Tracing the Evolution of Behaviour: Machine Learning Decodes Nematode Aggression
Researchers employed machine learning to analyse predatory aggression in the nematode Pristionchus pacificus, linking specific behaviours to modifications in octopamine and tyramine neural circuits. The study suggests that evolutionary rewiring of ancient noradrenergic pathways facilitated the emergence of complex predatory traits.
