哺乳动物的

What they have found makes it likely that many dinosaurs had something rather like feathers, and that those which did not had lost a primitive characteristic of the group in the way that elephants and hippos have lost most of the hair that is characteristic of mammals.

他们的发现表明，可能许多恐龙都有像羽毛的结构。而那些没有这种结构的恐龙，则丢失了原始的种群特征，就像大象和河马那样，丢失了哺乳动物的特征——毛发。

Paleontologists are stunned at the number of species they've dug up, including many previously unknown: A new stegosaur — a tree-grazing sauropod with a nine-meter neck, a new long-toothed pterosaur — a flying reptile, new raptors and even a little mammal-like reptile.

古生物学家对於出土的恐龙种类数量感到惊讶，其中包括许多前所未见的种类：新种剑龙、拥有九公尺长颈，专吃树叶的蜥脚龙、属於会飞爬虫动物，满口长牙的新种翼龙、新种迅猛龙，甚至是状似哺乳动物的小型爬虫动物。

His concern for animals and the environment has taken him to all the world's biogeographic regions, and his scientific work has ranged from the ecology and behaviour of Asiatic elephants to the study of Australian marsupials.

出于对动物和环境的关注，他考察了世界上所有的生物分布区。他的研究工作从亚洲象的生态环境和行为习性到对澳大利亚有袋类哺乳动物的研究，可谓涉猎广泛。

Some studies showed that SPs display toxicity to wildlife and human nervous systems. It may cause acute and chronic neurotoxicity to mammal, and the stereoisomeric structure of SPs affects mammals neurotixicity. There was some enantioselectivity of SPs in acute and chronic neurotoxicity to mammal.

已有研究结果显示拟除虫菊酯类农药对非靶标野生动物和人类的神经系统有一定的毒性作用，其对哺乳动物的神经毒性主要表现为急性和慢性神经毒性，而且其毒性作用与拟除虫菊酯类农药的立体结构相关，有一定的对映体选择性差异。

"Unlike the hair of most mammals, feathers do not cover the entire skin surface of bird s but are arranged in symmetrical tracts alternating with areas of bare skin, which may contain the small, soft feathers called down."

羽与多数哺乳动物的毛不同，并不覆盖于鸟的整个皮肤表面，而是按对称的羽域排列，与裸露的皮肤无羽区相间，后者可能生有小而柔软的羽称绒羽。

Another possibility is that the mammal DNA came from live monkeys or duikers that had been probing the gorilla feces for edible seeds or other leftover plant bits.

另一种可能是哺乳动物的DNA来自活的猴子或羚羊，它们翻动了大猩猩的粪便，想找些可以吃的种子或者没消化干净的植物。

Design of peptide inhibitors for furin based on the C-terminal fragment of histone H1.2The mammalian proprotein convertase furin has been found to play an important role in diverse physiological and pathological events,such as the activation of viral glycoproteins and bacterial exotoxins.

基于组蛋白H1-2片段的furin抑制剂的设计改造在哺乳动物的许多生理和病理活动中，前体加工酶furin起到了非常重要的作用，例如对病毒糖蛋白和细菌毒素的激活。
