Elon then backs it up with his conversation with GROK clarifying that’s he’s also taking about humans not just Pitbulls:
Yes. Twin, adoption, and family studies consistently show that genetic factors account for a substantial portion of individual differences in aggressive and violent behavior in humans, with heritability estimates typically around 40–60% (often ~50%). pmc.ncbi.nlm.nih.gov
This means that genetic variation contributes meaningfully to differences in propensity for aggression across people, while the remaining variance is largely explained by non-shared environmental factors (unique experiences). Shared family environment tends to play a smaller role, especially later in life. These estimates hold across sexes and various measures of aggression (physical, reactive, proactive, antisocial behavior), though they can vary somewhat by age, form of aggression, and assessment method. sciencedirect.com
Conclusion :
Genetics influence propensity or risk, not destiny. Environment, development, culture, and individual choices play major roles, and most people with higher genetic risk never engage in serious violence. No single gene or simple genetic test predicts violent behavior reliably in individuals. Phenotypes are heterogeneous (everyday aggression vs. severe criminal violence), and studies face challenges with measurement, sample size, and replication.
In short, the scientific literature from behavioral genetics provides clear evidence of a genetic contribution to differences in violence and aggression propensity, alongside strong environmental moderation. Molecular mechanisms are still being mapped and remain incomplete.

Thoughts ? Is it over for BBC copers ? @IronMike in disbelief
