Mutations in genes known as ADRB1 and DEC2 do indeed exist, and they give the bearers a permanent reduction in amount of time they need to sleep. It is suspected there are more.
I guess my question is: is there a similar genetic basis for ability to hyperfocus for long periods of time without fatigue? Or is it purely something that is developed.
ADHD is likely partly genetic. Savant syndrome is maybe genetic or at least acquired early.
Just requiring less sleep is still a huge advantage though.
