6. Which organism is closely related to humans? 7. Which organism is least related to humans? 8. If the amino acid sequence of the two organisms are similar, would their DNA be als similar? Why? 9. Compare Chimpanzee and Gorilla relatedness to human 10. Do you think the chimpanzee, Gorilla and humans have a common ancestry? Explain your answer. D. Direction: Distinguish analogous structure from homologous structure by completing the table. Choose your answer from the heading
Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.
2. Sponges
Sponges or comb jellies are the sister group to all other animals, so they are the least related.
3. Yes. If the amino acid sequence of two organisms are similar, then the organisms' DNA sequences would also be similar. The central dogma of biology states that DNA contains the key for RNA, which then codes for proteins. ... These codons will be important in the second phase of protein synthesis called translation.
4. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 98.8 percent of their DNA.
5. According to the new genetic research—when combined with known fossils—the lineage that led to humans, chimps, and gorillas evolved from a common ancestor about 10 million years ago. Humans and chimps then popped off of that lineage some 6 million years ago, according to the new study.
