What are the genetic changes that
allow the repurposing of existing body
parts during evolution? For example,
how did bat wings evolve from arms?
Step by step
Solved in 2 steps
- What role do mutations play in the fragment presented above? How is the mechanism of natural selection represented in this situation? How does the reduction in body armor represent an adaptation?At what stages in the development of a human has the evolutionary process introduced genetic diversity?What are the genetic changes that allow the repurposing of existing body parts during evolution?
- how did humans evolve ? where did the earliest form of humans evolve from?. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals."Neanderthals have revealed interesting elements of the human genome". What are those elements ?
- If humans evolved from apes, why are there still apes?What can skeletal anatomy and DNA sequences in existing primates tell us about the study of human evolution?How might you use biotechnology to show humans today have Neanderthal genes, and therefore, Cro-Magnons and Neanderthals interbred with one another?
