根据研究发现, 日本的卵产卵量较大的人寿命缩短了20%. Japanese quails laying larger eggs live 20% shorter lives, study finds.

对于日本的, 一项新的研究表明:如果投入更多精力在繁殖上, 比如产出更大的蛋, 就会加速衰老. A new study on Japanese quails suggests that investing more energy into reproduction, such as laying larger eggs, accelerates aging. 研究人员发现, 选择性繁殖以产卵量较大的雌性平均寿命为595天, 比小蛋的母体少约20%. Researchers found that females selectively bred to lay larger eggs lived an average of 595 days, about 20% less than those bred to lay smaller eggs. 这项研究支持进化论, 认为高生殖力会损害长寿和免疫功能. The study supports evolutionary theories that high reproductive effort comes at a cost to longevity and immune function.
