Why did the metatarsals of birds fuse together?
Why did the metatarsals of birds fuse together? Some time ago, some one (I'm
sorry, I don't remember the name) posted onto this list that the fusion was an
adaptation to hopping from branch to branch. I think I didn't get the logit.
Would it be that the fusion made the tarso-metatarsus part of the limb
stronger, and so less vulnerable to facture during rapid deceleration occuring
when the bird "lands" on a branch.
If you have looked into this matter, I'd like to hear from you.
Thanks in advance,
