The following text is a comment that Arnaldo Franco, an AP Bio student, wrote about the post titled Science Club Post: Geocentrism vs Heliocentrism:
This is one of the few posts–if not the first–that contains no writing at all, and yet with only a GIF we are able to find a relation between two scientific discoveries and their processes: the correction of the solar system model and the discovery of DNA as the genetic material. For starters, Ptolemy’s model stated that the center of the universe was the Earth itself; we now know that this was an erroneous thought, just like thinking that proteins were the most important molecules of genetic inheritance due to the uncertainty of DNA. Actually, both reasons for these thoughts are similar: there was not enough evidence and no way to think that the Earth was not the center of the universe and that proteins were not the genetic material. It made sense to many because the sun and planets seemed to revolve around the Earth while proteins were present in almost every biological aspect.
However, there are always great minds that think alike. Both Copernicus and the Hershey-Chase duo knew that there was something wrong: there was a center to both ideas, but the centers that were accepted at the time just did not click. And so, as any scientist would do, these people tested their hypotheses with experiments–Copernicus with astronomical observation and the Hershey-Chase duo with laboratory procedures.
In the end, all of their experiments came to prove them right. For Copernicus’ case, the model of the solar system evolved from this—
As for the Hershey-Chase duo, their famous bacteria-phage experiment
came to show that the central figure of genetic material was indeed DNA. This way, many conflicts involving these two situations were solved, and the road to new scientific discoveries was paved.
P.S.: Do these look similar? If so, how?
