Well, duh. An evolutionary biologist will want to separate inherited
from learned behavior, selection from enculturation. There are a lot of
interesting avenues of research on the issue of interpreting human
pointing that *don't* involve hand-waving. IMO, citing the length of
time a species has been domesticated, absent any real evidence one way
or the other about the behavior at issue, is hand-waving.
