More organisms are born than can survive
All organisms are exactly the same as other organisms of their species
There is variation of inherited traits amongst organisms
Some organisms have a higher level of fitness than others in their environment
How physically strong it is
How much it changes to fit its environment within its life
How well it can survive within its environment
Where it fits in on the food chain

Natural selection

Artificial Selection
Cruelty to animals
The one found in A

All would be the same age
Long neck giraffes gettin food frm a tall tree
White tail deer living in a snowy area
Species living in different locations
Changes in the inherited characteristics of a population over time
Had very large beaks
Beaks formed to eat different foods
Ancestors had different shapes of beaks
Had small beaks
Any reproductive barrier that keeps 2 populations from interbreeding
Seperation of a populations due to geographic change
A change in the gene pool due to chance
Populations tend to overpopulate
Not all individuals are the same
Resources in an environment are limited
Only the strong survive
Similar structures with identical functions shared by distantly related species that are a result from natural selection in similar environments, but that evolved independently.
Structures which evolved from the same structure within a common ancestor; may or may not serve the same function.
Structures which are reduced and perhaps even nonfunctional in one species but homologous to functional structures in a closely related species.
Any vital structure used by many different species.
