Why do some people with special needs have such similar facial features?
Because people who have the same problem generally have the same cause for that problem. Take, for instance, Down's Syndrome. It's caused by having 3 copies of the 21st chromosome instead of just two.
The Short Answer
Because people who have the same problem generally have the same cause for that problem. Take, for instance, Down's Syndrome. It's caused by having 3 copies of the 21st chromosome instead of just two. Every single person with Down's has this problem, and every single person with this problem has Down's. Along with varying degrees of mental retardation (some people with Down's are just as functional as someone without, others aren't), having trisomy 21 causes the facial features distinctive of the disorder because that's how genes work. If you break the program in the same way, you will get similar results.
