| what _a_ Denisovan looked like with any accuracy.
|
| For modern human individuals it's pretty limited to 'obvious'
| traits like eye color, hair color, and skin color.
|
| There was some projects that tried to chart beyond that, but

| You might be able to pick someone out of a hundred with that
