>Can't a simple morphometric test be made?
The following is from a lurker who asked me to post it:
In a 1991 study, WS Sheppard looked at bee populations in Brazil, near the
original site of the introduction of A m scutellata (Sao Paulo state),
looking for then-current data on hybridization with existing European bee
populations. This study
"...
found evidence of prior hybridization
between the 2 groups, based on the
presence of a presumptive European
mtDNA marker, although the population
was *morphometrically indistinguishable*
from African A m scutellata (Moritz and
Meusel, 1991). A large-scale allozyme
study also revealed that populations of this
region express significant levels of European-
derived introgression, although morphometrically
they are quite "African" (Lobo et
al, 1989)."
