This isn't true: https://en.wikipedia.org/wiki/Hoatzin
... Since Archaeopteryx had three functional claws on each wing, some earlier systematists speculated that the hoatzin was descended from it, because nestling hoatzins have two functional claws on each wing. Modern researchers, however, hypothesize that the young hoatzin's claws are of more recent origin... A similar trait is seen in turacos, whose nestlings use claws on their wings to climb in trees.
2010, simply because of how english works.
If you say 2001 as twenty one, it's confusing. Same goes all the way up to "twenty nine".
And it's more garbled and slower to say "twenty oh one" vs "two thousand one", especially if you're speaking quickly.
"Twenty ten" and up, however, starts making sense as a different piece of information and can be used easily.
