I was looking at the Nat Geo dino pages when I saw the factoid about
eoalulavis, the 'first skilled flier'. I checked the name and found that it
was the first with an alula, a tuft of feathers on the thumb, which helps
with takeoffs, landings, and slow flight. I thought from prior discussions
that takeoffs and landings had something to do with wing flexibility and
motions. How does a tuft of feathers help with this?
Also, if I read the summary correctly (a page wouldn't open), eoalulavis was
an enantiornithe. Did the alula develop twice?
