Question

Humans and chimpanzees share a chromosomal inversion that is not present in gorillas. Explain why this suggests that the evolutionary phenomenon known as reinforcement might have played a role in the divergence of the gorilla lineage from the lineage that led to humans and chimps.

Answer 1

A lot of people will say it is the good genetic similarity between chimpanzees and humans. Proponents of evolutionary paradigm state that the framework of human chromosome two provides axiomatic proof that people evolved as a result associated with a shared ancestor with chimpanzees and bonobos. Every single species has a singular amount of chromosomes differing in size and shape. For example, humans have forty 6 chromosomes, various other apes & chimpanzees have forty 8. When exposed to certain dyes, chromosomes will stain in exclusive techniques yielding a pattern of rings on the measurements of theirs. The rings differ in number, spot, thickness and intensity. And also the distinct banding profile of each and every chromosome is able to help geneticists identify them under a microscope. Within the start 1980s, evolutionary biologists when in contrast the chromosomes of humans, chimpanzees, gorillas, and orangutans.These experiments revealed an extraordinary amount of similarity between chimp and human chromosomes. When aimed, the man and corresponding chimpanzee chromosomes screen near identical banding patterns, band places, band size, as well as band discoloration intensity. To evolutionary biologists, this particular resemblance reveals effective proof for human and ancestry was shared by chimpanzee. Thus, probably the closest relative of modern day male is actually regarded as to be chimpanzee.
