The main condition of long life is defined


Specialists of the biotechnological company Calico Life Sciences and the genealogical company Ancestry have found out that genes to a lesser extent define life expectancy, than was considered earlier. Major factors of longevity are influence of the environment and a way of life. It is reported in the press release on MedicalXpress. According to the previous estimates, the longevity is defined on 15-30 percent by genetic distinctions, and other factors are the way of life, influence of society, a disease and accidents. In new work scientists have considered family trees more than 400 million people. At the same time researchers considered only time of life of each specific person, the place of his birth and family relations. Scientists have carried out the statistical analysis of factors of longevity at relatives who were born in XIX and the beginning of the 20th century, and have estimated heritability of life expectancy at the family and cousins and sisters. It has turned out that the correlation between spouses was higher, than between blood brothers and sisters that indicated that the major role is played by environment factors. Identical conditions of the environment or a positive assortativnost when people choose the partners leading a similar life can be such factors. Taking into account results researchers have come to a conclusion that the heritability is defined by genes only on seven percent. It is more than important news in Film of Day Telegram-channel.
