The 70% genetic similarity of the human and chimpanzee genome according to Tomkins is a difficult number to understand because it has no context. I asked, what if we were to compare other genomes, how much difference would we see using the same criteria for estimating similarity? Because Tomkins is looking at so many types of changes to the genome it is hard to assess those values. I have chosen to look at at much simpler system. The mtDNA genome is almost the same size in animals, has the same genes, almost always in the same order and with almost no gaps or insertions. This means that we can take the DNA strand from one organism and just line it up with another organism and ask – how many differences are their in the actual As,Ts,C,s and Gs of the DNA code?
With this simple system we can then ask, how different are the mtDNA genomes of some representative species of mammals. How did I do it? It is very simple and you can do it yourself.

Human/Chimpanzee - 91.2%
Borneo Orangutan/Sumatran Orangutan - 94%
Lion/Tiger - 92%
Red Fox Wolf - 86%
There are more if you follow the link, but the story is the same. Until Tomkins runs the same tests on these sorts of subjects, they mean nothing.
