Human Brain Evolution Linked to Autism Rates
Genetic changes that made our brain unique also made us more neurodiverse, linking autism to human evolution.
Why it matters
- Links autism prevalence to human brain evolution.
- Provides insights into neurodiversity and brain development.
By the numbers
- 1 in 31 U.S. children diagnosed with autism (3.2%).
- Worldwide prevalence: ~1 in 100 children.
The big picture
- Rapid evolution in specific neurons linked to autism genes.
- Changes may be due to natural selection unique to humans.
What they're saying
- Comments discuss environmental factors and cultural impacts.
- Study published in Molecular Biology and Evolution.
Caveats
- Evolutionary benefits of genetic changes remain unclear.
- Study does not offer medical advice.
What’s next
- More research needed on evolutionary benefits.
- Explore environmental and cultural impacts on autism.
