What do a banana and a human have in common?

The 50 per cent figure for people and bananas roughly means that half of our genes have counterparts in bananas. For example, both of us have some kind of gene that codes for cell growth, though these aren't necessarily made up of the same DNA sequences. Humans share 50% of our DNA with a banana. Twenty five per cent of all of your bones are in your feet. The average person walks the equivalent of three times around the world in a lifetime. Humans don't just share a high percentage of DNA with bananas - we also share 85 percent DNA with a mouse and 61 percent with a fruit fly. "The remarkable thing is that despite being very far apart in evolutionary time, we can still find a common signature in the genome of a common ancestor.

DNA between a human and a banana is 41 percent similar.
