Comb jellies take their place on the oldest branch of the animal family tree.
Polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), function in both enzymatic and nonenzymatic pathways to regulate gene expression.

Is nutrient chemical uptake, as occurs with the ingestion of these fatty acids, responsible for de novo gene expression in the non-human primate to human brain that is controlled by nutrient chemical metabolism to pheromones? If so, adaptive evolution of our brain and behavior appears to be nutrient chemical-dependent and pheromone-controlled as is behavior in species from microbes to man via ecological, social, neurogenic, and socio-cognitive niche construction.
