First, I want to introduce myself. My name is Bernardino P. Perez-Moreno,
and I am one of the authors of the paper on the new Early Cretaceous bird
Second I want to make some comments about the message you sent to the
list some days ago. The authors of this paper are never ignoring "good sense
and good science". You should read the paper before you ever think this kind
of thinks. The paragraphs on which your message was based on were written by
the science editor of a newspaper, not by the authors of the paper. In the
paper, we never said anything about ground, trees nor cliffs. We just said
that _Archaeopteryx_ probably had some kind of constraints for taking off
and landing because it has no alula (no matter from where it try to take off
or land). We never try to use _Eoalulavis_ as an evidence for any theory of
the origin of the avian flight, just as an evidence of the early phases of
the evolution of the avian flight.
I hope the next time you will make the thinks in the right way, and you
read the original paper before you make bad science fiction as this time,
because you don't obtain all the data you have available to make science
(something that other people, like me and my colleages, are trying to do
every day of their lifes).
