‘You Are Not The Father’: Dads Who Unknowingly Raise Non-Biological Kids Are Actually Rare

Well, it turns out the sound of an actual ticking clock can speed up your reproductive timing, making you want to have babies earlier, according to a new study published in Springer ‘s journal Human Nature. Researchers asked men and women questions about their reproductive attitudes—things like when they’d like to marry and have kids and how much they’d be willing to alter their “requirements” for a mate in order to start a family earlier—and they found that the sound of a ticking clock influenced women’s answers, possibly because it made them think about the passage of time.

Women who grew up in lower socioeconomic areas were particularly affected, wanting to get married and start families even earlier—and placing a lower priority on their mate’s status and earning potential—than women who were raised with more resources. Not surprisingly, men, who can typically father children well into their later years, were not affected by the clock sound.

As Jesse Singal notes in New York , “all sorts of subtle cues can affect how people answer questions,” but this result is still “kinda weird.

This intimate panel discussion will focus on the biological clock and its impact on sex, dating and personal relationships. Topics will include the latest advances in assisted reproductive technology and fertility preservation, fertility basics and myths, the challenges associated with trying to.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter. Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection. A graph of the average fitness of a population in relation to the frequencies of genotypes in it.

Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. Also called a fitness surface. A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations. If such a behavior is even partly genetically determined, it will tend to become widespread in the population. Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited — unless it becomes positively disadvantageous in the new environment.

The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches for example, Darwin’s finches. The term can also be applied to larger groups of organisms, as in “the adaptive radiation of mammals. A mode of coping with competition or environmental conditions on an evolutionary time scale. Species adapt when succeeding generations emphasize beneficial characteristics.
