Document Summary

All living organisms adapt to their environments, which leads to increased survival/reproductive success: adaptations occur over many generations. Anything modified by evolution has a genetic component. Evolution selects individuals with genes that result in traits that help them survive/reproduce. These favorable traits are passed on, and such favorable traits are chosen based on the environment and time frame. * i. e. galapagos island finches (wide beak vs. average beak vs. narrow/long beak) All living organisms are adapted to their environment, and this adaptation takes many forms: structural modifications. Enhance survival and reproduction i. e. an orchid has a flower that looks like a female wasp, so male wasps try to reproduce with it and other orchids, thereby pollinating them: biochemical pathways. Development of metabolism or photosynthesis or respiration: behavioral adaptations. Increase survival and reproductive success i. e. learning to avoid predators or developing mating rituals in order to find strong/suitable mates.
