Research on Mate Selection Shows That Settling for 'Mr. Right Now' is better than waiting for 'Mr. Right.'

Research on Mate Selection Shows 
That Settling for 'Mr. Right Now' 
is better than waiting for 'Mr. Right.'

And that if we were raised in small communities we are more risk averse and more likely to settle and find a mate. This makes sense to me. It indicates that if there are more possible mates when we are growing up we think there are more fish in the sea and it's harder for us to find someone we want to mate with for life. Though it talks about how we grew up and I also think it explains why people searching for a mate on dating sites like Match.com have a hard time meeting someone they want to settle down with. The possibilities make them less risk adverse.

Here is the research from Science Daily News. I have yellow highlighted the interesting sections.

Summary:
Evolutionary researchers have determined that settling for 'Mr. Okay' is a better evolutionary strategy than waiting for 'Mr. Perfect.' When studying the evolution of risk aversion using a computational model of digital organisms, researchers found that it is in our nature -- traced back to the earliest humans -- to take the safe bet when stakes are high, such as whether or not we will mate.
How risk averse we are correlates to the size of the group in which we were raised. If reared in a small group -- fewer than 150 people -- we tend to be much more risk averse than those who were part of a larger community.
It turns out that primitive humans lived in smaller groups, about 150 individuals. Because resources tend to be more scarce in smaller communities, this environment helps promote risk aversion.

When studying the evolution of risk aversion, Michigan State University researchers found that it is in our nature -- traced back to the earliest humans -- to take the safe bet when stakes are high, such as whether or not we will mate.
"Primitive humans were likely forced to bet on whether or not they could find a better mate," said Chris Adami, MSU professor of microbiology and molecular genetics and co-author of the paper.
"They could either choose to mate with the first, potentially inferior, companion and risk inferior offspring, or they could wait for Mr. or Ms. Perfect to come around," he said. "If they chose to wait, they risk never mating."
Adami and his co-author Arend Hintze, MSU research associate, used a computational model to trace risk-taking behaviors through thousands of generations of evolution with digital organisms. These organisms were programmed to make bets in high-payoff gambles, which reflect the life-altering decisions that natural organisms must make, as for example choosing a mate.
"An individual might hold out to find the perfect mate but run the risk of coming up empty and leaving no progeny," Adami said. "Settling early for the sure bet gives you an evolutionary advantage, if living in a small group."
Adami and his team tested many variables that influence risk-taking behavior and concluded that certain conditions influence our decision-making process. The decision must be a rare, once-in-a-lifetime event and also have a high payoff for the individual's future -- such as the odds of producing offspring.
How risk averse we are correlates to the size of the group in which we were raised. If reared in a small group -- fewer than 150 people -- we tend to be much more risk averse than those who were part of a larger community.
It turns out that primitive humans lived in smaller groups, about 150 individuals. Because resources tend to be more scarce in smaller communities, this environment helps promote risk aversion.
"We found that it is really the group size, not the total population size, which matters in the evolution of risk aversion," Hintze said.
However, not everyone develops the same level of aversion to risk. The study also found that evolution doesn't prefer one single, optimal way of dealing with risk, but instead allows for a range of less, and sometimes more-risky, behaviors to evolve.
"We do not all evolve to be the same," Adami said. "Evolution creates a diversity in our acceptance of risk, so you see some people who are more likely to take bigger risks than others. We see the same phenomenon in our simulations."
