As a microbiology graduate student at the University of Illinois (Woese's
home turf), I'm curious as how the detractors of the Three Kingdoms
explain evidence such as the presence of TATA-binding proteins in the Archea
that appear to be part of a eukaryotic-style TF IID complex (Marsh, et al.,
1994). If the Archea are not more closely related to eukaryotes than bacteria,
what do you suppose occurred? Horizontal gene transfer?
