Old & Odd: Archaea, Bacteria & Protists - CrashCourse Biology
Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most...
