one talented scientist develops the solution alone.

scientists with similar backgrounds, but different areas of expertise, contribute to the solution.

scientists with different backgrounds and areas of expertise each contribute to the solution.

one scientist proposes an idea and other scientists repeat his or her experiments so that they can accept the idea.
