Answer:
Scientific ideas are always welcome as a matter of thinking about something, for example, Darwin and Lamarck
Step-by-step explanation:
Lamarck proposed an idea of how species could evolve, it was a good idea actually if we think nowadays in epigenetics, but it lacked evidences. For a scientific theory to be considered good enough, it needs to have good evidences of that happening, and Lamarck's ideas were poor on that matter. Besides that, Darwin proposed a different idea at the time, with very good background behind it, and a book too. At the time, it took a little bit of time for the scientists to check Darwin's theory, but the accumulated evidence was taken into consideration by the scientists, and through that, Lamarck's ideas were not considered good enough to explain evolution anymore.
