Uncommon Knowledge: Is your DNA unique?
It’s considered common knowledge now that no two people are exactly alike, and that those differences are coded right into our DNA. You may be surprised to learn, however, that all of those differences between us only appear in only 1% of our DNA. That means that in 99% of our genetic makeup, the entire human race is exactly alike. If it seems impossible that just 1% could account for the variety found among earth’s population: 97% of our DNA is exactly the same as that of an orangutan!
