About 600 million years ago, chytrids live in moist and watery environments. They are living fossils in the sense they reproduce with sperm-like cells that can swim to a new area.

About 1.15 billion years ago, our animial-fungi ancestor evolve a true posterior flagellum. Single-celled animal sperm has a lineage back to this ancestor.

About 950 million years ago, fungi ancestors evolve into multiple early-diverging lineages with flagellated spores: chytrid-like forms.

About 1.3 billion years ago, our animal-fungi ancestor stopped using two pulling flagella and narrowed it down to a single motor.

About 2.4 billion years ago, Cyanobacteria “hacked” the sun to split water, releasing oxygen as a byproduct and triggering the first global environmental catastrophe and subsequent biological reset.

About 3.72 billion years ago, right after LUCA, when cells emerged, touch became the most ancient form of biological sensing: required to physically navigate reality.

All life today are either Prokaryote or Eukaryote. Around 2 billion years ago, Eukaryotes evolved from Prokaryotes. The evolutionary leap to eukaryotes introduced cells with a nucleus and membrane-bound organelles, a complex architecture derived from prokaryotic predecessors through endosymbiosis. This process, crucial for eukaryotic evolution, involved the incorporation of prokaryotic cells into the cytoplasm of

Prokaryotes are nucleus-free cells that include both bacteria and archaea — the two lineages that split shortly after LUCA.
