Only a subset of offspring will survive
4) The survivors have traits that let them prevail environmental changes. |
