|---|---|---|---|---|---|
| abiogenesis | idea that life originates spontaneously from non-living matter.
🗑
|
||||
| adaptation | process of becoming adapted to an environment; an anatomical structure, physiological process, or behavioral trait that improves an organism's likelihood of survival and reproduction
🗑
|
||||
| biogenesis | idea that life arises only from other living organisms
🗑
|
||||
| evolution | Changes that occur over time to organisms. This can cause the change of genetic information. Certain traits can be lost
🗑
|
||||
| absolute dating | the process of determining an approximate age for an archaeological or paleontological site or artifact.
🗑
|
||||
| biochemical comparison | organisms with similar biochemical composition suggest that they have developed from a more primitive common ancestor.
🗑
|
||||
| carbon dating | radiometric dating method that uses the naturally occurring radioisotope (14-C) to estimate the age of materials up to about 58,000 to 62,000 years
🗑
|
||||
| coevolution | The mutual influence on the evolution of two different species interacting with each other and reciprocally influencing each other's adaptations
🗑
|
||||
| evolution | All the changes that have transformed life on Earth from its earliest beginnings to the diversity that characterizes it today
🗑
|
||||
| fossil | Remnants of once existing organisms
🗑
|
||||
| geographic isolation | occurs when biological populations of the same species become isolated from each other to an extent that prevents or interferes with genetic interchange.
🗑
|
||||
| natural selection | process by which populations change in response to their environment leave more offspring
🗑
|
||||
| Pesticide resistance | the adaptation of pest species targeted by a pesticide resulting in decreased susceptibility to that chemical.
🗑
|
||||
| pollination | The act of transferring pollen from the anther to the stamen of the plant.
🗑
|
||||
| relative dating | the science determining the relative order of past events, without necessarily determining their absolute age.
🗑
|
||||
| reproductive isolation | Various structural, behavioral, and biochemical features can prevent interbreeding and thus reproductively isolating populations as distinct species.
🗑
|
||||
| speciation | process by which new species are formed.
🗑
|
||||
| vestigial organ | A type of homologous structure that is rudimentary and of marginal or no use to the organism
🗑
|
||||
| binomial nomenclature | formal system of naming species of living things by giving each a name composed of two parts
🗑
|
||||
| cladogram | A branching diagram showing the relationship between a number of species.
🗑
|
||||
| classification | The arrangement of animals and plants in taxonomic groups according to their observed similarities.
🗑
|
||||
| embryology | The branch of biology and medicine concerned with the study of embryos and their development.
🗑
|
||||
| evolution | All the changes that have transformed life on Earth from its earliest beginnings to the diversity that characterizes it today
🗑

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.
