Small-Scale Question Sunday for March 9, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Human babies are actually pretty middle of the pack in terms of self-reliance for mammals- calves can walk, but new puppies can’t see or hear.

There are biological limitations on how much more precocial human babies can be without killing the mother in the process of birth. I suspect we’re pretty close to them, and genetic engineering would be better aimed at faster development in the first year or two.

Of course if you’re trying to decant supermen, fully grown, I’d say… about three in terms of development. Able to comprehend language, the toilet, feeding themselves, etc. You know, you’d still have to teach them those things. ‘Using a spoon’ and ‘going in the toilet instead of wherever’ and ‘the English language’ are not instincts and it’s probably impossible to make them instincts.

and ‘the English language’ are not instincts

Yes, you're correct, though proclivity toward English is almost certainly there in the genes. Which I mention because I think it's so cool and a window into so much else.

proclivity toward English is almost certainly there in the genes.

Why is this almost certain?

Inasmuch as 'being good with a given language' is under selection pressure, populations will evolve to be better at that language.

To summarize, this study revealed the genetic basis of Chinese and English abilities in a group of Chinese bilingual children.

There's more research on this sort of thing but it's difficult to find and often gets disappeared.

The problem is that English today isn't the same as "English" circa AD 1000, so it's not clear to me why there would be a long lasting coherent selection pressure. In fact, English today is a result of changes made to the language by its speakers over the past thousand years, so it's really not clear which way causality even runs.

I'd be much more interested in a survey of English ability of third generation Chinese immigrants in the US rather than bilingual kids in a bilingual country. I strongly suspect that the effect will be small or even in the other direction due to Asian IQ.

Selection doesn't require a thousand years. It happens in each generation. And particularly with industrialism and a shift to an information economy, it's going hard. Besides which, English and Chinese are a lot more like their thousand year old selves than they are like each other. So, sure, call the matter directional.

Statements like this freak me out. Of course it's both! You might like this: https://www.pnas.org/doi/10.1073/pnas.0610848104
