Monsterhood need not be anatomically obvious.
Autism is another form of monsterhood.

Gay men and straight women share brain detail
Tue Jun 17, 2008 7:49am BST
LONDON (Reuters) - Gay men and straight women share some characteristics in the area of the brain responsible for emotion, mood and
anxiety, researchers said on Monday in a study highlighting the potential biological underpinning of sexuality.
Brain scans also showed the same symmetry among lesbians and straight men, the researchers wrote in the Proceedings of the National
Academy of Sciences.
"The observations cannot be easily attributed to perception or behavior," the researchers from Sweden's Karolinska Institute wrote.
"Whether they may relate to processes laid down during the fetal or postnatal development is an open question."
A number of studies have looked at the roles genetic, biological and environmental factors play in sexual orientation but little
evidence exists that any plays an all-important role. Many scientists believe both nature and nurture play a part.
Brain scans of 90 volunteers showed that the brains of heterosexual men and homosexual women were slightly asymmetric with the right
hemisphere slightly larger than the left, Ivanka Savic and Pers Lindstrom wrote. The brains of gay men and heterosexual women were
not.
Then they measured blood flow to the amygdala -- the area key for the "fight-or-flight" response -- and found it was wired in a
similar fashion in gay men and heterosexual women as well as lesbians and heterosexual men.
