Help remembering new Age-y Sci Fi book

[Jrtking73]

I am trying to remember a book I read 20 years ago (or more). I found the book at my uncles house who was a sci-fi geek from the 60's and 70's. By the look of the book and the tone of the book I got a very new age, age of aquarius vibe from it. The plot is that humans have evolved to fit the worlds they live in. On cold planets they have long shaggy fur coats. On hot planets no hair at all. Various sub races have enslaved other sub races and some even use others as food animals. The main Character at the beginning of the book is a woman who is native to the moon. She is small and slight and hairless, part of a technocrat elite who inhabit the moon and are somehow important. She consults with a computer, some sort of AI oracle who tells her she must travel to some distant world and mate with another sub race in the hopes of producing a savior and uniter of all the sub races of humans. That is what I remember. Any help out there? Thanks!

This is definitely the super funky I, Weapon by Charles Runyon (1974).

Here’s a spicy description from a review: “The Future. The Morlocks-- excuse me, the Progs-- live on the Moon and on habitats about Jupiter. Their agents, the Stafi and Landed, do the grunt work and raise the Eloi-- excuse me, the Unguls-- humans so mutated after Terra's first nuclear war that they are fit only as foodstock. Humanity had spread throughout the galaxy, only to be forced back to a few dozen worlds by the villainous Vim. A desperate Prog, consulting The Computer, learns that the only possibility of success is a breeding cycle to create a godlike human who can crush the Vim. The first half of the book deals with her struggles to reach her goal: she has to collect the sperm of an Ungul, an Unchanged, and an "Evolutionary Variant", mix them all together, and then carry the product to term herself all "the old-fashioned way, without the use of a breeding tank or gene equipment," The Computer tells her. The end of the book is an unchallenging narrative of her offspring's heroic success after success.”
