The images show fossils of a modern bird and two extinct organisms( a Tyrannosaurus rex and archaeopteryx). Based on the structure of the three organisms, it can be concluded that blank . The archaeopteryx and have wings, while dinosaurs have limbs. So, it can be concluded that blank.

Many individuals consider that Archaeopteryx would have been the first bird, however, many paleontologists are against it. The findings of many fossils of Archaeopteryx have revealed that though the creature exhibited wings, the majority of its characteristics were of reptile, like the existence of full teeth set. Apart from this, the wings formation of the creature demonstrated that it was not completely capable of flying.  

No matter what, the presence of wings makes them closely associated with the modern time birds. Thus, it can be concluded that Archaeopteryx could be considered as an intermediate between the reptiles and the birds and is a precursor to the modern-day birds' evolution.  

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
