Question
Given the evolutionary history of the islands, does the "twig" phenotype on each island represent divergent or convergent evolution (divergent = shared through common ancestry, convergent = independent evolution of superficially similar traits). Why? 4. What are two other mechanisms that can cause adaptive radiations? 5. What do all three mechanisms that cause adaptive radiations to occur have in common? Fossils The fossil record provides important evidence for evolution because fossils give biologists a picture of the past. However, like all types of evidence, there are different biases that can occur when using fossil evidence that one should be aware of. Please answer questions 6-10 in reference to what you read, watched, and heard about in class relating to fossils. 6. What are the four basic types of fossils? 7. What types of habitats would be biased to produce MORE fossils compared to other habitats?Explanation / Answer
3) The twig phenotype of lizard anoles of each islands represent convergent evolution.The twig anoles exists in one island will not be of the same species or closely related to the twig anoles of another island even if they are looking similar. There are two evolution occurs naturally on anoles lizard: divergent and convergent evolution. The variations in lizards resulting in the each evolution is due to random mutation and recombination in the genetic sequences.
4) Natural selection and genetic drift are the mechanisms that leads to adaptive radiations. Natural selection results an evolutionary change in large population whereas genetic drift as few.
5) All the mechanisms have common effect that each process results in the change in genetic structure.
6) There are four types fossils based on morphology which includes:
