Lars PenkeImpressive new study by Kate Laskowski, Max Wolf and colleagues:
Genetically identical fish from mothers reared in near-identical environments show reliable behavioural differences from day 1 after birth, stable and increasing over 10 weeks in near-identical environments.
Supporting that there is a variance component in behavioural development beyond genes and environment (stochasticity / chance / noise) that we will never be able to explain. Certainly not in humans.
The emergence and development of behavioral individuality in clonal fish - Nature Communications
You’re unique just like everyone else. But when does such individuality appear? Laskowski et al. find that clonal fish show unique behavioral patterns on their first day of life, and these patterns predict their behavior up to at least 10 weeks later.
