Term
The Theorys of Natural Selection are? |
|
Definition
- Every living thing exhipts variation.
- Pop. size increases faster than food supply. (malfis)
- Because each pop. has more individuals than can survive, there is competition for resources.
- Those individuals that have favorable traits will have an advantage and are more likly to survive.
- The environmenal context determines if a trait is bennificial. good one setting, liablity another.
- These traits are inherited and therby passed to next generations.
- Over long periods of time theose succesful traits acuumlate in later generations, in timecan lead to new species.
