In this month's issue of _Discover_, there's an item about some

> the languages of the Hadzabe people of Tanzania and the Juj'haonsi of
> `southwestern Africa' (Namibia? can't seem to find it in my copy of
> the _Ethnologue_).  It is apparently suggested that the fact that
> these two ethnic groups, otherwise quite unrelated to each other
> (genetically), both have clicks in their languages must mean that the
> clicks are inherited from the language of their last common ancestor,

I would suggest this as a topic for discussion on this list, since
this hypothesis has been widely bruited in the popular press (e.g. in
the New York Times), and seems to me to hinge on the following
ludicrous syllogism:

Two (perhaps geographically proximate) languages share a distinctive
phonological feature.  This feature is typologically unusual.
Therefore, the two languages are genetically related.

As a relevant counter-example, specifically in the case of clicks, we
need look no farther than Khoisan and Xhosa.
