All,

I am certainly looking forward to reading the paper and, needless to say, a response. As a matter of fact, it would be very nice if the Forum were to be presented with a preview of what the latter might be.

Keywords:
African replacement hypothesis, Out of Africa, Neanderthal, Australasia

Abstract:
In this paper we critique two recent studies that have been claimed to disprove the Out of Africa hypothesis for modern human origins (Hawks et al., [2000]; Wolpoff et al., [2001]). We show that the test prediction employed by Hawks et al. ([2000]) and Wolpff et al. (2001) is not relevantto many versions of the Out of Africa hypothesis, and that the key specimens they used are problematic in terms of morphological representativeness. We also show that there are significant problems with the character state datasets employed in the studies. Lastly, we highlight evidence that the main method used in the studies (pairwise difference analysis) is not reliable when applied to the type of data employed by Hawks et al. ([2000]) and Wolpoff et al. ([2001]). In view of the foregoing, we contend that Hawks et al.'s ([2000]) and Wolpoff et al.'s ([2001]) claim to have disproved the Out of Africa hypothesis cannot be sustained.

I've been able to obtain a copy just now, through access. The conclusion is similar to the abstract:

"In the present article we have highlighted what we
consider to be some major shortcomings of two recent
studies that have claimed to have disproved the Out of
Africa hypothesis for modern human origins (Hawks et al.,
2000; Wolpoff et al., 2001). These shortcomings can be
summarized as follows. One, the prediction on which the
studies focussed is not relevant to many versions of the
Out of Africa hypothesis. Two, the key specimens employed
in the studies are problematic in terms of morphological
representativeness. Three, many relevant characters
are ignored, and many of those that are examined are
of questionable phylogenetic utility. Four, little confidence
can be placed in the character state assignments used in
the studies. Five, the main method used in the studies is
inappropriate because, when applied to comparable data
sets, it yields phylogenetic relationships that are most
likely incorrect. In view of the foregoing, we aver that
Hawks et al.’s (2000) and Wolpoff et al.’s (2001) claim to
have disproved the Out of Africa hypothesis cannot be
sustained."

Essentially this paper is a limited response to claims made in two specific papers. It adds to the merry-go-round which is OOA vs Multiregionalism.

The abstract reminds me of a paper (I don't remember the authors, but I think it was posted by you , Mikey) about the methodological approach of the two schools OoA and MRE : vice versa neglecting the data and refuting the methods of the other school.
One should read Bräuer et al.'s article to find out if it falls into this category.

Arne, the article you are thinking of is:
