I’m not sure that the oft-cited statistic that humans share 99% of DNA with chimps is as meaningful as it’s made out to be.
Or really worth anything.
We share 50% of our DNA with a banana, also.
My thoughts on this are pretty inchoate, but if you examine the binary sequences of computer code you could express the same similarity about, say, Microsoft Office and Adobe Photoshop.
There’s just more to it than that. A single-nucleotide polymorphism might lead to major changes (or none). It’s just more complex than the “99% chimp” talk makes it out to be.
And if we ever manage to create someone like Ava from Ex Machina, he or she will be 100% human despite having no DNA at all.
We use the wrong tools to measure things all the time. Hammer, nail and all that. Just another example I think.
