It also suggests that herbivory evolved in the crocodile clan on several occasions.

该研究还表明鳄鱼家族食草进化了好几次。

What particularly surprised Mr Melstrom and Dr Irmis, though, was the way herbivory mapped onto the crocodile family tree.

让Melstrom和Irmis博士感到特别惊讶是这种食草映射在鳄鱼族谱上方式。

This growth spurt might have initially occurred because some pelycosaurs were adapting to herbivory.

这一生长爆发可能最初是因为一些盘龙类正在适应植食。

And the thing that drove this group to herbivory?

是什么驱使这个群体食草？

Well, there are some real advantages to herbivory.

好吧，草食确实有一些真正优势。

This would mean that the therizinosaurs went from omnivory to herbivory, and were never carnivorous at all!

这意味着镰刀龙从杂食转变为食草，并且根本不是肉食！

The other fauna at Luoping may have also played a part in pushing Atopodentatus toward herbivory.

罗平其他动也可能在推动奇齿龙向草食进化方面发挥了作用。

Or maybe it had other physiological adaptations, like longer intestines for fermentation that helped it get the most out of its food, which is how manatees make herbivory work.

或者它可能有其他生理适应，比如更长肠道用于发酵， 帮助它最大限度利用食，就像海牛那样让草食成为可能。

But, in spite of how well specialized teeth worked for herbivory, plant-eating would actually lead to the loss of teeth in another vertebrate group: the weird mammal relatives known as dicynodonts.

但是，尽管特化牙齿对草食动非常有效，吃植实际上会导致另一类脊椎动——奇特哺乳动亲戚二齿兽——失去牙齿。

What particularly surprised Mr. Melstrom and Dr. Hermes though was the way herbivory mapped onto the crocodile family tree Rather than evolving once at some point long ago and then appearing in all later species on that branch.

特别让梅尔斯特罗姆先生和赫耳墨斯博士感到惊讶是，草食在鳄鱼家族树上分布方式。草食并不是在很久以前某一次进化后就出现在该分支上所有后来种中。
