A study in Evolutionary Psychology found when individuals were asked what they wanted in a partner, the majority said they would prefer a complementary partner rather than a similar one.
"In thinking about this…we wanted to use an evolutionary argument to figure out what is the simplest animal to sleep.
Instead they argue that this is an evolutionary development, and similar to primates, mechanisms in the human brain have had to develop to react very quickly to these potentially dangerous threats.
They mapped the distribution of these features on to the evolutionary tree of flowering plants enabling them to build a picture of what flowers looked like at key points in their history - including the last common ancestor of all living flowers.
Your appendix might not be a useless evolutionary byproduct after all.
This finding is supported by research suggesting that those who create new evolutionary patterns (compared to those who stick with the normal patterns developed by our ancestors) are the most progressive.
Scientists believe the attachment system is an evolutionary process that humans developed to survive.
The research is published in the journal Frontiers in Evolutionary Neuroscience.
The Karolinska Institute researchers says this makes sense in evolutionary terms.
'From an evolutionary perspective, we evolved under very dirty conditions and maybe this desire to keep our environment and our behaviours sterile isn't actually working to our advantage.
This isn't a philosophical cri de coeur; it's an evolutionary conundrum.
The myth was started in the 1920s by a psychologist, Floyd Allport, whose evolutionary spin job was attributed to Darwin, thus launching nearly a century of misguided beliefs.

Geoffrey Miller, an evolutionary psychologist at the University of New Mexico, has proposed a disturbing answer.
This finding is supported by research suggesting that those who create new evolutionary patterns (compared to those who stick with the normal patterns developed by our ancestors) are the most progressive.
"In evolutionary time, this is a blink of an eye.
This finding may pave the way for the detailed study of the neural substrates underlying other domain-specific anhedonias and, from an evolutionary perspective, help us to understand how music acquired reward value.
"It could be that we are so busy with our lives, we are so embedded in our technological narrative that the idea of engaging in long-distance sex and robot sex is actually a natural process in our evolutionary cycle," she said.
A leading evolutionary biologist, Professor John Wiens, found that 47 percent of nearly 1,000 species had suffered local extinctions linked to climate change with populations absent from areas where they had been found before.
