Anthropmorphics is a really good expansion from Eric Gans' originary hypothesis, furthering the study of generative anthropology. If it's even partially correct then it necessitates the complete reforming of all the secular disciplines from a mimetic perspective.
It covers many topics that gans had little to say about and branches off from gans in many other topics from the development of language, to the origin of social hierarchy and power, to how the economy and government should be organized around a social center. It attacks a lot of the secular liberal thought at its core assumptions and provides a more cohesive alternative. Through the lens of mimetic theory he finds interesting paradoxes and inconsistencies in tons of mainstream ideas. He describes how the assumption of moral equality necessitates totalitarianism because pure equality cant exist without being enforced and micromanaged totally. He points out that the act of critiquing power misuse assumes that infallible power is possible. He even finds Hayek's knowledge problem to be a non sequitur and provides an interesting alternative, placing libertarian economics on shaky ground. He has a good critique of democracy, saying that it's insanely complex and ineffective at its task of transferring power. It's riddled with problems like "who determines the validity of the election? They then have sovereignty rather than the voters" or "why can't mature 17 year olds vote but immature 18 year olds can? Why can't foreigners vote since the election result impacts them? This discrimination invalidates the spirit of the process". He refutes lots of secular social studies in one sentence by saying, "the project turned out to be impossible because the "human" individual must be taken as its own origin". If you found gans interesting this is definitely the next step. He continues the trajectory of gans' efforts and develops the ideas into applicable political and philosophical principles.
However, I think it must be stressed that the biggest significance of generative anthropology isn't in its innovations in the social sciences. Rather, the significance of GA is that it reverse engineers God out of human behaviors. It affirms the existence of God by pointing out the centralized origins of humanity. And it does this using a secular method which can appeal to atheists. The scientific innovations that GA provides then serve to compliment a strong theology and allow us to place our socio-political ideas, philosophical ideas, and our own behaviors in their proper relation to God, the ultimate sacred and divine center, rather than around some nihilistic assumption that human behavior just originates out of its evolutionary usefulness.
