The study of comparative genomics has given researchers the ability to look at multiple genomes from different species, which has lead to new ideas about the evolutionary history of organisms. The conclusion is that
A) modern vertebrate species all evolved from very different ancestral species, so there is little similarity between their genomes.
B) modern vertebrate species all evolved from the same ancestral species, but they have changes so that their genomes are very different in modern times.
C) ancestral species contained very similar genomes, but modern vertebrate species have significant
Differences in their genomes.
D) modern vertebrate species evolved from the same ancestors, and a large portion of their genome is conserved.
E) neither the ancestral species nor the modern one resemble each other genetically.

Question

Quizplus · Accepted Answer

Research in comparative genomics has found that the genome of humans and chimps has 98% similarity, which was not a surprise, but they have also found that humans and mice share 85% of their genome. It was surprising that two organisms with such different phenotypes share so much of their genetic material.
