What is the primary way in which other animals have shaped human evolution? Explain in detail.
Tarsiers are one of the small species of primates generally found in tropical islands like Bohol, Philippines. Gibbons are small apes usually found in the forests of Southeast Asian regions. Chimpanzees are considered to be the highest form of "thinking organisms" on Earth.
The theory of evolution asserts that these species evolved from a related ancestor. By observing the given figure. How will you support or reject the said claim?
If you were to create an evolutionary tree of modern birds, where would you expect to place the roadrunner (judging by its appearance in this figure) as compared to a house sparrow or pigeon?

- A new organism has been discovered! Our fictional creature, “the Snipe”, has structural similarities to a deer, pig, and beaver. It has a pig’s head with antlers, and big buck-teeth, a deer’s body, and a wide, flat tail. Please describe how you could determine its place on the evolutionary tree below.

Which of the apes’ adaptations would be biologically possible, and which ones would be impossible, from your understanding of apes on Earth today?

- While the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?arrow_forwardIf humans evolved from apes, why are there still apes?arrow_forwardThe upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the corresponding bones in whales have very different shapes and proportions. However, genetic data suggest that all three kinds of organisms diverged from a common ancestor at about the same time. Which of the following is the most likely explanation for these data? Group of answer choices Forelimb evolution was adaptive in people and bats, but not in whales. Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy. Humans and bats evolved by natural selection, and whales evolved by Lamarckian mechanisms. Genes mutate faster in whales than in humans or bats.arrow_forward
- Of the following, which one is an example of an evolutionary explanation (as opposed to a functional explanation)?A. People evolved a fear of snakes because many snakes are dangerous.B. Humans have a (tiny) tailbone because our ancient monkey-like ancestors had a tail.C. People evolved an ability to recognize faces because that ability is essential for cooperative social behaviors.D. People evolved a tendency to form long-term male–female bonds because human infants benefit from the help of two parents during their long period of dependence.arrow_forwardCan you explain what convergent and divergent evolution is and explain why it may be hard to distinguish between the two..?arrow_forwardWhich of the following does not represent a shared derived homologous trait, in other words, which IS an example of an analogous trait?
