Darwin also studied finches [small birds]. Each island had a different species of finch. Later, Darwin came to the conclusion that all were descended from a single species of finch. On each island, the finches had diverged and become slightly different.” Item 2 “Charles Darwin was surprised to learn the local people could tell by looking at a tortoise which island it came from. Later, Darwin came to believe that the different tortoises all descended [came from] one species of tortoise.”” Item 3 Words to know Mutation: a DNA error Unfavorable: not helpful Favorable: helpful Item 4 Foldable or Cornell notes? Decide if you want your pg. 59 to be a foldable or Cornell notes. “Nature is neither kind nor cruel, but indifferent.” -Richard Dawkins To survive & reproduce, animals need… -Food -Water -Shelter -Territory -Mates Must engage in competition with other animals (same species or not) in order to get those things. Charles Darwin (1809-1882) Traveled to the Galapagos Islands Noticed small differences in the tortoises and finches on each island Developed the Theory of Natural Selection: favorable traits become more common over time, while unfavorable traits decrease Also called, survival of the fittest 1. DNA mutates and makes a new trait. 2. Favorable mutations join the group of favorable traits for that species. 3. Animals with favorable traits reproduce & pass on “good genes.” Mutations Started with 1 species of finch. Different islands have different food. Birds with favorable beak structure mutations caught and ate food, survived, & reproduced. The mutated beak genes became the norm. New species of finches became present. Brainpop: Natural Selection • Watch it 2 times. • Think about the information in the video and in your notes. • Write 5 sentences to answer these questions (pg. 58) • What is natural selection? • What happens to animals because of natural selection? • What does it mean to be fit for an environment, compared to not fit for an environment? • Can you give an example of natural selection? (i.e. 2 fish in a lake, 2 monkeys in a jungle) • Include a colored picture Brainpop: Natural Selection • Watch it 1-2 times. • Think about the information in the video and in your notes. Left Side Activity (poem/song lyrics, comic w/ summary, script for a kids show, etc.) (pg. 58) Must cover the following information: • What is natural selection? • What happens to animals because of natural selection? • What does it mean to be fit for an environment, compared to not fit for an environment? • Can you give an example of natural selection?
