I love everything related to the topic of genetics, and this is one of the most interesting articles I've read lately. I found specially amazing that Minnesota experiment with the twins.
I'll make sure to show this to my mother, guess I owe her even more than I thought. For my genes, and for teaching me to always value brains and personality over beauty on my romantic partners.
Sorry for getting back to you'in time'! been some what taken away!
Otherwise thanks for your thoughts @mike961. It is true, we owe out mothers a lot more
