Mammalia summary

colours are beautiful, or are conspicuously & variously curiously arranged, without being of the least service as a protection, & especially when they are associated with various apparently various ornamental appendages of hair, we are partly led by analogy to the same same conclusion except that though in this case the colours in regard to the & ornaments have been transmitted from the males equally these acquirement through sexual selection primarily by the males, but with subsequent equally transmission to both sexes. That sexual difference of colour, & even highly conspicuous or colours diversified colours in both sexes, are commonly associated as the with as a general rule in the same group or sub-group with other secondary sexual characters either for war or ornament in very plain, when the consider may be observed if we run look through the various cases connectedgiven in this chapter. The law of the equal transmission of exactly acquired characters first acquired through sexual selection, as far as colour & other ornaments are concerned, has prevailed far more more more extensively with mammals than with birds; but weapons in regard to weapons, namely horns & tusks, whether canines or incisors, there have often been transmitted in a much more developed condition
