The Season of Sex: Why Sexual Activity Peaks in the Summer

The Season of Sex: Why Sexual Activity Peaks in the Summer

In the animal kingdom, there are some species that only mate seasonally. They do it just a few times per year, coinciding with their fertile periods. Humans, by contrast, are what scientists call "continuous breeders," meaning they are able to mate all year-round. However, the term "continuous breeders" masks the fact that humans' mating patterns still follow a very reliable seasonal pattern. Specifically, we tend to have more sex in the summer than we do at any other time of year.

The Science Behind Men’s Attraction To Women's Rear Ends

The Science Behind Men’s Attraction To Women's Rear Ends

Evolutionary psychologists have long argued that many of the physical features heterosexual men are drawn to in women reflect traits that signify female health and fertility status. The basic argument is that our male ancestors developed an attraction to these traits because it enhanced their odds of reproductive success. These mating preferences are thought to have been passed down across generations and still influence what men are attracted to today on some primal level. In a new study just published in the journal Evolution and Human Behavior, researchers examined whether men’s attraction to women with more prominent rear ends might represent one such evolved mating preference.

Can Previous Mating Partners Influence The Traits Of Future Offspring?

Can Previous Mating Partners Influence The Traits Of Future Offspring?

Centuries ago, Aristotle proposed the concept of telegony, which suggests that the traits of offspring are not only influenced by their biological parents, but also by the mother’s former mates. This idea never really caught on with scientists, though, because it failed to generate much empirical support. Indeed, so little evidence has been found for it that some encyclopedic descriptions of telegony chalk it up to nothing more than “superstition.” However, a new study just published in the journal Ecology Letters provides some provocative experimental support for telegony and suggests that we may have been too quick to dismiss this idea

Will Dancing Get You Laid? (VIDEO)

Will Dancing Get You Laid? (VIDEO)

“Why are we so drawn to dance, and is it really equivalent to a human mating call? More importantly, does dancing increase your potential to ‘get some?’”

In the fascinating video below, the folks over at ASAP Science take a look at the science behind dancing and come to the conclusion that our groovy might have evolved to serve a very important purpose. In fact, it was Darwin who first suggested that dance might represent some human mating ritual that has implications for survival and reproduction. How so? Dancing may be one very visible way of demonstrating your genetic fitness to potential mates. And we aren’t the only species that does this—some animals and insects also use dance to communicate their sexual desirability.

What's The Recipe For A Hit Song? Lyrics About Reproduction

Evolutionary psychologists believe that men and women have evolved fundamentally different mating strategies in order to maximize the chances of passing along their genes to future generations. It is theorized that men developed a tendency to pursue short-term sexual encounters with young and curvy women, whereas women developed a tendency to hold out for long-term relationships with reliable men who have the resources necessary to take care of them and any offspring they might produce [1]. There is a substantial amount of research supporting the idea that men and women are looking for different things in their mates and these preferences generally fall along the lines predicted by this theory; however, a recent set of studies suggests that these tendencies are so deeply ingrained that we may have even developed a preference for popular media that reinforces these sexual strategies.

Featured Book Series: Sex at Dawn

A brand new addition to the blog is the Featured Book Series, in which I will review and analyze books relevant to human sexuality that I hope will be of interest to readers. Think of this as an opportunity to get some ideas for summer reading material, as well as an opportunity to participate in a virtual book club (discussion is encouraged!). I’m kicking things off with Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships (2010; Harper Collins). I realize this isn’t a new book and some of you may already be familiar with it, but I’m starting here because it is fresh in my mind from having assigned it in my Human Sexuality course this past semester. This is actually the very first time I have assigned a mass-market paperback as reading material in a college course, which should tell you that this is a book I think is definitely worth checking out.
