Textbook Question
Chapter 22, Problem 5TYU
DNA sequences in manv human genes are very similar lo the sequences of corresponding genes in chimpanzees. The most likely explanation for this result is that
- (A) humans and chimpanzees share a relatively recent common ancestor.
- (B) humans evolved from chimpanzees.
- (C) chimpanzees evolved from humans.
- (D) convergent evolution led to the DNA similarlties.

Homology can be defined as the presence of common structures because of shared ancestry. Homology can involve genes, proteins, or anatomical structures. As a result of “descent with modification,” many homologous structures have adapted different purposes. (a) List three anatomical structures in vertebrates that are homologous but have different functions. (b) Is it likely that homologous proteins from different species have the same or similar functions? Explain. (c) Under what circumstances might one expect proteins of similar function to not share homology? Would you expect such proteins to be homologous at the level of DNA sequences?
Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why?
Why are human and chimpanzee DNA 96 percent similar? Please choose the best option.a) Both groups show similarities in their fossil record.b) Humans and chimpanzees share several similar traits such as the use of tools.c) These two species descended from a recent common ancestor.d) Natural selection has favored those particular genes in both humans and chimpanzees.

- 8) Each of the observations provides evidence that supports the idea of common ancestry and evolution. Which one is from the field of molecular biology? A) Mammals have two openings in the skull behind each eye socket, whereas reptiles and bird only have one opening. B) DNA analysis shows that the DNA of Neanderthals is more similar to the DNA of non‑African humans than that of Africans. C) Two closely related but distinct species of squirrels inhabit the north and south rims of the Grand Canyon. D) The embryos of both birds and mammals divide in a radial cleavage pattern instead of a spiral cleavage pattern present in insects.arrow_forward(a) Why can there be multiple codons for an amino acid? Why would this have evolved? (b) What is the advantage of Illumina Next Generation Sequencing?arrow_forward. a. If you found a zinc-finger domain (which facilitates DNA binding) in a newly identified gene,what kinds of hypotheses could you make aboutthe gene’s function?b. Suppose that this newly identified gene shares ahigh percentage of similarity throughout its lengthwith a previously characterized gene in the sameorganism. What does this fact suggest about the origin of the two genes? Would you categorize thesegenes as being: (i) homologous, (ii) paralogous, or(iii) orthologous?
