Biologists have long maintained that two groups of
pinnipeds,sea lions and walruses,are descended from
a terrestrial bearlike animal,whereas the remaining
group,seals,shares an ancestor with weasels.

生物学家长期认为两组鳍足类动物(海狮和海象)是陆生的熊类动物的后裔,但是剩下的一组(海豹)和鼬鼠共有一个祖先.1 share 2 with 3的意思是 1和3 分享2, 或共有2. 不能译为“他们同一个祖先是黄鼠狼----they share an ancestor that is weasels.”
