I don't understand your point here. Of course those things were developed due to competency, but at the same time that white male scientists and technicians were working on them women were mostly not even allowed to go to college or to study those areas - much less to work in them, and neither were a whole bunch of other people due to traits that having nothing to do with intelligence or capabability such as gender, race and religion. Nonetheless, a huge number of scientific discoveries and technological advances - to say nothing of most household appliances - were invented, discovered, or developed by women and minorities. So, it's not that these other people aren't also quite competent - it's that their full participation in these areas was significantly hindered by both law and custom - and that the legacy of those laws and customs lives on today in unconscious bias and even in some cases, outright discrimination and disbelief in the competence of anyone other than white men. That's not a meritocracy.
In addition, there's this dynamic:
“Advantages beget advantages. Those who are born in the upperclass echelons are likely to remain in the upper class (Wilkinson & Pickett, 2009). The majority of individuals who work at elite and prestigious firms tend to come from elite educational institutions (Rivera, 2016). And high-earning entrepreneurs disproportionately originate from highly educated and well-to-do families (Levine & Rubinstein, 2013). These are some examples of how advantage tends to be self-perpetuating, belying the American ideal of social mobility (e.g., Hochschild, 1996).”

I recommend that you read the stories I've already linked to you in order to improve your understanding of the topics you are attempting to discuss.
As to lobsters, here's an excerpt from a very good article that explains clearly that Peterson doesn't know what he's talking about.
"While lower levels of serotonin are associated with decreased levels of aggression in vertebrates like the lobster, the opposite is true in humans. (emphasis mine) This happens because low levels of serotonin in the brain make communication between the amygdala and the frontal lobes weaker, making it more difficult to control emotional responses to anger."
