从达尔文时代到现在，家养动物奇妙的颜色变化一直被认为是进化的一个极好的例证，人们对它是如何发生的问题进行了大量的研究。然而，关于现存的颜色品种是如何起源的，我们几乎没有确切的信息，关于这个问题的理论也存在分歧。因此，仔细记录任何可能阐明这一主题的当代事件就变得非常重要。这是我提请科学家注意最近在英国出现的两种新的、引人注目的颜色变化的理由；普通的或挪威鼠。我特意说“外表”，因为不可能说这些变异在种族中存在了多久，也许只是偶尔偶尔地出现。然而，可以肯定的是，它们只是最近才引起“爱好者”的注意，他们以极大的热情接受了它们。新奇的品种被称为(1)粉红的黄色，淡褐色或奶油色；(2)黑眼睛，黄眼睛，小鹿眼睛，或奶油眼睛。从现有的证据可以清楚地看出，这两种变异都起源于野外
THE marvelous color variation of the domesticated animals has been recognized as a capital illustration of evolution from the time of Darwin to the present, and much study has been devoted to the question of how it has taken place. Nevertheless we have very little positive information as to how existing color varieties originated, and theories differ concerning the matter. It becomes therefore important to record carefully any contemporary events which may throw light on the subject. This is my excuse for calling the attention of scientists to the recent appearance in England of two new and striking color variations; of the common or Norway rat. I say" appearance" advisedly for it is impossible to say how long these variations may have been in existence within the race, cropping out perhaps from time to time sporadically. Certain it is, however, that they have only quite recently come to the attention of" fanciers," who have taken them up with great enthusiasm. The new varieties are known to the fancy as (1) pinkeyed yellow, fawn, or cream; and (2) black-eyed yellow, fawn, or cream. From the evidence at hand it is clear that each of the two variations has originated in the wild 65
