Yes
ornithischian
Theropod dinosaurs for one.
Ornithischians with a hip structure similar to that of present day birds.
vestigial organs such as a tail bone in humans and a hip bone in whales. also, the skeletal structure of wings of birds, flippers of whales, and hands of humans are all very very similar in structure.
because some dinosaurs like the velociraptor have been discovered with feathers. and even some dinosaurs in there bone structure have the shape of birds. like the t-rex has the hip structure of a lizard and the velociraptor had the hip structure of a modern day bird
Dinosaurs were divided into two big groups: ornistichia (bird hip) and saurischia (lizard hip). The confussing part is that scientists believe that birds evolved from a group of therapods similar to small velociraptors and therapods are saurischia.
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
Both birds and mammals belong to the amniotes group, which evolved from a common ancestor that lived around 310 million years ago. Molecular studies, anatomical similarities in the skeleton structure, and shared features in early embryonic development provide evidence supporting the evolutionary link between birds and mammals. Additionally, the discovery of transitional fossils like Archaeopteryx, which exhibits characteristics of both birds and dinosaurs, further supports the evolutionary relationship between birds and mammals.
Dinosaurs are divided into two main groups based on their hip structure: Saurischians and Ornithiscians. Saurischia means "lizard hipped" and Ornithischia means "bird hipped". Saurischian hips had the pubis pointing forward and the ischium pointing backward. All the carnivorous dinosaurs (the theropods) and sauropods were saurischians. Ornithischian hips had the pubis pointing backward and parallel to the ischium. They include all the other dinosaur groups such as the ceratopsians and the ornithopods. Ironically, birds do not descend from this type of dinosaur. Instead, they are descended from the theropods, who were saurischians.
