Life on Earth is basically photosynthesis (in the ocean) turned into mass (on land)

 

 humans are cranking out gigatons of carbon as co2 and methane emissions! oops. We are converting "stored photosynthesis" as ancient life - oil and coal - into emissions of entropy!

 Phytoplankton are plant-like microscopic organisms that drift in water. While often referred to as "tiny plants," they are not true plants; instead, they primarily consist of single-celled algae, protists, and photosynthetic bacteria

 In spite of Ocean mass being very small (both as total percentage and individual size) - there is a HUGE photosynthesis conversion in the ocean - 50% of Earth photosynthesis...

The function of photosynthesis is HUGE but the life has a very fast turn over time as single-cell organisms....

 

 Almost ALL the biodiversity of life on Earth is in single-cell bacteria organisms!!

 Eukaryotes are a subset of archaea because genetic and evolutionary analyses show that eukaryotic cells evolved from within the archaeal lineage. Instead of being a completely separate and ancient "third domain" of life, eukaryotes are specialized descendants of an archaeal ancestor that merged with a bacterium

 Genetic Machinery: The cellular systems responsible for reading DNA (transcription and translation) in eukaryotes are strikingly similar to those in archaea. Both use similar enzymes (like RNA polymerase) and protein machineries

 Histone Proteins: Eukaryotes wrap their DNA around proteins called histones to organize it. Archaea are the only other group of organisms that use histone-like proteins for the same purpose. [1, 2]
  • The Asgard Connection: Discoveries of "Asgard" archaea (like the Lokiarchaeota) have revolutionized evolutionary biology. These deep-sea microbes contain "eukaryote signature proteins" (ESPs) that govern cell shape, internal trafficking, and structural support
  • eukaryotes inherited their core genetic and information-processing machinery directly from archaea, they aren't purely archaeal. Roughly two billion years ago, an ancestral archaeon engulfed an aerobic bacterium. Instead of digesting it, the host formed a symbiotic relationship with it. This bacterium eventually evolved into the mitochondrion—the power plant of the eukaryotic cell. This event also triggered the evolution of the defining feature of eukaryotes: the nucleus
  •  Because the host cell's DNA originated entirely inside the archaeal tree, cladistically speaking, Eukaryota is simply a highly complex and specialized branch inside the Archaea domain

     

  • Domains: All life is divided into three domains: Bacteria, Archaea, and Eukarya.
  • Kingdoms: Kingdoms subdivide these domains. For example, the domain Eukarya contains four kingdoms: Animalia, Plantae, Fungi, and Protista
