Biological Classification - The Three Domains of Living Things

The video explains the evolutionary divergence of life into three domains: bacteria, archaea, and eukarya. Bacteria and archaea are similar as prokaryotes with non-nucleated cells, while eukarya have distinct nuclei. Archaea differ from bacteria by possessing genes and pathways similar to eukarya and include extremophiles that thrive in extreme conditions. Eukarya are mostly multicellular and diverse, including familiar organisms like plants and animals.

What are extremophiles and why are they significant in the archaea domain?

Describe the diversity of the eukarya domain and give examples of organisms found within it.
