Biological Evolution
| Question | Answer |
|---|---|
| This part of natural selection is when an organism has an adaptation that allows it to be successful, survive, reproduce and create more of its kind. | selection |
| This is a trait that is NOT passed down through genetics, but is either learned or developed by environmental changes.(Like Snoopy who injures his right hand and learns how to write with his left.) | aquired trait |
| The white feathers of a snow owl allows it to camouflage more successfully in the arctic environments in which it lives. What does this best describe? | adaptation |
| This is when a new species of fish evolves from an already existing species of fish due to isolation and changes in the environment. | speciation |
| Differences in species because of changes in their genetic make-up is called? | variation |
| When an ecosystem has a high __________________ (many different kinds of species) , this is a sign that is very rich and successful. | biodiversity |
| A physical structure that was once functional, but overtime became reduced and no longer used is called (like the unused bone structure found in the skeleton of a whale) ? | vestigial organ |
| The geologic time scale is a record of Earth's history. Scientists use ___________ to show the link between geological evolution and biological evolution. | fossils |
| Fossils that help show similarties between ancestor fossils and modern fossils are called? | Transitional fossils |
| Another name for genetic material is? | DNA |
| DNA can be used to support biological evolution by showing that organisms with similar DNA sequences may have? | Common Ancestry |
| Scientists use this to show that certain animals look very similar in their early developmental stages. | Embryological similarity |
| This is a structure with similar traits found in different organisms NOT due to common ancestry, but due to similarities of how the organism adapted to their environment. | Analogous Structure |
| This is a structure with similar traits found in different organism because of common ancestry. | homologous Structure |
| These cylinders of ice are what scientist use to study past climate. | ice cores |
| This is the type of fossil that scientists use to determine the relative age of a rock layer. A trilobite is an example. | index fossil |
| Radiometric dating, Parent vs. Daughter Material, and Isotope are all terms that describe.......? | absolute dating |
| This is the isotope used to find the absolute age of fossils. Remember, fossils are ancient remains of LIVING THINGS. | carbon -14 |
| When scientist identify the younger rocks on top and the older rocks on the bottom, this method is called......? | law of superposition |
| The theory that Earth's lithosphere is divided into sections and moves upon the asthenosphere. | plate tectonics |
