Is potential literacy a genetic trait? Seriously how the hell

IQ is genetic

Developing a written language requires significant capacity for abstract thinking, which is controlled by a specific part of the brain.

>Seriously how the hell was literacy selected for?

Animal tracking. To track an animal in the wild requires the tracker to be smart enough to "read" the environment around him, taking advantage of small clues that the animal has unwittingly left behind. This requires a level of abstract thought that most animals are incapable of, and in time, it ultimately became the defining feature of humans against other species.

You can have a high IQ and not be able to read.

Some people are actually incapable of learning, and others are predisposed to literacy and come to it very easily.

Why? How were the traits or collection of traits that allow humans to construct and decipher written language selected before the advent of the written word?

I'm not really sure you can connect literacy with the ability to make sense of patterns in nature.
