You've probably heard about how humans share over 98% of their genes with some chimps. It shows just how small differences in DNA can make a huge difference in the way life takes shape. Well, how about this one? We share 50% of our genetic make up with a banana.

Scientists have found this thanks to the Human Genome project, which mapped all the genes in the human body and allowed them to compare our genes with other life forms. Here are some other interesting comparisons: We share 60% of genes with a Fruit Fly, 75% with a mouse and 80% with a cow!

It's interesting to think how little different all living things are. Scientists say that this is because plant and animal life separated about 1.5 billion years ago, and the genes we share are due to our common ancestors.
