No matter what your perspective is on love and attraction, it always seems to come down to men having a tendency to look for partners who are younger and more physically attractive, while women tend to look for partners who are older and more financially stable. I know — this news is stunning, but what’s even more surprising is that these preferences have their roots in evolution. RELATED: 20 Ways To Let A Guy Know You Like Him (In A Subtle, Flirty Way)

Here’s what men and women look for in a mate, according to evolution.

In 2015, researchers from the University of Texas at Austin studied 4,764 men and 5,389 women from 33 different countries and 37 different cultures. The subjects were given 18 possible characteristics of a mate and were then asked to rate those characteristics. Across the board, both genders put love, a dependable character, emotional stability, and a pleasing disposition first, and it wasn’t until number 5 that men and women started to differ in their choices. Here’s how it went down between the two genders: What men look for in women:

The study’s lead author, Daniel Conroy-Beam, said about the results, “The large overall difference between men’s and women’s mate preferences tells us that the sexes must have experienced dramatically different challenges in the mating domain throughout human evolution.” RELATED: 7 Subtly Brilliant Ways To Get A Man To Do Anything You Want And the study’s co-author, David Buss, explained that, “Many want to believe that women and men are identical in their underlying psychology, but the genders differ strikingly in their evolved mate preferences in some domains. The same holds true in highly sexually egalitarian cultures such as Sweden and Norway as in less egalitarian cultures such as Iran.” Conroy-Beam added, “Because women bear the cost of pregnancy and lactation, they often faced the adaptive problem of acquiring resources to produce and support offspring, while men faced adaptive problems of identifying fertile partners and sought cues to fertility and future reproductive value. Few decisions impact reproduction more than mate choice. Mate preferences will therefore be a central target and driver of biological evolution. We have found some promising initial results, and we think this holistic approach will help answer a lot of questions in mating research in the future.” Evolutionary psychology predicts that men and women tend to have consistently different mating strategies because of one simple fact: women get pregnant and men don’t. This incredibly basic asymmetry means that men and women face different challenges in regard to reproductive fitness, or the number of offspring produced by an individual. So, in the end, it all seems to boil down to keeping the human race going. RELATED: 12 Ways To Make Him Think About You — All The Time Christine Schoenwald is a writer and performer.
