Spontaneous generation, the claim that living things can come from nonliving things, was an integral part of the theory of how life began and evolved for many years. In the 1600s, Francesco Redi was the first scientist to try to disprove spontaneous generation. Louis Pasteur, in 1859, finally disproved this claim with scientific evidence.
Based on these events, which is the best statement that can be made about scientific theories?
Scientific theories are tested in the same lab every time.
Scientific theories can never be disproven once they are accepted by scientists.
Scientific theories are well-tested hypotheses supported by an abundance of hypothetical claims.
Scientific theories are the culmination of many scientific investigations drawing together all current evidence.
