Eukaryotes (gray branch) are suggested to have emerged
from the Asgard archaea upon
endosymbiosis with an alphaproteobacterial partner (the mitochondrial endosymbiont).
Excitingly, these proteins are functionally enriched for membrane bending, vesicular biogenesis, and trafficking activities, suggesting that eukaryotes evolved
from an archaeal host that contained some key components that governed the emergence of eukaryotic cellular complexity after
endosymbiosis.
Other eukaryotic organelles may have also evolved through
endosymbiosis; it has been proposed that cilia, flagella, centrioles, and microtubules may have originated
from a symbiosis between a Spirochaete bacterium and an early eukaryotic cell, but this is not yet broadly accepted among biologists.
In general, they are considered to have originated
from cyanobacteria through
endosymbiosis.
This
endosymbiosis, or symbiotic merging of two cells, enabled the evolution of a highly stable and successful organisms with the capacity to use energy
from sunlight through photosynthesis.
This is the so - called serial
endosymbiosis theory of a monophyletic origin of the mitochondrion
from a eubacterial ancestor.
Instead, some eukaryotes have obtained them
from others through secondary
endosymbiosis or ingestion.
We humans have descended
from organisms that adapted to living in a prokaryotic world, and we humans retain (conserved in evolutionary terms) in our Eukaraotic mitochondria the cellular machinery to power our cells that we inherited (i.e.,
Endosymbiosis)
from the prokaryotes of deep time on earth.
Here, I developed a strong interest in a variety of topics that center around this theme, ranging
from the origin of the eukaryotic cell to
endosymbiosis and evolution of whole microbial populations.
These similarities have prompted the hypothesis that mitochondria are derived
from bacteria, by a process termed
endosymbiosis.
by Lynn Margulis Drama: A tale of atmospheric scientists
from the founder of the
endosymbiosis theory, via an ultimately unsatisfying symbiosis of fiction and autobiography.
