- Just as anatomical homology can lead to vestigial structuressuch as human wisdom teeth and the wings of flightlessbirds, genetic homology can lead to vestigial DNA sequences.For example, most mammal species produce an enzyme,L-gulonolactone oxidase, that catalyzes the last step in the productionof vitamin C. The species that produce the enzyme areable to do so because they all inherited the gene that encodesit from a common ancestor. Humans, however, do not produceL-gulonolactone oxidase, so we can’t produce vitamin C ourselvesand must consume it in our diets. But even though wedon’t produce the enzyme, our cells do contain a stretch of DNAwith a sequence very similar to that of the enzyme-producinggene present in rats and most other mammals. The human version,though, does not encode the enzyme (or any protein). Weinherited this stretch of DNA from an ancestor that we share withother mammal species, but in us, the sequence has undergonea change that rendered it nonfunctional. (The…A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis? Amino acid analysis of the cytochrome shows significant differences in the sequence of amino acids between humans and goriffas. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla's DNA sequence. The cells of the eye in embryos of gorillas and humans follow a similar pattern of development chimpanzee embryos are different Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.
- Rates of evolution appear to vary in different lin-eages. For example, the rate of evolution in the rat lineageis significantly higher than in the human lineage. Theserate differences are apparent whether one looks at changesin nucleotide sequences that encode proteins and are sub-ject to selective pressure or at changes in noncoding nucle-otide sequences, which are not under obvious selectionpressure. Can you offer one or more possible explanationsfor the slower rate of evolutionary change in the humanlineage versus the rat lineage?Atlantic Thorny oyster.

- True segmentation (metamerism)? evolved 3 separate times (True/False)?Neanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate. Why did Neanderthalsbecome extinct? State at least two major factors toexplain their fate.Please answer only A, B, C. I will repost this question for the rest. Include a brief explanation for each answer.
