They have sequenced a bunch of genomes (216 genomes) of the bee family
and have attempted to determine how bees diversified and spread around
the world. It turns out that they evolved when Gondwana was a super
continent around 120 million years ago. The current dispersal of
genomes and their estimated divergence patterns indicate that bees first evolved in the part of the continent that is now South America and
Africa, and spread around the continent before the major break up of the
land mass 65 million years ago.

The origin and spread of bees parallels the proposed histories of the
evolution and spread of angiosperms associated with various pollination strategies.

So their evolution and spread across the globe is consistent with plant evolution and dispersal, the structure of the supercontinent and
continential drift.

So, the symbiotic equivalent of the predator-prey "arms
race", where each side changes as a result of changes in the
other? Again, interesting. And thanks.

If a big chunk of a super continent retains the name of that
super continent, than there never was a Gondwana in the
first place. It was Pangea.

Science is consistent. If something isn't consistent then it's
not science.
