🗑
|
||||
| One of the adaptations Darwin observed was: | birds different shaped beaks
🗑
|
||||
| Many fossil vertebrates are similar to living vertebrates because: | they have a common ancestor
🗑
|
||||
| Artificial selection | breeding animals and plants to produce offspring with desired traits
🗑
|
||||
| Natural selection | individuals with successful traits produce more offspring and are more likely to pass those traits to the next generation
🗑
|
||||
| gene pool | all the alleles of all the individuals of a given population
🗑
|
||||
| Biological fitness | a measure of an individuals contribution to the gene pool of the next generation
🗑
|
||||
| vestigial structures | remnants of structures that were important at one time but have no clear function today
🗑
|
||||
| Genetic drift | a change in the gene pool due to chance
🗑
|
||||
| Darwin's theory of evolution is based on: | variation and natural selection
🗑
|
||||
| Genetic drift changes occur because of: | chance
🗑
|
||||

🗑
|
||||
| A genus is composed of a number of related: | Species
🗑
|
||||
| Cladogram | An analysis of derived characters
🗑

| Organisms in the domains Bacteria and Archaea were previously grouped in the kingdom: | Monera
🗑
|
||||
| Hardy-Weinberg equilibrium | allele frequencies in a population will remain constant when populations do not undergo changes to their gene pools
🗑
|
||||
| microevolution | a generation-to-generation change in the frequencies of alleles in a population
🗑
|
||||

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.
