So, HAR123 plays a crucial role in the ratio of neurons and glial cells. So, one very important thing, HR123 does is promote an advanced human trait referred to as cognitive flexibility. And this is the ability to unlearn and replace previous knowledge. And the research also gave a molecular explanation for some radical changes that have happened in the human brain over the course of revolution. So, further research is needed to help fully examine just how much influence the HAR123 has on specific neural human traits. And for some reason or another, that same molecule in chimps doesn't have the same effect on their genes as it does on ours.
