| Question | Answer |
|---|---|
| The process by which individuals are better adapted to their environment and are more likely to survive and reproduce is called? | Natural selection |
| Any difference between individuals of the same species is a | Variation |
| The time it takes for half of the atoms in a sample to decay is its | Half life |
| A well tested concept that explains a wide range of observation is a | Scientific theory |
| The theory that speices evolve quickly during short burst of time | Punctuated equilibria |
| Documentation of the milions of fossils scientists have collected over time is called | Fossil record |
| Unstable elements that decay or breakdown into different elements are | Radioactive elements |
| Similar structures that related species have inherited from common ancestors are called | Homologus structures |
| A hallow space left where the fossil has decayed or dissolved is called a | Mold |
| A process comparing the age of two fossils by their placement in the layers of sedimentary rock layers | Relative dating |
| Gradual changes in a species over time is called | Evolution |
| Fossils that are buried in sediments and actually changed to rocks are | Petrifed fossils |
| A trait that helps an organism survie and reproduce is a(n) | Adaptation |
| The theory that evolution occurs slowly but steadly is | Gradualism |
| A diagram thats shows how scientists think different groups of organisms are related is a | Branching trees |
| A process that test the radioactive materials within a fossil to tell its actual age ( also knows as absolute dating)is called | Radioactive dating |
| Preserved remains of an organism that lived in the past are | Fossils |
| When no member of the species is still alive its called | Extint |
| A copy of the shape of the organism that made is called a | Cast |
| This is a factor in natural selection as organisms attempt to survive using the same limited resources(food, shelter, mates..) | Competition |
| Evidence that related species had a common ancestor because of the way their bodies are anatomically constructed in similar ways | Homolougus structure |
| This factor in natural selection happens when there are more offspring than can possibly survive on given resources | Overpreduction |
