i've been reading some interesting information on birds, the dinosaurs that they are.
they're feet show the reptilian history in evolution as you have probably seen the scales, talons and webbed elovutional developments., but i had no idea that they're feathers (the thing that actually qualifies a bird as a bird is its feathers), the feathers are derived from scales as well. the way the feathers are confiquired similar to tree to catch, in this case air.
but the first actual flight! the first time something actually flew. some believe flight evolved as a result of enough ground speed. like the ostrich run. others believe it was the develpoment of a glider, like the flying squirrel coming down from the trees.
has any of you on the forums here ever really thought about the first flight? and if so, which do you think it was. ground speed OR free fall? and why?
