Happy to see this set full of curious characters! I choose the fisherman as the #1.
This family members IQ, I bet, is higher than average one. Any ideas why it may be so?
Nature always creates a spectrum: from the shortest to the tallest, from the dumbest to the smartest. So the best combinations for certain ecosystems survive and thrive. That's the first layer. The second layer for a species is groups (populations).
Culture is another reality of natural selection.
Nature's hard disks are DNAs, and culture's hard disks are the minds of human groups carrying some form of culture (institutions). The family is the most basic institution, the oldest form of cultural hard disk, the most rooted in nature. Religions and nations (as carriers of national traditions) are other layers of culture.
Culture is another field of experimentation and natural selection. Culture also creates a spectrum: from the shortest to the tallest, from the dumbest to the smartest. So the best combinations for certain ecosystems survive and thrive.
So, some families are smart because they have better hardware (genes) and software (culture as the family tradition) for being smart. Some family traditions speak openly: "dear growing organisms, we are not those donkeys, we are the smart breed". Strength is also about culture, not only nature. Some families instill in children the desire for big muscles.
Fantastic answer; the case when comment is better than the post itself xD
Happy you enjoyed the visuals, thank you! 😃
