Question

select the correct answer from each drop - down menu.
the images show fossils of a modern bird and two extinct organisms (a tyrannosaurus rex and an archaeopteryx). based on the structure of the three organisms, it can be concluded that
the archaeopteryx and bird have wings, while dinosaurs have limbs. so, it can be concluded
drop - down options: they share a common ancestor, they do not share a common ancestor, they are not linked through evolution

Explanation:

The shared skeletal structures (wings/limbs) between the modern bird, Tyrannosaurus rex, and Archaeopteryx indicate an evolutionary relationship, meaning they descend from a common ancestor. The other options contradict evolutionary evidence from comparative anatomy.

Answer:

First dropdown: they share a common ancestor
Second dropdown: dinosaurs have limbs. So, it can be concluded that they share a common ancestor
