1. Why was communication through books, letters, and lectures such an important factor in the development of the cell theory? What do you think would happen if scientists today were unable to communicate with each other?

In science, we build on the works of others. If we know the works of others, we can replicate them in varying situations and attempt to answer questions they have raised. We can design experiments that will help us choose between competing explanations. However, this cannot be done, if they are not communicated to us.

Just think of the basic laws of nature that you accept without question. Without exploration and scientific investigation being communicated to others, we would probably be back in the dark ages.

This also applies to cell theory.

I hope this helps. Thanks for asking.
