| The theory that species evolved by keeping the traits that parents aquire or develop during their lives. | LAMARACK's HYPOTHESIS of AQUIRED CHARACTERISTICS |
| The idea that organisms best suited (most fit) to their environment are more likely to survive is called | NATURAL SELECTION |
| Variations (differences) in populations can add.... | NEW SPECIES |
| Change in inherited charactersitics or change in hereditary features over time is called | EVOLUTION |
| Organisms that are similiar (the same) and can successfully reproduce called... | SPECIES |
| A difference in an inherited trait of an organism that may lead to a new species is called a | VARIATION |
| A model of RAPID EVOLUTION is | PUNCTUATED EQUILIBRIUM |
| Model of evolution showing SLOW CHANGE over time is | GRADUALISM |
| Variations result from | PERMANENT MUTATIONS |
| Any variation that makes an individual better suited to survive (such as a white rabbit in a snowy habitat is called | ADAPTATION |
| Theory of Evolution by Natural Selection is the | THEORY OF EVOLUTION by DARWIN |
