Swarming among unicellular organisms often precedes sexual reproduction because it rapidly increases population density in a small area, whereas it would be much rarer for two choanoflagellates to spontaneously encounter each other and mate under normal conditions.
The King lab at Berkeley has pioneered the exploration of the origins of multicellularity by looking at choanoflagellates for shared characteristics and behaviors conserved by evolution in animals.
The choanoflagellates, for their part, may use high concentrations of EroS as a sign that conditions are suitable for sexual reproduction — though why that is so remains unknown.
Choanoflagellates produce a large number of tyrosine kinases, molecular signals essential for intercellular communication in animals.
For example, the insulin receptor substrate and phosphotyrosine binding proteins GAB1 / GAB2 emerged on the metazoan stem after the divergence of choanoflagellates, indicating that an insulin - signalling - like pathway may have been a key regulator of growth in early animals by tying into the ancient PDK1 and Akt kinases (Fig. 2b).
For example, 28 % of the amino acid substitutions between humans and their last common ancestor with choanoflagellates occurred on the metazoan stem lineage (bold line in Fig. 1d), before the divergence of sponges from other animals.
