Species | A group of organisms that can successfully reproduce with each other |
Evolution | The slow inherited change of a species over many many generations |
Natural selection | Darwin's explanation of how evolution happens based on four ideas: overproduction, variation, adaptation, and spread of successful variations |
Variation | Differences in an inherited trait among members of a species |
Adaptation | A variation that helps an organism to survive better than an organism without the variation |
Gradualism | Explanation of how fast evolution happens and how new species evolve; gradualism says new species evolve slowly by gradual change |
Punctuated equilibrium | Explanation of how fast evolution happens and how new species evolve; punctuated equilibrium says new species evolve "quickly" due to small genetic mutations and/or rapid environmental change, then stay the same for long periods of time |
