Storyboard-Text
- 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
