...This is because all living things are originally created by multiplying a single cell, and as long as there is not much difference in the metabolic rate of the cells, it takes a longer time to create a larger body. Sacher (1917-1982) found a correlation by comparing the weight and lifespan of about 60 types of mammals. The larger the body, the smaller the body surface area compared to weight, so less heat is dissipated, less heat is generated by metabolism to maintain body temperature, and the number of breaths per unit time is reduced, resulting in less physical wastage. *Some of the terminology referenced in "Sacher, GA" are listed below.

…これはどの生物も,もとは1個の細胞から増殖してつくられるので,細胞の物質代謝速度にそれほど差がないかぎり,大きな体のものほどつくるのに長い時間を必要とするからだろう。ザッハーG.A.Sacher(1917‐82)は約60種類の哺乳類の体重と寿命とを比較して相関関係を見つけた。体が大きいほど,体重に比べて体表面積が小さいので熱の発散が少なく,体温を維持するための代謝による発熱が少なくてすみ,単位時間当りの呼吸回数も少なくて体の消耗が小さいというのである。… ※「Sacher,G.A.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
