Jaws appear to have evolved from skeletal rods that supported gill slits near the mouth.
Yes
The first class of animals to have jaws were the gnathostomes, which include all jawed vertebrates such as fish, amphibians, reptiles, birds, and mammals. Jaws evolved from skeletal rods that supported the gills in the early jawless vertebrates.
It is believed humans evolved from primates.
"Jaws are believed to have evolved from the first pair of gill arches of agnathans. The second pair of gill arches became support structures for the jaws." - Biology Laboratory Manual, Ninth Edition Darrel S. Vodopich and Randy MooreSo, sharks have fewer gill slits because the first two pairs became the jaw and the structural support for the jaw.
A wolf typically has stronger jaws than a pit bull dog. Wolves have evolved powerful jaws designed for hunting and taking down large prey in the wild, while pit bulls were selectively bred for different qualities such as gameness and strength but do not match the jaw strength of a wolf.
Jaws evolved from the gill bars on fish.
Yes

He believed we evolved and that we were not created by a greater being
The evolution of jaws is believed to be used originally for respiratory purposes. However, it is important to the history of vertebrates mainly because it allowed for more efficient eating.
because it has water and it evolved quicker than earht.
