11Worked example 12 — why compare genomes?
If a human gene is 98% identical in sequence to the equivalent gene in a chimpanzee but only 60% identical to that of a fruit fly, this suggests a more recent common ancestor with the chimpanzee.
It also lets us study the gene's function in simpler model organisms.
