Which of the following is not used as evidence to support the theory of evolution? * A. The similarities in embryos of reptiles, birds and mammals.
B. The similarity in bone structure in the appendages of whales, bats and humans
C. Fossils that show ferns and dinosaurs lived at the same time
D. Similarities in DNA between chimpanzees and gorillas

I think A but Im not sure.

Explanation:

An embryo is the early stage of development of a multicellular organism. So idk why I put this in. XD

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
