Decker Biology B-1
Unit test 2 Evolution
| Question | Answer |
|---|---|
| a term for a group of similar organisms that can reproduce and produce fertile offspring. | species |
| the difference in the physical traits of an individual from those of other individuals in a group | variation |
| Over time, adaptations can led populations to experience | genetic changes |
| What did Charles Darwin observe in finch populations on the Galapagos Islands off the coast of South America? | different species on different islands |
| What did Charles Darwin learn from the fossils of a giant armadillo that he found in Argentina? | modern animals may be related to fossilized organisms. |
| The development by scientists of a new color of a rose is the result of > | artificial selection |
| In natural selection, the selective agent is the | environment |
| All the rabbits living in a particular area would be an example of a | population |
| A bird that can easily outcompete for food that can produce many eggs has a high | fitness |
| Which of the following is an example of a vestigial structure | the wings of an ostrich |
| What is suggested by the similarity of early embryos of different species of vertebrates | evolution from a distant common ancestor |
| Some organisms that share a common ancestor have features that have different functions, but similar structures | homologous structure |
| If an organism has a vestigial structure, that structure likely once had a function in a | early ancestor |
| Two organisms that are closely related would have | very similar DNA sequences |
| Evolution is considered to be one of the most important theories in science because | it unites the fields of biology, geology, chemistry and ecology |
| Protein sequences in one organism that resemble those o another suggest a | shared ancestry |
| What is the term for a feature that allows an organism to survive better in its environment | adaptation |
| All the individuals of a species that live in a particular area are called a | population |
| The remnant of a organ that had a function in an early ancestor is known as a | vestigial structure |
| The hind leg bones shown in the whale are examples of | vestigial structure |
| What is the process in which humans breed organisms for certain traits. | artificial selection |
| The individuals that are adapted to their environment will survive and produce | more offspring |
| Fossil evidence shows that structures considered vestigial in living organisms | were useful in their ancestors. |
