Answer:
The invention of the microscope
Explanation:
<em>The invention of the microscope and the ability to see organisms that are otherwise invisible to the ordinary eye led to the establishment of Monera and Protista kingdoms</em>.
<u>Organisms in the Monera and Protista kingdom are microscopic and the invention of the microscope created and avenue for them to be studied extensively by scientists.</u>
Through their studies, taxonomists discovered that these microscopic organisms have characteristics that are neither of plants nor of animals.
<em>Some organisms were found to lack nucleus and membrane-bound organelles which is unlike plants and animals. Some were also found to posses most of the characteristics of animals except that they are unicellular.</em>
These led to the establishment of the Monera and Protista kingdoms respectively.
It is a theory because it is a statement of fact that does not include an explanation.
<span>The RNA world is the hypothesized format of chemical life that existed prior to our current DNA and RNA world. In the RNA world, RNA molecules formed in the primordial soup and began to evolve by self-replication and mutation. This led to increased complexity, natural selection of "better" RNA and diversification of RNA based life.</span>
