How similar is human DNA to other species?
Humans share about 98.7% of their DNA with chimpanzees, ~85% with mice, ~60% with fruit flies, and even ~50% with bananas. The human genome contains about 3 billion base pairs, but only ~1.5% codes for proteins. The 1.3% difference from chimps accounts for all that separates us.
