Pinta island vegetation12/25/2023 ![]() The Pinta Island turtles possess necks and shell curvature somewhere in between the Hood and Isabela turtles. One would predict that vegetation exists close to the ground, as well as in some higher reaching areas. The domed shell will not restrict their ability to eat food low and they do not need to reach for it. Why did you choose the island you did? Which island do you think has sparse vegetation that is hard to reach? Pinta Island Hood Island What would you predict the vegetation and rainfall are like on Pinta Island? The fact that the tortoises have short necks & domed shells suggest that Isabela island has vegetation low to the ground. Which island do you think this is? Isabela Island Hood Island EXPLAIN your answer. On one island plants grow very close to the ground. Beaks adapted according to function (grasphing, probing or crushing bills) based on the food the finches were eating (fruit, insects, cactus or seeds).ĭarwin’s Theory of Evolution(Chapter 15-1 and 15-2 pp 368-377) Tortoises eat plants. ![]() The beaks of the Galapagos finches adapted to a variety of foods. What might this tell you about the eating habits of the birds on different islands? Explain your answer. On the Galapagos Islands, Darwin discovered birds with differently shaped beaks. This provided the long time span Darwin thought was needed for changes in living things Explain how Hutton’s and Lyell’s ideas about the formation of the Earth influenced Darwin’s ideas about Evolution. Hutton and Lyell also proposed that Earth was millions of years old. This helped Darwin’s idea that the living things change. JAMES HUTTON Aĭarwin’s Theory of Evolution(Chapter 15-1 and 15-2 pp 368-377) Hutton and Lyell proposed that Earth had changed. Organisms are adapted to their environments.ĭarwin’s Theory of Evolution(Chapter 15-1 and 15-2 pp 368-377) E C B D MATCH THE SCIENTIST with his contribution _ proposed that Earth was shaped by geological forces that took place over millions of years _ proposed that organisms acquired or lost traits during their lifetime by selective use or disuse of organs _ predicted that the human population will grow faster than the space and food needed to sustain it _ stressed that scientists can explain past events in terms of processes occurring they can observe happening now _ proposed a hypothesis to explain how living things change over time A. Acquired characteristics can be inherited. All species were descended from other species B. Which of the following ideas, proposed by Lamarck, was later found to be incorrect? A. Giraffes just started out with long necks and haven’t changed. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on. Natural variation in the population produces some longer and some shorter-necked giraffes and longer necked giraffes can reach food more easily. Long-necked giraffes eat more grass than short necked giraffes so their necks grow longer. were acquired through use Which of the following best describes how LAMARCK would explain giraffes with long necks?
