Unit 10 Evolution

5. An inherited trait that allows an organism to better survive in its environment.
8. The competition to reproduce within a species.
10. Similar anatomical structures in different organisms that show common ancestry, though they may serve different functions.
12. Type of isolation cause when natural barriers prevent populations from reproducing.
13. Organisms with advantageous traits are more likely to survive and reproduce, causing the species traits to evolve.
15. Type of evidence that comes when comparing DNA or proteins of one species to another, more similarities are found in species that are more closely related.
16. Type of Isolation caused by behavioral or physical trait barriers prevent populations from reproducing.
18. Interactions within a species or between different species in an environment for limited resources (such as water, food, or habitat).

1. Formation of a new species.
2. Group that can reproduce with each other and produce fertile offspring.
3. Aspects of the environment put selective pressure on organisms. These may include food sources, predators, habitat changes/loss, and natural disasters.
4. Scientific classification of organisms.
5. Humans select traits they find helpful and breed animals and plants for those traits.
6. Statements or models that have been tested and confirmed.
7. Structures that were used by and inherited from a common ancestor, but have lost their purpose over time and no longer have a function.
9. Change in a species over time
11. A British Naturalist that wrote “The Origin of Species” and studied many species in the Galapagos Islands, including finches.
14. Structures that evolved separately in non-related organisms by natural selection in similar environments.
17. An ancestor that two or more species share
