Humans and bananas don’t share 60% of the same genes; they share many basic DNA sequences common to all life. This highlights common ancestry, not similarity. Like using the same Lego bricks to build very different things, shared genetic components can produce radically different organisms. All life on Earth evolved from the same ancestor so as we branched, our genes branched. We share 60% with bananas, 90% with cats, 98% with gorillas, and 98.8% with chimpanzees.
