| How is natural selection related to the process of evolution? | Natural selection is the survival and reproduction of organisms with particular traits. Over many generations, natural selection leads to a change in the genetic characteristics of a population. This change is called evolution. |
| Evolution | The total amount of changes in a population over time from one generation to the next. |
| Give 3 pieces of evidence supporting the theory of evolution. | fossil evidence, similar embryonic development, homologous structures (similar in structure but have different function) |
| Explain what an adaptation is. | the process of becoming adapted to an environment; an anatomical, physiological, or behavioral change that improves a population’s ability to survive. |
| Give three examples of adaptation | thicker fur, resistance to a cleaner, longer beak |
| Coevolution | When two species interact with each other for long periods of time and evolve to depend on each other for survival |
| Examples of Coevoluion | humans and gut microbes, legumes and microbes (bacteria), honeycreeper(Hawaiian Bird) and Blue opelu (flower), bees and flower, ants and aphids, hummingbirds and flowers |
| Different organisms that have evolved resistance. | E coli (bacteria) and insects |
| How a population of insects could become resistant to pesticides. | Their body can break down the chemical and use it in another way. |
| Why is it so awful that human overuse antibiotics? | Bacteria that harm us are becoming resistant to the drugs humans have developed to control them. |
