Archaeopteryx probably cannot tell us much about the early origins of feathers and flight in true protobirds because Archaeopteryx was, in the modern sense, a bird.
Like a red morn that ever yet betokened,
Wreck to the seaman, tempest to the field,
Sorrow to the shepherds, woe unto the birds,
Gusts and foul flaws to herdmen and to herds.
I read the Bible and know little of its history, but the human beings who wrote it were instruments of Divine Power, and Jesus forged a far stronger bond than the ten commandments: love. Birds and monkeys, or any of God's creatures, obey their instincts and merely do what they're programmed to do. In the case of the human being, things are more complicated because we know about love and its traps.
Paleontologists have tried to turn Archaeopteryx into an earth-bound, feathered dinosaur. But it's not. It is a bird, a perching bird. And no amount of 'paleobabble' is going to change that.
Let sinful bachelors their woes deplore; full well they merit all they feel, and more: unaw by precepts, human or divine, like birds and beasts, promiscuously they join.
When you have shot one bird flying you have shot all birds flying. They are all different and they fly in different ways but the sensation is the same and the last one is as good as the first.
