Science says that our DNA is 85% similar to mice, 61% similar to fruit fly, and even 60% similar to banana, etc., then, we’re so much different in appearance. How does the remaining %, etc. able to make us who we are as different from other species we’re genetically similar to.

Science says that our DNA is 85% similar to mice, 61% similar to fruit fly, and even 60% similar to banana, etc., then, we’re so much different in appearance. How does the remaining %, etc. able to make us who we are as different from other species we’re genetically similar to.

Answer 1

Because the human Genome is made of approximately 3 billion base pairs of DNA, 15 % difference is still very significant. 15 % of 3 billion is still 450 million, so that explains the differences between us and bananas and mice.
When a number is so significant, even 1.5 % ( Here, that would still be 45 million ) is a lot.
