The science on this stuff is pretty new and far from settled. Even Dr. Soh hedges by writing "research _suggests_" -- and then, bafflingly, makes strong claims about human male behavior based on the conclusions of a review on _rodent_ studies (see her link):

"Available data from rats, mice, and ferrets point to the importance of perinatal exposure to steroid hormones in the development of partner preferences, as well as the importance of activational effects in adulthood."

"Additional paradigms that address these questions are needed for better understanding of partner preferences in rodents."

By all means, let's continue the research .. but in the meantime, if the G&M is going to have Dr. Soh making strident claims on the basis of her expertise in the field, she should be able to provide better citations than these.
