It just goes to show that we make new discoveries and expand our understanding of the world every day! We are in a great position to examine our past and rethink what is actually taking place as we progress in science and technology. More importantly, stories like these remind us that we never have all of the information.
Mistakes are made constantly, and in a few hundred years ideas that we hold now may be looked back on as silly. Discovery is important, but rediscovery can be just as fulfilling!
