Describe and explain one real-life and/or recent example of how scientific knowledge had to change or adapt in the face of new discoveries. OR
Describe and explain one old (i. e. not accepted anymore...) scientific model or theory. Then, explain why or how that old model had to change.

Science is a particular way of knowing about the world. In science, explanations are restricted to those that can be inferred from confirmable data—the results obtained through observations and experiments that can be substantiated by other scientists. Anything that can be observed or measured is amenable to scientific investigation. Explanations that cannot be based on empirical evidence are not a part of science.

Explanation:

Modeling can help scientists study things that they can’t directly observe. Plesiosaurs no longer exist. So, scientists can’t directly see how they moved their flippers. However, they can use existing evidence—the fossil structures of plesiosaurs—to bring these organisms to life in a computer model.
