1. Evolution
Ie- Change over Time

2. Founder
Charles Darwin- 1859

3. Strongest will Survive
“Adapt to your environment”

4. Darwin’s Evidence
Galapagos Islands- geographically isolated islands off the coast of Ecuador

7. But the real evidence for Darwin was
The Finches
their Beaks were adapted to the food source on their specific island

8. Specific Vocabulary

9. Natural Selection-happens over time the strongest survive to reproduce
(animals that are best suited to their environment will survive and reproduce)

10. Artificial Selection- Specific breeding done to create specific species
In Plants
and in Animals

11. Evidence for Evolution
Darwin’s Reasoning
Evidence for Evolution

12. Overproduction
Animals like the sea turtle overproduce so that the strongest will survive to reproduce and carry on the species.

13. Variation
Animals come in a variety of sizes and colors so that the ones with the best traits pass on those traits to their offspring

14. Adaptation
any inherited trait that give a specific animal an advantage in its environment

15. Selection
Natural or artificial

16. The evolution of a new species from an existing species
Speciation
The evolution of a new species from an existing species

17. Isolation
Isolation in a remote area like an Island can cause a species to change to fit the environment and food source

18. What can lead to the changes

19. More Evidence

20. Organs found in the body that are no longer needed (ie. appendix)
Vestigal Organs
Organs found in the body that are no longer needed (ie. appendix)

21. Homologus Structures
Same on different animals
bone structure of hands

22. So then What?

23. Competition leads to species changing over time and ensuring the
survival of the species through food webs
and chains

24. Population Density- the amount of animals
of a species in a particular area
