A transitional fossil is one that shows a state intermediate between
two other groups, and that thus tells us about the nature of the
transition. That's all. Archaeopteryx is an excellent transitional
form, which is why it gets mentioned so often.

IN other words I'll examine, reason, and not accept dogma.

That's an excellent idea. But I have not observed any signs in you of
either of the first two.- Hide quoted text -

The latest fossils clearly illustrate it was a fully capable flying
bird and that's all there is to it.

um - last I looked birds didn't have jaws full of teeth, nor yet long
bony tails..  and I believe Archaeopteryx is missing a few features that
birds have nowadays - e.g. a keeled sternum.  I agree that Archaeopteryx
had feathers, and probably flew, but it sure wasn't a modern bird.  In
fact, it was sort of transitional...  But of course, I defer to your
expertise in paleontology - that was one of your degrees, right?  - Hide quoted text -

It is true that Archaeopteryx had claws on its wings and teeth in its
mouth, but these traits do not imply that the creature bore any kind
of relationship to reptiles. Besides, two bird species living today,
the touraco and the hoatzin, have claws which allow them to hold onto
branches. These creatures are fully birds, with no reptilian
characteristics. That is why it is completely groundless to assert
that Archaeopteryx is a transitional form just because of the claws on
its wings.

"We were fully expecting to find a dinosaur like brain," Dr Milner
told BBC News Online. "Instead, it was completely bird-like."

The computer-generated image revealed that the anatomy of the brain
corresponded very closely with that of modern flying birds.

It revealed well-developed semicircular canals in the inner ear, which
are used for balance, and enlarged optic lobes for vision. Both
essential features for efficient flight.

"The brain scan basically showed that the Archaeopteryx had all of the
structures that allow birds to fly," added Dr Milner.

Fairly conclusive

The findings present fairly conclusive evidence that Archaeopteryx was
once airborne, according to the lead researcher.

Dr Milner commented: "This all suggests that the development of the
bird brain goes hand in hand with that of the physical structures,
e.g. the wings, that allow it to fly.

"In fact, the brain is so bird-like, that the flying process must have
evolved much sooner than anyone thought."
