Evolution Test Review

Matching Match the term with the corresponding definition variation slight differences between individuals of the same species mutation random change in the DNA when it is being copied during reproduction; one to have variation in species evolution change in species over time natural selection organisms that are best suited to the environment will survive and reproduce adaptation the result of a variation that helps an organism survive Fill in the blanks with the appropriate word or phrase. Click on the blank to see the word bank. A group of organisms have genetic variationamong the population as a result of sexual reproduction on genetic and mutationsSome variations for traits are better for their new environment increasing an organism's fitness. This variation would be considered an adaptation because it helps the organism survive.Organisms with the better traits survive and reproduceto pass the trait on in their DNA In natural selection humans choose adaptations that help the species survive. True False Natural selection results in adaptations that allow the fittest organisms to survive and reproduce. True False Artificial Selection does not always enhance survival of a species. True False Artificial selection occurs when the environment determines which traits are good and bad. True False Sort the examples below into the appropriate column Read each example and determine if it belongs under Natural Selection or Artificial Selection. Then drag and drop it under the appropriate heading below. Natural Selection A population of lizards slowly evolve longer legs as shorter leg lizards die off due to fire ant bites. Animals that can reach high vegetation survive and reproduce in an environment where there are few low lying plants Orange beetles in a rainforest get eaten by predators more often than green beetles Artificial Selection Farmers cut down all short and low growing corn only allowing the tallest and strongest to survive and use those seeds for further crops Scientist select golden retrievers with the softest coats and breed them to produce that trait in their offspring Fossil Layers Label the oldest and youngest layer with the words "Youngest" and "Oldest". Make sure to spell it correctly and capitalize the first letter or it will be marked incorrect. Youngest Oldest In the fossil picture above, compare fossils in the bottom layer to the fossils in the top 3 layers. What best explains what happened in that area over time? There was land at one time and then it became water. The was water and then it became land
