New Sex Roles

Men and women make think similarly about sex: "New data is undermining the evidence that has long been proposed to support the eager males—choosy females paradigm."

"For more than three decades evolutionary psychologists have advanced a simple theory of human sexuality: because men invest less reproductive effort in sperm than women do in eggs, men's and women's brains have been shaped differently by evolution. As a result, men are eager for sex whereas women are relatively choosy. But a steady stream of recent evidence suggests this paradigm could be in need of a makeover. 'The science is now getting to a point where there is good data to question some of the assumptions of evolutionary psychology,' says social psychologist Wendy Wood of the University of Southern California."

Why the ocean you know and love won’t exist in 50 years

  • Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
  • The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
  • If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.

  • Several studies have confirmed that testosterone counts in men are lower than what they used to be just a few decades ago.
  • While most men still have perfectly healthy testosterone levels, its reduction puts men at risk for many negative health outcomes.
