The Three Domains
Fungi, a part of both bacterial and eukaryote domains.
Introduction
The three domains of life. Once, there were two, and now there are three - Bacteria, Eukaryote and the newest one, Archaea. All living organisms are placed into one of the three categories. The oldest is bacteria, which has been around since the dawn of time. The second is Eukaryote, which has been around for about 2 billion years, and the youngest being Archaea, which has been around for longer than discovered, in 1977.
Below is a list of sections that you can view information on in this section.

As this section is so small (currently), I'm going to explain the whole section. Up until as recently as 1977, it was thought there were just two domains of life - bacteria and eukaryote. In 1977, Carl Woese discovered a third in the form of archaebacteria, later renamed as just Archaea. This was proved to be right, as they are other single-celled organisms that interact differently to true bacteria.
So, now we know there are three domains of life, we can continue to find more and more out about them, and it's all thanks to Carl Woese, an American scientist that died in 2012.
