" On July 1, 1858, a letter from Lyell was read before the society: “These gentlemen, having, independently and unknown to one another, conceived the same very ingenious theory to account for the appearance and perpetuation of varieties and of specific forms on our planet, may both fairly claim the merit of being original thinkers in this important line of inquiry.” Lyell then shone the spotlight on his friend: an abstract of an essay Darwin had written in 1844 was read first, followed by a summary of a letter Darwin had sent to the American botanist Asa Gray in 1857. Wallace’s paper was read last, almost as an afterthought. "
