Ron O really seems to think that hairlike growths are feathers.
Why didn't you call him on this, Alan. Didn't you look at the
linked article?

I doubt that they got anywhere beyond light and dark. The article nowhere
suggests spectral colors. But then, that sort of thing never stopped
Ron O from pontificating.

Maybe, but there is lots going on here to which you are oblivious
because of your lack of interest in paleontology.
True, Ron O himself has only a passing interest in paleontology, being much
more fond of spewing contempt at people, but that's another story.

What you don't seem to realize, Alan, is that those aren't feathers
on Sinosauropteryx. They are hairlike growths that optimists like
Harshman call "protofeathers" because he thinks they evolved into
feathers later on.

Ron O is here showing what an amateur he is, unable to think of any
reason for hair except his UNSPOKEN single reason hair evolved
on synapsids.
Hair has now been traced back to early synapsids that are tens of
millions of years earlier than mammals.

*I* have the fact that pterosaurs also had hairlike growths, but did
not evolve feathers.
And even YOU have the fact that no mammal ever evolved feathers
despite having protofeathers -- excuse me, I mean hair. Even bats
didn't evolve them, but solved the problem of flight a different way.
And so your question was a good one.

If you actually had some interest in paleontology, you might be a lot
more effective against pretentious, self-centered, self-satisfied
jerks like Ron O.
