Query: No argument with the thesis but:

I have no argument with Dillehay's thesis but for the non-specialist the mind-numbing recitation of obscure dates (Before Present) and obscure locations is not enlightening.I suspect that his research that refutes the Clovis theory is correct and that those academics who are not threatened by this refutation will find it useful but for the non-specialist I suggest that "The Zuni Enigma" by Nancy Yaw Davis which speculates on some of the same theories for the possible "Settlement of the Americas" is much more readable and accessible.Also a minimally competent editor would have been helpful. On page 228 is the following statement: "Although calculations are interesting, however, they are not evidence."
