Abstract
Eukaryotic cells are characterized by a considerable increase in subcellular
compartmentalization when compared to prokaryotes. Most evidence suggests that
the earliest eukaryotes consisted of mitochondria derived from an
α-proteobacterial ancestor enclosed within an archaeal host cell. However, what
benefits the archaeal host and the proto-mitochondrial endosymbiont might have
obtained at the beginning of this endosymbiotic relationship remains unclear. In
this work, I argue that heat generated by the proto-mitochondrion initially
permitted an archaeon living at high temperatures to colonize a cooler
environment, thereby removing apparent limitations on cellular complexity.
Furthermore, heat generation by the endosymbiont would have provided phenotypic
flexibility not available through fixed alleles selected for fitness at specific
temperatures. Finally, a role for heat production by the proto-mitochondrion
bridges a conceptual gap between initial endosymbiont entry to the archaeal host
and a later role for mitochondrial ATP production in permitting increased
cellular complexity.
