|---|---|---|
| 1 | the idea that omly the organisms best suited for their environment will survive and reproduce | 35 sets |
| 2 | the idea that only the organisms best suited for their environment will survive and reproduce | 32 sets |
| 3 | evolutionary process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common | 24 sets |
| 4 | natural selection of certain varieties, change in proportion of those varieties in the next generation (differential reproduction), extinction of poorly adapted forms | 12 sets |
| 5 | a process that supposedly results in the survival of the organisms that are best suited for their environment | 10 sets |
| 6 | heritable variation in traits influencing survival (ego reproduction) exists; therefore some individuals contribute more offspring to the next generation than others (differential survival and reproduction); heritable traits of these successful individuals become increasingly more abundant in the population over time; ergo avg. characteristics of the population change over time as the population evolves | 10 sets |
| 7 | darwin | 8 sets |
| 8 | the traits that make an organism more successful are passed on to offspring | 8 sets |
| 9 | organisms that have certain favorable traits are better able to survive and reproduce successfully than organisms that lack these traits | 7 sets |
| 10 | a theory that explains the process of evolution. it states that inherited characteristics that give an organism a reproductive or survival advantage are passed on more often to future generations than other inherited characteristics. | 5 sets |
| 11 | the theory that states organisms best suited for their environment will survive and pass their favorable traits on to their offspring | 5 sets |
| 12 | populations grow exponentially and exceed their resources. (malthus 17898) overpopulation results in competition and struggle for survival. in every population, variation among individuals leads to an unequal chance for survival and reproduction. | 4 sets |
| 13 | better adapted organisms are more likely to survive and become the parents of the next generation. result: population changes over time; frequency of favorable traits increases in successive generations while less favorable traits become scarce or disappear. | 4 sets |
| 14 | organisms better adapted to their environment will survive and reproduce-"survival of the fittest". | 4 sets |
| 15 | unequal survival and reproduction that results from the presence or absense of particular traits that allow the organisms to better survive in it's environment | 4 sets |
| 16 | the idea that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations. | 4 sets |

| 38 | the idea that the environment destroys organisms that are less able than others to live in the environment 1. more young are produced than can remain alive; some will die 2. individuals in a species compete with each other for available resources 3. some individuals are better able to compete 4. the individuals with the best characteristics to obtain the resources they need will survive 5. those individuals that reproduce pass on their traits 6. only the organisms best suited to survive will be able to pass on their traits | 2 sets |
| 39 | tenets of this theory include --populations tend to overpopulate --overpopulation results in competition and struggle for existence --in any population, there is variation and an unequal ability of individuals to survive and reproduce --only the best-fit individuals survive and pass traits to offspring --evolution occurs as advantageous traits accumulate in a population | 2 sets |
| 40 | process that supposedly results in the survival of organisms that are best suited for their environment | 2 sets |
| 41 | overproduction- species produce more offspring than the environment can support variation- species produce more offspring with characteristics that differ; different varieties exist selection- environment selects traits that make it easier for an organism to survive and reproduce adaptation- trait that improves survival will become more common; overtime, the amount of organisms with advantageous traits will increase | 2 sets |
| 42 | predicts that over time, the number of individuals that carry advantageous traits will increase in a population) | 2 sets |
| 43 | mutations create new traits. if a trait is beneficial, the better organism will reproduce and pass it off to its offspring. if not, the organism dies off. | 2 sets |
