The origins of phagocytosis and eukaryogenesis

Natalya Yutin, Maxim Y Wolf, Yuri I Wolf, Eugene V Koonin Biology Direct 2009, 4:9 (26 February 2009)

Archaeal ancestors of eukaryotes might have possessed a primitive, actin-based cytoskeleton that would facilitate engulfment of bacteria, in particular, the proto-mitochondrial endosymbiont.

Origin of the nucleus and Ran-dependent transport to safeguard ribosome biogenesis in a chimeric cell

Gáspár Jékely Biology Direct 2008, 3:31 (24 July 2008)

Nuclear compartmentalization in eukaryotes evolved via the coevolution of Ran and karyopherin dependent transport, nuclear membranes and nuclear pore complexes in order to reduce the number of chimeric ribosomes which formed after the acquisition of the protomitochondrium.

The Last Universal Common Ancestor: emergence, constitution and genetic legacy of an elusive forerunner

Nicolas Glansdorff, Ying Xu, Bernard Labedan Biology Direct 2008, 3:29 (9 July 2008)

This article is part of a collection on Origin and early evolution...

The Last Universal Common Ancestor developed in a protoeukaryotic, promiscuous and genetically redundant community of cells with a broad, moderate thermal profile and an RNA genome enclosed in a protonucleus.
