在这里，我调查，整理和合成对比色在5000种陆生哺乳动物集中在黑色和白色皮毛。在简要回顾了哺乳动物着色的替代功能假说后，我检查了9种颜色模式和组合，对身体的不同区域，并为每个哺乳动物分类群，试图确定最有可能的进化驱动力的对比着色。警戒和同种信号是最一致的解释黑色和白色皮毛的哺乳动物;背景匹配可能解释白色皮毛。对比色的证据是通过模式混合，破坏性着色或其他功能，如信号优势，诱惑，减少眼睛眩光或温度调节参与隐藏，几乎没有超越轶事阶段的调查。性二色性在该分类群中受到限制，其基础尚不清楚。令人惊讶的是，在150年前科学界刚刚发现的大多数大型魅力黑色和白色哺乳动物中，皮毛颜色的功能意义仍然是一个谜。
Here I survey, collate and synthesize contrasting coloration in 5000 species of terrestrial mammals focusing on black and white pelage. After briefly reviewing alternative functional hypotheses for coloration in mammals, I examine nine colour patterns and combinations on different areas of the body and for each mammalian taxon to try to identify the most likely evolutionary drivers of contrasting coloration. Aposematism and perhaps conspecific signalling are the most consistent explanations for black and white pelage in mammals; background matching may explain white pelage. Evidence for contrasting coloration is being involved in crypsis through pattern blending, disruptive coloration or serving other functions, such as signalling dominance, lures, reducing eye glare or in temperature regulation has barely moved beyond anecdotal stages of investigation. Sexual dichromatism is limited in this taxon and its basis is unclear. Astonishingly, the functional significance of pelage coloration in most large charismatic black and white mammals that were new to science 150 years ago still remains a mystery.
