In Life and Letters of Charles Darwin, volume 2, In LIFE AND LETTERS OF CHARLES DARWIN Volume 2, Darwin was writing a letter to his friend about a difficulty regarding "sexual selection":
My difficulty is, why are caterpillars sometimes so beautifully and artistically coloured? Seeing that many are coloured to escape danger, I can hardly attribute their bright colour in other cases to mere physical conditions. Bates says the most gaudy caterpillar he ever saw in Amazonia (of a sphinx) was conspicuous at the distance of yards, from its black and red colours, whilst feeding on large green leaves. If any one objected to male butterflies having been made beautiful by sexual selection, and asked why should they not have been made beautiful as well as their caterpillars, what would you answer?
I think that it means "like", but I found that it is rarely used in such a sense in comparison to using it in the sense of "in addition to", does it really mean "like"? Because I can't understand the contradiction between the objection and the question; he objects to the existence of something, and then asks why shouldn't this very thing exist?
