RAWR

1. Species exist in population
Individuals in a population vary anatomically, physically and behaviorally.
2. Variation in individuals is inherited
Where did my prey go?
Variation in a population is from mutation in genes, gene flow and sexual reproduction
3. Individuals in population reproduce
Mates are chosen based on biological factors(i.e. how they look, act, etc.)
4. Competition
THATS MY TREE!!!!!!
Resources are limited(i.e. food, shelter from predator, mates, etc.)
Individuals with traits that allow them to survive and reproduce pass on their genes
No!! Where did that cow go? My leader will kill me.
Safe
5. Survival
6. Over time environment can shift
7. Evolution is the change in traits over time
There are too many predators we must live here now
As habits change some variations in a population allow some organisms to survive and reproduce, passing their successful traits(genes), other individuals in the population die
Over time species change due to environmental changes and the individuals most suited for the environment survive to reproduce
