I wanted to really quickly give kudos to Afarensis, who
dutifully ripped apart a dumb question that a creationist asked
in regards to recent research on bipedalism. If you come from
the camp that thinks there isn’t such a thing a stupid question…
then I’m sorry to rain on your parade. There is such a thing as

in its purest form. Here’s question,  “If upright walking is so
