Question

read the passage below and answer the question(s) that follow. scales and feathers. answer the following question(s) relating to the passage titled \scales and feathers\. which claim is best supported by the information about scales and feathers? a. placodes evolved directly from mutations that result in the growth of scales. b. all vertebrates evolved directly from a common ancestor that had feathers. c. changes in placodes over time allowed for the development of different structures. d. the presence or absence of placodes determines whether an organism develops feathers or scales. which evidence best supports the claim that birds evolved from dinosaurs?

Explanation:

The passage discusses the evolution of feathers and scales in birds. Evidence for the evolution of birds from dinosaurs can be supported by changes in placodes over time as placodes are related to the development of feathers and scales. Placodes are structures that play a role in the development of these epidermal features. Option C mentions changes in placodes over time allowing for the development of different structures, which is relevant to the evolutionary link between dinosaurs and birds.

Answer:

C. Changes in placodes over time allowed for the development of different structures.
