I wonder what would happen if...

We share about half our DNA with bananas and cabbages. That sounds like a lot of shared DNA, yet we look nothing like bananas or cabbages. If a 50% is that significant to produce such a difference between humans and fruits/vegetables, then think about how big a difference a 2% is still going to make.

Yes, this is true, but this is why I asked the tour guide lady about the small changes in regions of the DNA that have a customary or regular function in the appearance of the organism. That's why I also asked her if it could be a different developmental trajectory between chimps and humans. I mentioned that in an earlier post too.
