How much DNA do humans share with bananas?

Why this works

At first glance, the idea that humans share a significant portion of their DNA with bananas seems utterly bizarre, but this riddle cleverly nudges us to rethink our understanding of genetics and evolution. The answer, about 60%, arises from the fact that all living organisms share a common ancestry, and thus, there are fundamental biological processes and structures that are conserved across species. While humans and bananas are vastly different in form and function, the underlying genetic code that governs cellular processes is remarkably similar at a fundamental level, illustrating how evolution shapes life on Earth. This revelation invites us to appreciate the interconnectedness of all living things, reminding us that we are all part of a grand tapestry woven through eons of evolution. The "aha moment" comes from realizing that the very building blocks of life are not solely confined to complex organisms like ourselves but are also shared by simpler forms such as plants. This connection is a testament to the common heritage of life, where even the most disparate species can share a substantial amount of genetic material. As a fun trivia nugget, this concept of shared DNA isn't just limited to bananas; humans share about 98% of their DNA with chimpanzees, our closest living relatives. This illustrates the wonders of genetic similarity across species, making us ponder the intricate web of life that ties us all together, from the mightiest mammal to the humble banana.
