Charles Darwin was formally educated in Theology, and married his first cousin. He also apparently invented irony.
Darwin didn't study African or European swallows; he studied finches, at least so far as the H.M.S. Beagle was concerned. His wife was English as well and, being his first cousin, was clearly open-minded. Thus, the European swallow may have been an inevitable 'hobby study'.
Schneider Weisse is still a delicious winter beer.
It is the weekend.
I am out of Schneider Weisse.
