Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

If modern animal fossils were ever found in a very ancient geologic period, it would have changed the whole evolutionary theories.
Option B.
<h3><u>Explanation:</u></h3>
Evolution as an event, is very slow and gradually progressive movement. It took millions of years for the unicellular bacteria to evolve and finally make the modern day humans. But the process isn't a haphazard and the evolution processes are well understood by humans. A scientist can clarify how the cell systems became complex to eukaryotic cells, the tissues began to develop, and then the organs and the organ system. The systems like circulatory system, nervous system, muscles, everything slowly grew to evolve animals into a superior one. This is the theory in present days and this is supported by Fossils and different other proofs.
But if one day, a fossil is found which is actually the fossil of a modern animal in very ancient time, its not collaborative with the theories. Modern day animals are born as a result of huge evolutions and presence of them in very ancient times is impossible. So this finding can wipe out present day theories of evolution.
