The table contains only thirty vocabulary items, none of them attested in every brach of the family and most attested in less than half, and all with reconstructed proto-forms that look like this: *(ʔa-)bVr - "bull". Honestly, maybe I'm being too harsh, but that seems like something you'd see from an Altaicist.Wikipedia wrote: There are two etymological dictionaries of Afroasiatic, one by Christopher Ehret, and one by Vladimir Orel and Olga Stolbova. The two dictionaries disagree on almost everything.[56] The following table contains the thirty roots or so (out of thousands) that represent a fragile consensus of present research:

The last red flag for me is that the family as we know it today was apparently first codified by Greenberg, whose track-record for the rest of the languages of Africa is bad, to say the least. Of his other two major proposals, Niger-Congo and Nilo-Saharan, the first is known to be dubious in scope, while the latter is generally regarded as more-or-less bullshit. Of course, proposals linking Amazigh with Semitic, and sometimes with Cushitic or Egyptian, do predate Greenberg's involvement, but I can't help but notice his prominent role in the current understanding of the family.
I've also heard mumblings at various points that the inclusion of Cushitic and, especially, Omotic is suspect, with the Amazigh-Egyptian-Semitic grouping being more confident, but I'm not sure what to make of these claims.
Anyway, I suppose my point boils down to this: the Afroasiatic proposal is an extraordinary claim, and I have yet to see extraordinary evidence. That doesn't mean it isn't out there! Again, I am very much a novice. So I'm curious, to anyone here who is more familiar with the AA family, what is the evidence, anyway? What should the non-expert do to convince themselves that the AA family has any more validity than other initially plausible looking macro-proposals like Altaic?
