I suspect stigma may play a part.. [John Lilly] studied other large-brained mammals and in the late 1950s he established a centre devoted to fostering human-dolphin communication: the Communication Research Institute on St. Thomas in the Virgin Islands. In the early 1960s, Lilly and co-workers published several papers reporting that dolphins could mimic human speech patterns.[7][8] Subsequent investigations of dolphin cognition have generally, however, found it difficult to replicate his results. -- http://en.wikipedia.org/wiki/John_C._Lilly http://en.wikipedia.org/wiki/John_C._Lilly Interesting guy but with a tendency to... go off at the deep end.
