The women look like THEY share an awful lots of genes!
Then again, some say we all share most of our genes with chimpanzees. I think these young women are plain looking because of the manner of their grooming and dress. Down here we have a lot of Mennonites who are descended from the groups that colonized in Mexico a long time ago, and they follow the traditional customs in how they dress. And though the young ladies all look plain and frumpy from a distance, when you get close to them they are easy on the eyes, and you can tell they take good care of themselves. Not a darn thing wrong with that.
