"The regions that pack the most punch, according to Michaelson, are among the most ancient parts of our genome—having evolved before modern humans split from Neanderthals. Scientists call these genetic regions human ancestor quickly evolved regions (HAQERs)."
"It's not very much of the genome, Michaelson says, explaining that these regions account for around a tenth of a percent of our DNA. But we found that a huge amount of the genetic variation that explains individual [language] differences was in there."
Research indicates that while the FOXP2 gene is associated with language abilities, it is not the sole factor. New findings reveal that ancient genomic regions, termed human ancestor quickly evolved regions (HAQERs), significantly influence language skills. These regions, which evolved before the divergence of modern humans and Neanderthals, account for a small fraction of the genome but contain substantial genetic variation related to language differences. A study involving 350 students showed a correlation between these ancient regions and language ability over time.
