Before they swam effortlessly underwater, cetaceans evolved from terrestrial  ungulates that slowly adapted to an amphibious lifestyle.

Like, almost all of these extinct South American species had hooves - a feature that's associated  with the living ungulates, like deer and horses.

So  they compared the proteins from the two South American ungulates to those from a range of 76  other mammals from across the mammal family tree.

It can thus obtain food beyond the reach of the other Ungulata or hoofed animals inhabiting the same country; and this must be a great advantage to it during dearths.

因此，可以获得居住在同一国家的其他有动物或有动物无法获得的食物； 这在饥荒期间对来说一定是一个很大的优势。

And, the paleontological evidence, the fossil evidence and evidence from looking at the DNA of living whales and other animals now really strongly points to whales being very closely related to hoofed mammals.

古生物学证据、化石证据以及对现代鲸和其动物DNA的研究结果现在真的有力地指向鲸与有动物的亲缘关系非常接近。

There, animals including snow leopards and mountain ungulates, are being protected by ecotourist projects run by non-governmental organisations, or NGOs - organizations trying to achieve environmental or social aims outside of government control.
