What’s wrong with the guy, doesn’t he know that all
science has been as exhaustively studied as he did for the
obvious protofeathers. How dare he suggest that they
are not feathers at all. Are we gonna have to find
another “for sure” candidate? It’s getting tiring, to
keep on postulating putative candidates only to find out
they don’t really pass muster. How long has this been
going on? 125 years?
Science is never done, and the theories are never all the way right. They do tend to get better over time, but not always. Sometimes, researches invest so much of themselves in a theory its hard to let it go.
