b. were descended from siliar birds in africa.
c. had become adapted to eating different diets.
3. Natural selection works on variation that originally came from:
a. adaptions to the environment.
b. asexual reproduction
c. changes in the number of individuals in a population
d. mutations of the DNA
4. A trait that allows organisms to survive and reproduce better than others without the trait in a specific environment is a:

1. Who published his own theory of evolution by natural selection about the same time as Charles Darwin?

2. Any inherited characteristic that increases an organisms chance of survival, like webbed feet, sharp claws, or speed is called an ___.

3. A giraffe that stretches its neck longer by reaching for food and then passes this long-necked trait on to offspring is an example of ____ of ____.

4. Another name for divergent evolution is _____.

5. On the Galapagos Islands, Darwin observed that the characteristics of many animals and plants: a) all looked alike. b) varied from island to island. c) were acquired through use.

6. Because of its similarities to artificial selection, Darwin referred to the "survival of the fittest" as: a) use it or lose it. b) natural selection. c) homologous structures. d) struggle for existence.

7. The idea that each living species has descended with changes from other species over time is called: a) descent with modification. b) struggle for existence. c) artificial selection. d) acquired traits.

8. An inherited characteristic that increases an organism ability to survive and reproduce in its specific environment is called: a) homologous structure. b) vestigial organ. c) adaption. d) speciation.

9. A human appendix, whale hipbones, and a skin’s legs are examples of: a) homologous structures. b) embryonic mates. c) vestigial organs.

Answer any that you know. I REALLY need help, thanks!
FaceFull, I’m loaded with TONS of other AP and preAP homework and I just need to get this out of the way. It’d be nice if you would help, thanks.
Aqua, thank you so much!! :)

QUIZ!!!!!!10points!!!!!!?

May 282010

Question 1 (Multiple Choice Worth 2 points)

Darwin visited the Galapagos Islands several times. He observed some very unusual species. One species of bird, the finch, interested him. He observed some differences in the finches living on different islands. The finches that lived on each island had a different beak. Some beaks were short some long. Some beaks looked straight while others curved. Darwin believed that each species of finch was related but had developed some special beak adaptations because there were different food sources on each island.

What is the main idea of this paragraph?

Finches on different islands have different beak structures which Darwin believed was related to what they ate.

Finches have different diets

Darwin believed that finches can live anywhere as long as their beak structure is well suited for the food supply.

Finches are picky eaters

I’m looking for help with the following multi-portion question. I’d really appreciate any answers/explanations you have. Thank you!

a) Explain the theory of evolution by natural selection as presented by Darwin.
b) Explain how each of the following relates to an aspect of evolution by natural selection.
i. Natural selection and the formation of insecticide-resistant insects or antibiotic resistant bacteria
ii. Speciation and isolation
