家鸡的寿命一般是20年左右,但在现实生活中,家鸡养到1至2年就会被“请”上餐桌,所以我常想,长此以往,许多年后,家鸡的寿命也会缩短为1至2岁。我是这样论证的:姑且假设家鸡寿命基因中有一个寿命基因A,A专门控制并促使家鸡在20岁左右衰老死去。可是,A的密码被设定为在15岁左右时 The life span of a chicken is generally about 20 years, but in real life, the chicken will be “invited” on the table for 1-2 years, so I often think that in the long run, the life span of chickens will be many years later. Reduced to 1 to 2 years old. I argued this way: Let’s suppose that there is a life-span gene A in the chicken life-span gene, and A specifically controls and urges the chicken to die of aging around the age of 20. However, A’s password was set to be around 15
