I used to climb towers for a living. Never thought I’d be into it but I actually really liked it and wish I’d started earlier in life and kept at it longer. Can guarantee the only high IQ involved a tape measure and a bad pun.
I suspect it’s worse than that: most people have multiple natural talents they never discover. That is why I encourage my kids to try all kinds of experiences, and not label themselves as “not a science person” or “not outdoorsy”. You don’t need to be good at just one thing.
The seal thing isn’t a huge surprise; they need a lot of fine nose control to swim and hunt efficiently. The same way we need hand eye coordination and can balance balls with our hands.
