Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which would most likely be biochemical evidence of evolution?
A

B
Chimpanzees and humans have a similar gene for producing, the protein, hemoglobin.
C
Digestion in all organisms follows a very similar pathway.
D
Fish, bird, rabbit, and human embryos all have gill slits and tails.
Explanation: 

Detailed explanation-1: -Humans and chimps share a surprising 98.8 percent of their DNA.

Detailed explanation-2: -Evidence for evolution: Molecular biology Like structural homologies, similarities between biological molecules can reflect shared evolutionary ancestry. At the most basic level, all living organisms share: The same genetic material (DNA) The same, or highly similar, genetic codes.

Detailed explanation-3: -Which observation supports the inference that humans and chimpanzees share a common ancestor? Chimps and humans have nearly identical DNA.

Detailed explanation-4: -We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago. But humans and chimpanzees evolved differently from that same ancestor.
