🗑
|
||||
| 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

| 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.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
