Genealogical Relationships Do Not Support Indirect Speciesism

In this article, I will identify an argument for the conclusion that all human moral agents have stronger moral reasons regarding other human beings than they do regarding nonhuman animals, and I will explain why I think this argument is unsound. The argument employs an empirical claim, that all human beings are more closely genealogically related to all other humans than they are to any nonhuman animals, and a moral claim, that one's genealogical relationship to an individual is a morally relevant consideration. The moral claim is supported by a comparison between genealogically related individuals and a family.
