The voles' pair bonding, sharing of parental roles and egalitarian nest building in couples makes them a good model for understanding the biology of monogamy and mating in humans
A good model for ideal human behavior, sure, but actual behavior?!? One wonders if the researchers have met any actual human couples.
Of course they haven't met actually human couples. They're researchers.
I do basic IT admin work and I haven't gone out and gotten a degree. Just a long list of job related work experience. However I work in an region of the U.S. where a degree isn't going to help much anyway because there aren't high paying IT jobs unless I want to commute 2 hours every day.
The point is. Sometimes experience outweighs a degree. Sometimes you need to know math. It all depends on what you want to do.
