You have to pay attention to time. One cannot glide effortlessly across
millions of years. Sternberg's post speaks to the presence of, please
notice, *Ensete* not *Musa* in the same family but not the same genera in
Oregon 43 MILLION years ago. This says nothing about the presence of Musa
acuminata triploids in the last 10,000 years in South America. Sternberg
(private communication) pointed out that this would require other kinds of
43 million years ago not only were there no humans there were no apes, or
the common ancestor of humans and apes such as *Proconsul*. Thousands, if
not millions, of species of plants and animals have become extinct in this
lenght of time. Remember that there were no horses in the New World when
Columbus arrived even though our most complete record of horse evolution
is found in North America.
Re your comments on domestication. Humans only domesticated plants about
10-11,000 years ago a miniscule time compared to the time *Homo sp.*
wandered about as hunter-gatherers (1-2 million years) much less than 43
