- Darwin’s view of the evolution of the giraffe wasdescribe at least one reason why Darwin was right and Lamarck was wrong when it came to explaining evolution, using giraffes to explain your reasoning.Briefly describe how observing beak sizes in finches before and after a drought in the Galapagos provides evidence for evolution. Meant to be a short answer like 4 sentences or so is great
- How did Darwin explain the data about the finches on the various Galapagos Islands? Group of answer choices 1: they must have all evolved on one island and then spread to others 2: they were not always finches, but evolved from some other birds 3: a bird with a long narrow beak probably ate seeds, which were hard to crack 4: they had evolved different beaks because of the different food sources on the islandsDarwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples? a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring. b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit. c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color. The turtles scurry toward the water,…Answer the following: This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? Explain in detail. (b) This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it? Explain in detail.
- According to Lamarck’s theory of evolution, organisms change during their lifetime to survive then pass these changes to their offspring. What supports the hypothesis of Lamarck? a. Webbed toes of ducks to quickly move through the water, retractile claws of carnivorous mammals to catch the prey, millipede producing awful smell for self-defense and evolution of short-necked to long-necked giraffe b. Evolution of short-necked to long-necked giraffe, webbed toes of ducks to quickly move through the water, disappearance of limbs in snakes and retractile claws of carnivorous mammals to catch the prey c. Rattlesnake producing venom against predators, jellyfish bioluminescence for intraspecific communication chameleons camouflage to hide from predators and millipede producing awful smell for self-defense d. Disappearance of limbs in snakes, chameleons camouflage to hide from predators, evolution of short-necked to long-necked giraffe and rattlesnake…Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. What experiment did he conduct to test this hypothesis? the breeding of finches O the breeding of pigeons the observation of humans the observation of dog breedsLook at the last sentence in Chapter 7 from the first edition of the Origin. It’s a remarkable sentence. Describe in your own words what Darwin is saying. Finally, it may not be a logical deduction, but to my imagination it is far more satisfactory to look at such instincts as the young cuckoo ejecting its foster-brothers,-ants making slaves, -the larvae of Ichneumonidae feeding within the live bodies of caterpillars,-not as specially endowed or created instincts, but as small consequences of one general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
- A skeptic of evolution asks the following question – “If humans evolved from monkeys, why are there still monkeys?” Use your understanding of primate evolution to explain to this individual why their view of primate evolution is skewed. Reference examples.One of Darwin’s finches, the medium ground finch (Geospiza fortis), is found on the small island of Daphne Major. These finches are seedeating birds. A major drought occurred on the island in 1977. Following the drought, the average beak size of medium ground finches had increased about 3%–4%. Why might a drought lead to an evolutionary change in beak size? Propose a hypothesis and explain how you could go about testing it.Explain how giraffe’s neck gets longer and longer using the theories of Darwin and Lamarck
