Father sad destroy, because their daughter at the time of ovulation to myself sardonically. In 2011, the latest evolutionary psychology published in the top journals in psychology "Psychological Science".
[Stories from women's ovulation period talk]
With other animals, the human female no obvious estrus. But they have relatively hidden ovulation, the highest probability of pregnancy in this period. Evolutionary psychologists believe that women who have full use of the information asymmetry advantage concealed ovulation through the platform, trying to better achieve their evolutionary interests. Compared to other phases of the menstrual cycle, ovulation period exhibits excellent characteristics for men strong preference. Whether it is full of magnetism deep voice, masculine or valiant face, so that they are elated, unable to stop.
Ovulation susceptibility, also means that compared to other phases of the menstrual cycle, women at this stage to bear the same risks as more serious consequences. Therefore, they have reason to be more vigilant to keep possible risks attitude, this risk including incest. Incest offspring species can cause genetic degradation, they are more likely to have a genetic disease and infected with various diseases, so most will die young. Incest consequences greater impact on female animals, they usually have a possible incest exhibit higher vigilance. Reports from the animal kingdom it clear that in estrus female voles, mice and cats, are trying to hide their male relatives.
In 1996, the French zoologist Monod (A.-M. Monard), Duncan (P. Duncan) and Boyd (V. Boy) published a study them more than a decade. By 40 he observed a young mare, Monod, who found the young mare estrus vulnerable to sexual harassment of male relatives, and even then they only stallion with other groups from mating. Older mares also helped to drive Bushihaodai also ill stallion relatives. But what makes the older mares was pleased that natural selection has been designed to protect his daughter's good ideas, all young mares are in estrus comes the initiative to leave the original family, the vast majority of them are He joined the new horses, the other young mare with strange single stallion similar composition Roma families homeless. Monod, who believe that the young mare in estrus, "away from home", in order to avoid incest with his male relatives occur.
[Female ovulation rejection of his father more]
The question arises: whether the woman will be like a cat, as in the time of ovulation exclude men of your own home it?
From the University of Miami Li Boman (D. Lieberman), California State University, Pierce Worth (EG Pillsworth) and the University of California, Los Angeles Hasse Hamilton (MG Haselton) for the first time on this issue were investigated. They recruited 48 female UCLA student, detailed investigation over the past month their phone call records, recording the frequency and duration of them with his mother and father call.
The result is very interesting. In terms of a call, frequency and duration of the non-ovulation women every day to call his mother with his father about the former is 0.6 times three minutes, which is 0.5 times 2.2 minutes. But in the time of ovulation, these female students apparent in his father's indifference and rejection, they call to his mother every day 0.8 times 3.6 minutes, and left his father's quota is 0.2 times a day, every 1 minute .
Phone connection, even if there is no right to decide how many women still can choose the length of time to answer. In this case, whether or not they will not give his father "national treatment" mean? The answer is yes. Whether in peacetime or during ovulation, female students answered the mother calls the length of time does not change. When, however, compared to the usual, they receive a phone call from his father in earlier ovulation will tell him to say "goodbye."
[Evolutionary psychology explanation fly it? ]
It looks like things are clear. Women do in their time of ovulation would his father a new light, to spend less time talking with them.
Scientific research, in order to better explain their hypothesis is correct, it is best to find an alternative hypothesis, then prove that this alternative hypothesis out of touch. Li Boman et al found such a target: perhaps the daughter of his father's cold because they spend more time to communicate with his mother, at the time of ovulation because they may be more willing to discuss the topic mate with the mother, and therefore leaving poor father very little time. If this assumption is correct, then the female ovulation father's rejection of perhaps just "not enough time" results, they assume that evolutionary psychology is to avoid a possible incest views object is not so firmly up.
This alternative hypothesis it is a bit like the truth. However, Li Boman, who believe that this assumption is untenable. According to this hypothesis, the mother's phone call more times the number of phone calls to his father should be the the longer the time to call his mother, his father call time should be shorter. Unfortunately, the actual situation on the contrary. In addition, women ovulation more intimate relationship with her mother, will spend more time talking to his mother. However, regardless of whether the relationship with his father usually close, they will reduce the contact time with his father.
So, against the theory of evolution to explain the target was knocked out. However, evidence of ovulation of female relatives of heterosexual exclusion still needs to be strengthened. Perhaps one day, other studies have also indicated that, in addition to his father, ovulation period will also reduce the contact with other male relatives (both uncle, uncle, brother or brother), but not with the exclusive approach their sex relatives (aunt, aunt, sister, sister). Regardless of whether this study Li Boman, who presented may indeed mean that women like ovulation estrus cat, as will naturally reduce the contact with his father. Special period, special treatment. - When the father will not complain, understanding long live.
