colorful faces of monkeys

為何靈長類是眾多哺乳動物中,擁有最多不同顏色的皮膚和毛髮?原來群居靈長類會以面孔分辨自己的種族,而群族愈大面部圖案亦較複雜。相對喜歡獨居或生活圈細小的靈長類,圖案就沒有那麼豐富了。

why does primates have rich and colorful facial patterns unlike the other mammals? that is because they would identify their own ethnic group with their faces. the larger the group is, the more complicated facial pattern their members would have. those solitary or small group primates would have simpler facial patterns.

Color patterns of monkey faces reflect social order
