Will the producers of this video please list the cellular evolutionary steps it took to evolve this beak? It's one thing to throw the term evolution around without evidence. Quite another to back up your claims with scientific evidence. I like to call this evolution of the gaps.
Evolution! And they are looking amazingly beautiful 😍
What a miracle!
It evolved....what nonsense....god made it that way
Wow that's amazing. Who would have known This??
yeah, evolution. I wonder how man died of heat exhaustion before evolution got it right.
Thermo-regulation seems like a very plausible reason for the Toucans' large beak. The beak seems very well served with small veins/capillaries. Then again...
Its beak is a big radiator.
Toucans look like tropical puffins
I've never seen a flying toucan before but now I have.
Cuz- female toucans are crazy.
thats pretty amazing
It amazes me that some insist that a feature - like a bird's beak - has to have only one function. It doesn't have to be just for attracting a mate, or to just intimidate other creatures. Or even only to cool the bird. Why not all of the above? A mate may prefer a big beak BECAUSE a big beak helps the species as a whole, or BECAUSE it keeps danger away from the female and her brood. Or because it cools the bird. Or any of a number of reasons. It's not always just one or the other.
