For example, h. erectus and h. sapien. A crossover with some cranial features of h. erectus and some of h.sapien. From the neck down the two species are identical so it would just be the cranial structures we are talking about. But like I said any mammal will do.
I realize because there aren't any it doesn't disprove your beliefs but I am willing to explore I just don't see any signs of smooth linear evolution. One species disappears then another appears. No transitions.
You have the same access to Google that I have.
I'm not going to explain again how the concept of "transition" fossils is a red herring--because the only way to have every transitional form is to have an example of every generation. It's not my problem if you look at a fossil lineage--one that has been nicely set out for you in order, with explanations--and still are unable to see the evolutionary relationships.
