|
|
||||
|---|---|---|---|---|---|
| show | The evolution of a large number of related species from an unspecialized ancestral organism.
🗑
|
||||
| adaptive zone | show 🗑
|
||||
| show | Speciation that occurs when one population becomes geographically separated from the rest of the species and subsequently evolves.
🗑
|
||||
| allopolyploid | show 🗑
|
||||
| anagenesis | show 🗑
|
||||
| autopolyploid | show 🗑
|
||||
| background extinction | show 🗑
|
||||
| behavioral isolation | show 🗑
|
||||
| clade | show 🗑
|
||||
| cladogenesis | show 🗑
|
||||
| development | show 🗑
|
||||
| extinction | show 🗑
|
||||
| gradualism | show 🗑
|
||||
| show | reproduction between similar species is prevented because they live and breed in different habitats
🗑
|
||||
| show | A postzygotic reproductive isolating mechanism in which, although an interspecific hybrid is fertile and produces a second (F2) generation, the F2 has defects that prevent it from successfully reproducing.
🗑
|
||||
| hybrid inviability | show 🗑
|
||||
| hybrid sterility | show 🗑
|
||||
| show | An area of overlap between two closely related populations, subspecies, or species, in which interbreeding occurs.
🗑
|
||||
| show | Large-scale evolutionary change over long time spans.
🗑
|
||||
| mass extinction | show 🗑
|
||||
| show | A prezygotic reproductive isolating mechanism in which fusion of the gametes of two species is prevented by morphological or anatomical differences.
🗑
|
||||
| show | The small genetic changes a population undergoes.
🗑
|
||||
| show | Retention of juvenile or larval features in a sexually mature animal.
🗑
|
||||
| preadaptation | show 🗑
|
||||
| prezygotic barrier | show 🗑
|
||||
| punctuated equilibrium | show 🗑
|
||||
| reproductive isolating mechanisms | show 🗑
|
||||
| sexual reproduction | show 🗑
|
||||
| show | A type of natural selection that occurs when individuals of a species vary in their ability to compete for mates; individuals with reproductive advantages are selected over others of the same sex.
🗑
|
||||
| speciation | show 🗑
|
||||
| stasis | show 🗑
|
||||
| show | The evolution of a new species within the same geographical region as the parental species.
🗑
|
||||
| show | The synthesis of previous theories, especially of Mendelian genetics, with Darwin's theory of evolution by natural selection to formulate a comprehensive explanation of evolution; also called neo-Darwinism.
🗑
|
||||
| show | A prezygotic reproductive isolating mechanism in which genetic exchange is prevented between similar species because they reproduce at different times of the day, season, or year.
🗑

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.
