Learning to walk doesn't seem to be particularly easy, having observed the process with my own children. No easier than riding a bike or skating, for which our brains are probably not 'predisposed'.

[nopinsight]

Walking is indeed a complex skill. Yet some animals walk minutes after birth. Human babies are most likely born premature due to the large brain and related physical constraints.

Young children learn to bike or skate at an older age after they have acquired basic physical skills.

Check out the reference to Core Knowledge above. There are things young infants know or are predisposed to know from birth.

[HumanOstrich]

The brain has developed, through evolution, very specific and organized structures that allow us to learn language and reading skills. If you have a genetic defect that causes those structures to be faulty or missing, you will have severe developmental problems.

That seems like a decent example of pretraining through evolution.

But maybe it's something more like general symbolic manipulation, and not specifically the sounds or structure of language. Reading is fairly new and unlikely to have had much if any evolutionary pressure in many populations who are now quite literate. Same seems true for music. Maybe the hardware is actually more general and adaptable and not just for language?

[HumanOstrich]

The research disagrees with you.

Music is really, really old.

And reading and music co-evolved to be relatively easy for humans to do.

(See how computers have a much easier time reading barcodes and QR codes, with much less general processing power than it takes them to decipher human hand-writing. But good luck trying to teach humans to read QR codes fluently.)

What makes you think so? Humans came up with biking and skating, because they were easy enough for us to master with the hardware we had.
