already having many irreversible effects climate change, according to the statements of scientists, newborn babies gender will also affect it. The research, which was carried out according to data from many different places, also reveals how the male and female genes are affected by the environment.
in Japan, in the aforementioned research, scientists, especially boys, to external factors that will put stress
against suggested that it was more vulnerable. Scientists examining the earthquakes in Japan and the birth data of those years supported this with the data they obtained.
In babies born 9 months after the earthquakes, the rate of baby boys decreased by 6 to 14 percent compared to the previous year:
Scientists, who included more than one earthquake in the research, found that babies born at the end of 9 months following these earthquakes compared to the previous year. that the proportion of men has decreased between 6 and 14 percent. said.
Although scientists do not yet know why the sex ratio is so affected, the lead author of the study Dr. Misao Fukuda, found in males The fact that the Y gene is more vulnerable to stress stated that it may have something to do with the issue.
Is the number of baby girls who lost their lives more than boys?
He said that the sex ratio was equal at first, but changed greatly during pregnancy. Steven Orzack, states that in his research, they have seen that girls die more than boys during pregnancy.
from the University of California Ray Catalano draws attention to natural selection. Catalano stated that the mother was biologically and constantly defended against some sperms, but allowed some of them to pass. that chromosomal and genetic features play a decisive role. states.
around the world every 103 to 106 boys were born for 100 newborn girls. said Catalano, wherever they have data baby boys prenatal to die states that they are more prone. In addition, although the reason is not clear, male infants biologically says she is weaker, less vulnerable to diseases and prenatal death.
Colder years mean fewer boys:
Information covering the years between 1878 and 1914, presented by Catalano by examining the northern countries, there are fewer boys as a result of cold years, but this is what is seen more durable than others
It turned out to be . It was also seen that these children who grew up from here gave birth to more children than expected. This supports Catalano’s idea of natural selection.
Stating that a new and rapid adaptation process will come with global warming, Catalano said that such situations less predictable it says it will. Again, with global warming, drought
Stating that problems such as will also contribute to stress, Catalano finally concludes his statements by saying that as the climate changes, the characteristics of the population will also change.
Warmer years mean more boys:
from Turku University Samuli Helle, in his study, every 1 degree Celsius in the positive direction being a man probability of 0.06 percent
with a ratio like raised revealed. This means that an annual increase of 3 degrees will cause 0.18 percent more male babies to be seen.
This ratio may seem small to you. It already is. But Helle is quite crowded places annually when we think about it up to a few thousand extra boys says it can be seen.
While scientists are discussing whether the said effects are permanent, it is said that these effects will not affect the whole world. This issue, which we can say that we are progressing with theories that sound quite logical at the moment, will be resolved in time.
