From what I know, I think intelligence evolved as a result of us being fragile relative to other animals. Our offsprings are completely helpless for the first year. We aren't as fast, strong, or resilient as most wild animals; So we had to compensate with something. Our total weakness pushed us to use our brain to survive. For example, open confrontation without a plan, even with a pray animal like deer, would result in a total failure. Yes, we are in part endurance hunters, but no amount of endurance would help with something that's categorically faster than you. So we hunted in groups, using tools and schemes to survive. And here we are now. Conversations about intelligence, imo, often miss an important caveat. Humans have a unique ability of plasticity, this constant adaptation and growth that all of us are capable of in a single lifetime. I'm of opinion that if you are capable of speaking a language, that means you are capable of learning and understanding anything. Information, ultimately, is causal relationships and compositions; The more you can see and meaningfully categorise given the circumstance, the more 'intelligent' you are; More specifically - how much can you transcend your cognitive barriers - the way things can be thought of, [permissible/assumed to be valid] modes of engagement with what you experience so to speak. We sometimes corner ourselves into limitations to maintain a sense of comfort, validity, and alignment with what we think "actually is"; Rather than accepting and understanding things as they are without any stakes and generalisations. Point I'm trying to make is, sometimes intelligence is stagnant due to inner dissonance, conflict, alterior to understanding motives. Apart from complex motivations varying from person to person, things like malnutrition, and trauma that takes up cognitive bandwidth and sets limits on cognition, also affect us; What we even think of as good and bad, everything we are that we accumulate over the time of being alive - affect the way we think about what we are experiencing. Let's not forget the effects on who you are during developmental period in womb and the circumstance of said womb (overall hormonal and chemical circumstance). I believe, in some cases, we are eager to explain intelligence away as mostly genetic because it's easier to understand variance that way, rather than having to swift through circumstantial nuances and complexity; Sometimes as means of not changing anything about ourselves and our conduct with eachother, the way we organise; Sometimes to maintain a sense of superiority and inferiority relative to others. List goes on.
