Being able to draw realistically and use complex grammar are actually controlled by the same 'switch' in our brains.

The Takeaway
By analyzing 77,000 people, researchers found that the ability to depict recognizable figures (like animals or humans) maps directly onto the brain's mechanism for processing complex syntax. This suggests that the sudden appearance of realistic art in human history 45,000 years ago wasn't just a cultural shift, but a direct result of the biological evolution of complex language.
From the abstract
Non-figurative motifs (parallel lines, hand stencils) constitute the earliest known human art, dating to ~400,000 years ago. In contrast, figurative art-depicting recognizable animals and humans-emerges abruptly ~45,000 ya. We hypothesized that this temporal dissociation reflects the sequential evolution of distinct neurocognitive mechanisms underlying language and visual manipulation. Building on our prior taxonomic framework that identified distinct expressive and receptive language mechanisms
