Abstract

The relationship between size and lifespan is complex. Larger species normally outlive smaller species, but within species smaller individuals generally outlive larger individuals. Research comparing size and mortality in dogs suggests that big dogs die young because they age faster.

摘要

大小和寿命之间的关系很复杂。一般来说，体型较大的物种比体型较小的物种寿命更长，但在同一物种中，较小的个体通常比较大的个体寿命更长。对狗的大小和死亡率进行比较的研究表明，大型犬死得早是因为它们衰老得更快。
