Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about.
Ok maybe, but it doesn’t really say much, its already well established that autism/adhd/etc can be passed down.
I believe most labels are just groupname for a specific set of neurodivergent features. And those features are the result of minor ways peoples brain differ from dominant norm. If all dna followed the dominant norm we would be identical and evolution would come to a halt.
Many neurodivergent people are capable of leading healthy lives and getting children. There are often advantages that cancel out the negatives. So those differently evolved features are not disappearing and instead getting passed on through generations almost becoming some form of neurological race.
The study would be way more remarkable if they could proof that some enfants avoid faces with no possible influenced by their genes.
