Humans are 99.9% identical. and what makes us unique is a measly 0.1% of our genome. Human genome is made up of three billion base pairs. The 0.1% that make us unique. They are genes for height or inherited diseases like diabetes.
We each carry three billion base pairs of information inside us with the potential to unravel a piece of the mystery that makes us all so fundamentally human. At the end of the day, we are all still more similar than we are different, but we are just beginning to understand how important our differences are.
