Evolutionary History
| Question | Answer |
|---|---|
| To classify based on scientific examination | diagnose |
| Graph that shows how the characteristics or values are distributed within a group. | histogram |
| A related organism from a previous generation. | ancestor |
| Scientist who studies fossils to understand the ancient history of life on Earth. | paleontologist |
| Time that spans the history of Earth, from the very first cellular life to the present. | evolutionary time |
| Body Structure in two or more species that features the same parts. | shared structure |
| Everything (living and nonliving) that surrounds an organism. | environment |
| When something stays mostly the same over time. | stability |
| Group of individuals born and living at about the same time. | generation |
| Sharing a common ancestor population. | related |
| An organism's arm, leg, or wing. | limb |
| Part of an organism (for example, one or more bones). | body structure |
| Specific characteristic of an individual organism. | trait |
| Process by which the traits in a population changes over many generations. | natural selection |
| Process by which species adapt to environmental changes over a very long time. | evolution |
| A group of the same type of organism living in the same area. | population |
| Something that makes it likely that an individual will survive in an environment. | adaptive trait |
| Process by which one population evolves into two or more different species. | speciation |
| Evidence of life from the past, such as fossilized bones, footprints, or leaf prints. | fossil |
| Organisms of the same kind that don't reproduce with other organisms. | species |
| Living things, such as plants, animals, and bacteria. | organisms |
| More recent species that evolved from an ancestor population. | descendant species |
| A random change to a gene that sometimes results in a new trait. | mutation |
| Having died out completely and no longer alive anywhere on Earth. | extinct |
| To receive from a parent. | inherit |
| Older population from which two or more newer species descended. | common ancestor |
| __________ traits most commonly change when the environment changes. | adaptive |
| T or F - Both 'Natural Selection' & 'Evolution' depend heavily on mutations. | true |
| T or F - Scientists specifically study nymphs to help understand how different organisms are related. | false |
| T or F - Large changes in body structure within a population take place in small amounts of time. | false |
| T or F - Shared structures can be things like glands and organs. | true |
| T or F - A changing environment can result in a stable population. | false |
| T or F - More similarities between organisms indicates the more distantly related they are. | false |
| T or F - Plants & animals have some shared structures. | true |
