- Explain how giraffe’s neck gets longer and longer using the theories of Darwin and LamarckCharles Darwin and Jean Baptide de Lamarck have different ideas of explaining evolution. Describe how each of them explained the evolution of long necks of giraffes. Justify whose idea is more acceptable in science community.describe at least one reason why Darwin was right and Lamarck was wrong when it came to explaining evolution, using giraffes to explain your reasoning.
- Flying fish use large pectoral fins to glide in air. Explain how Lamarck and Darwin might account for the origin of the large pectoral fins and the ability to glide.Bipedalism has many selective advantages. However, there is one disadvantage to walking on two feet: giving birth to an offspring with a large head through a small pelvic opening, which is necessitated by an upright posture, is very difficult. This situation results in a high percentage of deaths (for mother and child) during birth compared to primates. How do you explain the selection of a trait that is both positive and negative?Using analogy / comparative method, describe what the first hominin who moved out of the trees and onto the ground likely looked like. Be sure to describe how you came to that conclusion.
