father’s age affects the duration of life of children
This is a sensational discovery made by Russian and British scientists conducted a large-scale study of genetic and statistical data for several centuries.
The scientists conducted a study in which the main purpose was to find out whether there has any effect on the child’s father’s age in which conception occurred. The study results were very surprising, the older man, the greater the risk of increasing mortality among children. After 20 years, every year the risk is increased by about 1%, such shocking data, scientists have come. The data of this sensational study published in the journal PLoS One.
During the study, researchers conducted a detailed study of the data, recorded in the Finnish church books in the period from 1688 to 1899. Scientists believe that it is in this period of time a person can study it from a biological point of view. In the Scandinavian countries, all the dates fixed in detail, not only the birth, marriage and death and birth and the plus in a given period of time in the country was poor and as a result was not normal and full medical care.
Results It was very surprising, 13% more likely to come of age survived precisely those whose not only fathers and grandfathers but procreate up to 30 years, compared with the Finns whose families by the time the child’s father was 40 years old.
Scientists are also reminded that with age in the sex cells not only appear but also accumulate mutations and these mutations are transmitted to children and affect the genetic fitness of offspring.
Also, scientists have found a very interesting fact, it turned out that women whose fathers at the time of their birth exceeded 30 years of age, women are much less likely to marry. However, this fact can not be directly connected with the age of the father may be the relationship with the economic or social aspects.
Study leader George Bazykin, the Institute for Information Transmission Problems. AA Kharkevich Russian Academy of Sciences told about the results of research: “In today’s society is often taken to delay the birth of children to adulthood. In our work with British colleagues for the first time with the involvement of large material shows that the viability of offspring matter what age he became the father of his father, his father – my grandfather, and his grandfather – grandfather. Perhaps, this effect has a genetic nature: fitness decreases due to the accumulation of mutations over several generations ».
Also, scientists are very concerned about the fact that in the semen of men with age accumulates mutations. British scientists have put forward the idea that young men under the age of majority should be frozen sperm and then use that sperm not to transmit genetic mutations.
