Sex redefined : Nature News & Comment

The idea of two sexes is simplistic
Biologists now think there is a wider spectrum than that

From the February 18, 2015 Nature News Feature

““The main problem with a strong dichotomy is that there are intermediate cases that push the limits and ask us to figure out exactly where the dividing line is between males and females,” says Arthur Arnold at the University of California, Los Angeles, who studies biological sex differences. “And that’s often a very difficult problem, because sex can be defined a number of ways.”

The article goes on to explain DSDs (Differences/Disorders in Sexual Development) both in and out of the womb.

New book busts myths about sex, race and violence

From the 9 May 2012 Eureka News Alert

here are three pervasive myths about human nature centered on sex, aggression and race. They are:

  1. Men and women are truly different in behavior, desires and wiring.
  2. Humans are divided into biological races (white, black, Asian, etc.).
  3. Humans, especially males, are aggressive by nature.

 

A new book by University of Notre Dame Anthropology Professor Agustín Fuentes titled “Race, Monogamy, and Other Lies They Told You: Busting Myths about Human Nature” (University of California Press, 2012) counters these pernicious myths and tackles misconceptions about what race, aggression and sex really mean for humans.

Presenting scientific evidence from diverse fields, including anthropology, biology and psychology, Fuentes incorporates an accessible understanding of culture, genetics and evolution, requiring us to dispose of notions of “nature or nurture.”

Fuentes devises a myth-busting toolkit to dismantle persistent fallacies about the validity of biological races, the innateness of aggression and violence, and the nature of monogamy and differences between the sexes. He includes a list of the most common misperceptions about human nature on race, sex and violence, and counters those myths with a myth buster….

The Misperception of Sexual Interest

Summary from the 2011 Psychological Science article at http://homepage.psy.utexas.edu/homepage/group/busslab/pdffiles/The%20Misperception%20of%20Sexual%20Interest.pdf

In the current study (N = 199), we utilized a speed-meeting methodology to investigate misperceptions of sexual interest. This method allowed us to evaluate the magnitude of men’s overperception of women’s sexual interest, to examine whether and how women misperceive men’s sexual interest, and to assess individual differences in susceptibility to sexual misperception. We found strong support for the prediction that women would underestimate men’s sexual interest. Men who were more oriented toward short-term mating strategies or who rated themselves more attractive were more likely to overperceive women’s sexual interest. The magnitude of men’s overperception of women’s sexual interest was predicted by the women’s physical attractiveness. We discuss implications of gender differences and within-sex individual differences in susceptibility to sexual misperception.
