It’s true. Humans share 50% of their DNA with bananas. Apparently Steve Jones, Professor of Genetics at University College, London is credited with stating this information. Kind of freaky when you think about it. DNA (deoxyribonucleic acid) is what makes us all different, but the difference between us and the next species or even a fruit isn’t as... significant asyou would think.
However, according to Penn State University, a human DNA sequence, if it were a half an inch of a twine, would stretch from New York to the the west coast of California. That makes that 50% seem all the more distant when you think of the whole number/complexity that the percent refers to.
