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。
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。
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。
