According to the theory advanced by ornithologists, which of the following is most likely to have been a modern-day descendant of the archaeopteryx? A. the lizard B. the alligator C. the crow D. the mosquito

Short Answer

Expert verified
According to ornithologists, the modern-day descendant of the archaeopteryx is most likely the crow (option C) as it belongs to the bird group, which is considered a direct descendant of theropod dinosaurs like archaeopteryx.

Step by step solution

01

Understanding Archaeopteryx

To identify which option is the correct descendant of archaeopteryx, we need to understand what archaeopteryx was. The archaeopteryx is a genus of bird-like dinosaurs that is transitional between non-avian feathered dinosaurs and modern birds. They had features in common with both modern birds and reptilian dinosaurs.
02

Ornithological Theory

Ornithology is a branch of zoology that concerns the study of birds. According to ornithologists, birds are direct descendants of theropod dinosaurs, like the archaeopteryx. Therefore, it's crucial to understand the link between archaeopteryx and modern birds to find the most likely answer.
03

Comparing Characteristics

Let's compare the options given to the archaeopteryx: A. Lizard: reptile, not a direct descendant of dinosaurs like archaeopteryx. B. Alligator: although a reptile related to dinosaurs, they did not evolve directly from the archaeopteryx lineage. C. Crow: a bird, which is considered a direct descendant of theropod dinosaurs like archaeopteryx. D. Mosquito: an insect, not related to archaeopteryx or dinosaurs.
04

Identifying the answer

Based on the characteristics and the ornithologists' theory, we can conclude that the modern-day descendant of the archaeopteryx is most likely the crow (option C) as it belongs to the bird group which is considered a direct descendant of theropod dinosaurs like archaeopteryx.
