The percentage difference is calculated using a very odd system which ignores all the actual differences.<p>For example if Humans and Bananas each have 5000 coding genes in common the difference will be measured only on those genes we actually share (out of 20-25K coding genes in humans, no clue how many coding genes do bananas have), so the difference is actually much greater than the 50%, 4%, 1% or what ever figure you get because the big differences are simply discarded.<p>These days there&#x27;s a cartoon for everything :)
