Question

2. Chimpanzees and gorillas more closely resemble each other anatomically than either resembles humans. For example, the hands of chimpanzees and gorillas are structurally similar and quite different from human hands. Genetic-distance data suggest, however, that humans and chimpanzees are more closely related to each other than either is to gorillas. Assuming that the genetic-distance data are correct, give two explanations for the observed anatomical similarity between chimpanzees and gorillas.

Answer 1

Answer:

Biologists categorize humans, together with solely a number of alternative species, as nice apes (species within the family Hominidae). The family Hominidae embrace 2 distinct species of Pan troglodytes (the Pan paniscus, pygmy chimpanzee, and therefore the common Pan troglodytes, Pan troglodytes), 2 species of ponged (the western gorilla, great ape, and therefore the eastern gorilla, ponged graueri), and 2 species of orang (the Malaysian orangutan, orangutang, and therefore the Sumatran orangutan, Pongo abelii).

Both chimpanzees and gorillas had little C4 genes. The human factor was long thanks to Associate in Nursing ERV. Apparently, orangutans and inexperienced monkeys had constant ERV inserted at precisely the same purpose. This is often particularly vital as a result of humans are imagined to have a more modern common root with each chimpanzees and gorillas and solely a lot of distantly with orangutans. However constant ERV in mere the same location would imply that individuals and chimps had the more modern common root. Here may be a sensible case wherever ERVs don't line up with the expected biological process progression. Notwithstanding, they're still delayed as proof for common ancestry.

Significantly, not all of the information support chimp-human mutual ancestry as nicely as evolutionists generally recommend. Above all, once scientists created a careful contrast among human, chimpanzee, and ponged genomes, they found a major variety of genetic indicators wherever humans harmonized gorillas a lot of carefully than chimpanzees! So, at 18

Answer 2

Answer:

Human evolution in the hominid family occurred faster than between Chimpanzees and gorillas. Neutral mutations may result in sequence divergence between organisms that are structurally similar (in this case, chimpanzees and gorillas)

Explanation:

Human and chimpanzee share higher sequence identity than predicted in the hominid family since observed mutations are necessarily associated with functional divergence
