[請益] 環境穩定下生物的演化
演化的力量來自於天擇,
也就是生物對環境的適應性Fitness,
環境變動產生的生存壓力促使生物演化,
但如果環境不變動,
生物還會繼續演化嗎?
所謂的適應性有極限嗎?
生物會不會不斷增加適應性?
即使環境不再提供任何刺激,
仍然不斷創造出越來越高等的生物。
如果有另一個地球,
智人出現是偶然還是必然?

我的意思是,如果地球演化重新來一次,得到智人的機會有多大
如果恐龍滅絕,冰河時期等特殊事件沒有發生,而是維持穩定環境的話。

感謝大家的熱心阿,說到適應極限,人類的頭不再增大,為了不要造成難產,
也是到了智慧的物理限制了。如果智慧出現在恐龍身上,說不定可以比人類還聰明。
