Yes, but don’t worry. It’s not as strange as it sounds. While bananas and humans share 60% of their DNA, this simplifies a fascinating truth: all life on Earth is based on DNA and evolved from a common ancestor. So, while we don’t have 60% of the exact same genes, we share many fundamental genetic building blocks.
Can you turn a banana into a human?
No, you can’t. While you can build both a cabin and a boat using Legos: the final structures are vastly different. Similarly, while humans and bananas share about 60% of their genetic material, you cannot convert one into the other.
Can you turn brown eyes blue?
Yes! Right now it’s only theoretical, but within about 10-20 years, we’ll likely be able to safely alter the genes of adults for cosmetic purposes.
This involves targeting specific cells in adults and altering their DNA. As these cells reproduce, they pass on the new genetic programming, resulting in the desired change. In this case, we would target the pigment cells in the iris, specifically the OCA2 and HERC2 genes. Once altered, the brown eyes would turn blue as the old cells are replaced. Since iris cells live longer, this color change would likely take a few years.
