The tuatara rate is significantly faster than for animals including the cave bear, lion, ox and horse.
刺背鳄蜥的进化速率比起包括洞熊、狮子、公牛和马在内的动物，都要快得多。
Tuatara once ranged throughout New Zealand before rats, cats, and stoats— introduced by human colonizers— wiped them out.
据殖民者们介绍说，大蜥蜴以前遍布新西兰，直到老鼠、猫和白鼬把它们挤掉。

Saving the tuatara is a matter of pride among new zealand's indigenous groups. the animals are revered by the maori as a taonga or treasure.
拯救大蜥蜴在新西兰土著部落里是一件荣耀的事情。这种动物被毛利人视宝贵财富。
Of course we would have expected that the tuatara, which does everything slowly — they grow slowly, reproduce slowly and have a very slow metabolism — would have evolved slowly.
我们本以为刺背鳄蜥应该进化得很慢，就像它们做什么事都很慢一样——长得慢，繁殖慢，新陈代谢也慢。
However, while a boost in temperature generally results in a nest full of more females than males, the opposite is true for tuatara whose offspring skew toward male in warmer climes.
通常来说，如果温度升高，雌性后代的出生率就会高一些。但鳄蜥的情况正相反，在更温暖的环境下，雄性后代的出生率更高。
Among the several subclasses (or "orders" in biology) of reptiles are snakes and lizards, turtles and tortoises, crocodiles and alligators, and the tuatara, a marine lizard in New Zealand.
在几个亚纲（或生物学的“目”）的爬虫类中，有蛇和蜥蜴、乌龟和陆龟、鳄鱼和短吻鳄以及虫蜥蜴——一种现存于新西兰的海蜥蜴。

They found that, although tuatara have remained largely physically unchanged over very long periods of evolution, they are evolving - at a DNA level - faster than any other animal yet examined.
他们发现，虽然刺背鳄蜥的大部分形态在长期的进化中并没有产生变化，但从DNA层面上看，它们比其他已经检测过的动物的进化速度都要快。
