|---|---|---|---|---|---|
| Common ancestry | between organisms of different species arises during speciation, in which new species are established from a single ancestral population.
🗑
|
||||
| Fossil record | is life's evolutionary epic that unfolded over four billion years as environmental conditions and genetic potential interacted in accordance with natural selection.
🗑
|
||||
| Biogeography | study of the distribution of plants and animals on Earth.
🗑
|
||||
| Homology | similarity in sequence of a protein or nucleic acid between organisms of the same or different species.
🗑
|
||||
| Anatomical homology | similarities between the structure of two organisms
🗑
|
||||
| Molecular homology | Similarities among organisms at the molecular level due to a shared ancestry.
🗑
|

| Developmental homology | is recognized in embryos. Two different organisms can have a common embryonic trait, say gill pouches or a tail, but in some of those organisms those gills and tails are lost.
🗑
|
||||
| Genome map | a record of the entire genome of an organism, consisting of correctly ordered gene maps.
🗑
|
||||
| DNA sequence | is the process of determining the precise order of nucleotides within a DNA molecule.
🗑
|
||||
| Taxonomic | The classification of organisms in an ordered system that indicates natural relationships.
🗑
|
||||
| Phylogenic | the evolution of a genetically related group of organisms as distinguished from the development of the individual organism
🗑
|
||||
| Offspring | the young of an animal or plant
🗑

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.
