abstract: The origin of the eukaryotic cell, with its compartmentalized nature and
generally large size compared with bacterial and archaeal cells, represents a cornerstone
event in the evolution of complex life on Earth. In a process referred to as eukaryogenesis,
the eukaryotic cell is believed to have evolved between approximately 1.8 and 2.7
billion years ago from its archaeal ancestors, with a symbiosis with a bacterial
(proto-mitochondrial) partner being a key event. In the tree of life, the branch
separating the first from the last common ancestor of all eukaryotes is long and
lacks evolutionary intermediates. As a result, the timing and driving forces of
the emergence of complex eukaryotic features remain poorly understood. During the
past decade, environmental and comparative genomic studies have revealed vital details
about the identity and nature of the host cell and the proto-mitochondrial endosymbiont,
enabling a critical reappraisal of hypotheses underlying the symbiotic origin of
the eukaryotic cell. Here we outline our current understanding of the key players
and events underlying the emergence of cellular complexity during the prokaryote-to-eukaryote
transition and discuss potential avenues of future research that might provide new
insights into the enigmatic origin of the eukaryotic cell.
