We are constructing a new observation facility for an autism/toddler research study. Recommendations regarding selection of dual remote digital video cameras, set-up for good sound recording, monitors and vcrs would be welcome.

In this month's issue of _Discover_, there's an item about some research by geneticists Alec Knight and Joanna Mountain, originally reported in March in _Current Biology_, on the presence of clicks in 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, which Knight & Mountain estimate must have flourished over 40,000 years ago. Now, as a historical linguist, I can think of a half-dozen hypotheses to explain why two widely-separated ethnic groups might both speak click languages without positing genetic inheritance (involving such concepts as chains of language/cultural contact, etc.). Is there a serious hypothesis hiding in this biological research which, being neither an Africanist or a phonetician, I've missed out on? Or would it be worthwhile to upbraid the editorial board of _Discover_ for lending credibility to a wrong-headed approach to glossogenetics? Steven Schaufele Steven Schaufele (Ph.D.) Assoc.
