Re: ROM Feathered Dinosaur Confusion

In other words, the dinosaur origin of birds is now regarded iun the
mainstream news as a "conservative" interpretation.
I'm not sure that the word "conservative" is appropriate in this context,
but it sure beats the term that Czerkas himself applied to the "dinosaur
origin of birds" hypothesis: "politically correct". Yuck.
Things have certainly changed since the 1960's and 70's when Ostrom's
"birds-from-theropods" hypothesis was regarded as "radical". Back then, the
idea that birds evolved directly from thecodonts was in full swing.
Ironically, Czerkas's contention that birds (and other maniraptorans)
originated from an undefined non-dinosaurian ancestor is more reminiscent of
the "birds-from-thecodonts" hypothesis that Ostrom was arguing against!
Reminds me of that not-so-old expression: Those that do not read the
literature are doomed to repeat it.
