Humans share approximately 50% of their DNA with bananas
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Roughly 50% of human DNA is identical to a banana's DNA. This is because both share common ancestral genes that have been conserved across billions of years of evolution — particularly genes that control basic cellular functions like energy production and cell division. Humans share about 60% with fruit flies, 85% with mice, and 98.7% with chimpanzees. The closer the evolutionary relationship, the more DNA is shared.
Intuitively, a banana and a human seem to have nothing in common. Discovering that half our genetic code overlaps makes DNA feel less like a blueprint for appearance and more like a universal language of life.
