Four-legged Snake Fossil Stuns Scientists, Ignites Controversy

sciencehabit writes: Scientists have described what they say is the first known fossil of a four-legged snake. The limbs of the 120-or-so-million-year-old, 20-centimeter-long creature are remarkably well preserved and end with five slender digits that appear to have been functional (abstract). Thought to have come from Brazil, the fossil would be one of the earliest snakes found, suggesting that the group evolved from terrestrial precursors in Gondwana, the southern remnant of the supercontinent Pangaea. But although the creature's overall body plan—and indeed, many of its individual anatomical features—is snakelike, some researchers aren't so sure that it is a part of the snake family tree.

    Heroism takes many forms.

    McCain was the son of a high ranking Admiral, and a potentially valuable political pawn for the North Vietnamese. They offered him all sorts of inducements, nice treatment, etc, if he'd make statements for them. He refused, and they tortured him instead, to the point that he can't even raise his arms above his shoulders today.

    They offered to release him early, ahead of his fellow prisoners, and he refused, insisting that all previous prisoners be released first (according to military rules), even though that meant he'd be enduring more of that hellhole.

    Heroism isn't just about standing up with a machine gun on each arm and shooting up the enemy single-handedly.
