But transitional forms are also the rarest of beasts.
不過(guò)過(guò)渡型物種也是最罕見(jiàn)的動(dòng)物
By their very nature they were few in number and lived for just a short intermediate time until a wholly new animal evolved.
從它們的性質(zhì)不難看出，它們不僅數(shù)量少，而且只生活在非常短暫的過(guò)渡時(shí)期，直到進(jìn)化成全新的物種
In fact for years there was only one accepted transitional form - the archaeopteryx
事實(shí)上，多年來(lái)只有一種認(rèn)可的過(guò)渡型物種--始祖鳥
which was a dinosaur with feathers that marked the transition to birds.
一只長(zhǎng)羽毛的恐龍，標(biāo)志著向鳥類的過(guò)渡
Presumably the transitional forms are very rapidly outcompeted by their more, by their own more advanced descendants
大概是因?yàn)檫^(guò)渡型物種很快即被它們自己更先進(jìn)的后代所取代
so these transitional episodes in the history of life tend to be brief
使得這些生命歷史中的“過(guò)渡插曲”相當(dāng)短暫
and involve, it seems, relatively low numbers of species and probably low numbers of individuals.
包括這些動(dòng)物的物種數(shù)量可能比較少，種內(nèi)數(shù)量也可能非常少
The trouble was without anything half fish/half tetrapod between eusthenopteron and ichthyostega
問(wèn)題是，真掌鰭魚和魚石螈之間若是找不到半魚半四足類的動(dòng)物
the story of how we got our legs remained incomplete and lurking out there
那么關(guān)于我們?nèi)绾伍L(zhǎng)出腿的故事就會(huì)變得很不完整
was a group dedicated to pointing out such gaps in the story of evolution with the aim of its ultimate destruction.
那兒總有一些人，一心想要找出進(jìn)化理論中的這類破綻，直到它最后整個(gè)坍塌。
