生命兴亡皆有寿限,万物生灭必有穷期。凡是生物都有一定的生存年限,通称寿命,也叫寿限。寿命长短是由什么决定的呢?经过科学家的多年探索。发现一切生物的寿命都是由遗传基因决定的。可是遗传基因是怎样制约着寿命的,除此之外还有哪些因素影响着寿命呢?近年来在这些方面又有了一些新的发现。寿命研究新成果将会对人类长寿有所裨益。
Life and death are all lifespan, there must be a lifetime of all things. All living creatures have a certain life span, commonly known as life expectancy, also known as life. What is the life span of the decision? After years of exploration by scientists. Discovering the life span of all living things is genetically determined. However, how genetic factors constrain life expectancy, and what other factors influence life expectancy? In recent years there have been some new discoveries in these areas. The new results of life research will benefit human longevity.
