- He studied the microbial ribosomal RNAs (rRNA)
- Hmm... Let's look at some of these rRNAs.
- When he studied the microbial ribosomal RNAs (rRNA) it was found that many of them had distinctly different sequences from the normal bacteria rRNAs.
- Oh look! I notice something, it seems like a lot of them have different sequences from the normal bacteria rRNAs.
- Carl discovers archaebacteria or now called archaea
- These look interesting. How about giving it a name. Hmmm... Oh! Archaebacteria would sound good!
- He concluded that there are three divisions of living systems.
- This means that there is a third life domain, or there are three divisions of living systems.
- Carl says what the living systems are separated into.
- These living systems are separated into: Bacteria, Archaea and Eukaryotes.
- He describes what the different divisions of living systems are as a sign of declaring that there are now three divisions of living systems because of his discovery.
- Bacterias are unicellular organisms. Archaeas are a group of micro-organisms that are similar to, but evolutionary distinct from bacteria. Eukaryotes are organisms whose cells have nucleus enclosed with a nuclear envelope.
