So even if humans and bananas share 50% of their genes that does not really say anything about the actual relatedness of the two species
If I ask you to imagine thirteen bananas, not the numeral 13 but 13 distinct, clearly separated bananas, you’re going to run into trouble; it’s easy to imagine four different bananas, all with different shapes and slightly different colors and spots in different places, but thirteen? If I ask you to add twelve to the pile, you may remember that 13+12 = 25, but can you picture it? Can you picture a pile of thirteen distinct bananas, to which you add another twelve distinct bananas, the way you can easily picture in your mind’s eye a pile of three distinct bananas to which you add one?
