Why Women Now Faster Puberty?

Women in this age experiencing puberty much earlier than ever before . In the United States for example , according to one recent study, more than 10 percent of women in that country has been experiencing growth in the chest at the age of 7 years .

 

According to research published " Psychological Science" , Association for Psychological Science journal , the woman who physically mature earlier, showed a tendency to go out early, having sexual intercourse at a younger age , and have more sex partners than women in the era.

Therefore, the possibility of them contracting sexually transmitted diseases are very high , so the possibility of giving birth in their teens .

Jay Belsky of Birkbeck University in London, The UK , this judge may be bad news for some people, but he actually saw fenomema was natural and reasonable from the perspective of biological evolution .

This leads to the hope that humans sekaranga grew up in risk and unstable environments , has accelerated the maturation ( puberty ), thus increasing the likelihood of someone before they reproduce dead.

To examine the relationship between risk , unstable environment as reflected in the bond of mother and baby are not safe (less affection ) , and early puberty , Belsky and colleagues used data 373 white women .

The data are drawn from research on early development of children who supported the National Institute of Child Health and Human Development .

Women investigated, monitored from birth until the age of 15 years . At age 15 months , security ties with the mother's children were evaluated using standard procedures involving weaning and infant reunion with her mother in a single laboratory.

The baby is smiling , silent , holding hands , or vice versa showed positive reactions when their mothers return is considered safe , otherwise they are to avoid the mother during weaning or not comforted by the return of the mother , the babies of women was not considered safe .

pubertal development was evaluated by a physical test every year by a nurse or doctor since the 9.5 -year -old woman .

However, the risk and start a volatile environment as reflected in the fragile family ties , is not the only reason why women mature faster . That's partly because there are genetic factors .

In addition, chemical factors may also be influential , as well as nutritional improvements are considered to be the trigger of the last 150 years the trend that causes rapidly mature women .

The results found that women are not safe (less affection ) when a baby has developed puberty earlier than children his age , approximately two to four months faster than women during the baby safe.

The girls also end development in puberty and menstruate earlier than women who are safe as a baby .

Belsky said , was raised and the environment in which the baby - mother attachment relationship is very influential and should not be ignored.

 

" From the perspective of evolutionary biology that shows the things that nature cares about is the spread of most genes to later generations , " Belsky said as quoted by ScienceDaily .

He revealed the phenomenon is convinced that human beings become more easily bred since adolescence or early puberty becomes more so that people can get married early.
