Very familiar with his work. Tomkins seems like a nice guy, but his study is deeply flawed. The data is freely available and I reproduced his work for fun. I found he made some large errors, by excluding some basic controls. Including the controls, we find the human/chimp reads similarity is about 98%. For comparison, the similarity of mice/rats is about 80%.
MIce and rats are the same “kind.” Seems that humans and chimps are too. =)
I could show you his error if you are interested.
