Line of descent
Schleiden, Schwann, and Virchow are all three associated with the cell theory.
There are no women scientists associated with cell theory because the boys are being sexist.
The Ancestor Cell was created in 2000.
Well, through the theory of evolution, all lifeforms have evolved from a single cellular common ancestor. I'm not sure if certain um [reproductive substances?] are single cellular, but I assume that each creature on the planet has to have developed from dividing cells.
The name of the theory that Schleiden and Schwann developed is the cell theory.
Mitochondria are believed to have originated from an ancient symbiotic relationship between a primitive eukaryotic cell and an aerobic prokaryotic cell (likely a bacterium), where the prokaryotic cell was engulfed by the ancestral eukaryotic cell and eventually evolved into mitochondria. This theory is known as the endosymbiotic theory.

The cell was not invented by a single person, but rather the cell theory was developed by multiple scientists including Matthias Schleiden, Theodor Schwann, and Rudolf Virchow in the 19th century.
they official formulated the cell theory in 1665
The two main theories of hematopoiesis are the monophyletic theory, which suggests that all blood cells arise from a common stem cell, and the polyphyletic theory, which proposes that different blood cell lineages have separate origins. Recent evidence supports the monophyletic theory, where a single hematopoietic stem cell gives rise to all blood cell types through a hierarchical differentiation process.
The general theory was that everything (humans included) come from a common ancestor. This makes sense if one was to believe in the cell theory (all existing cells come from previous cells, therefore everything in the world had to start with a single cell, our common ancestor). You need to know the general theory to understand the theory as it regards to humanity. The theory regarding humanity still stands that we all come form one ancestor. but it focuses more on the human aspect. Here it states that we evolved along with primates, (we share the same ancestor as monkeys, apes, etc.). The theory particularly states that humans evolved from ancient primates over the course of over 250,000 years to become what we are today. Fast fun fact Charles Darwin did not come up with the theory of human evolution, he only said something akin to "light will shed upon the origin of man" saying nothing that men came from apes or ancient primates.
