Depends who you ask--I've seen some scientists who say they are & some who say they aren't & some who aren't sure either way.Birds are birds are dinosaurs.
Scientists are like that.
We mostly get to hear the ones with the good press agents.
They may be right or they may be wrong, or somewhere in between--but there are ones we hear more about.
But things like that are rarely ever agreed upon across the board.
And history has shown that sometimes the ones in the majority were wrong.
