Regarding genetic manipulation, and the "fallen"; and wanting to "strengthen" the gene pool. Does it remind you of Hitler at all?
Who do you think influenced Hitler? Breeding for genetic traits was not his original idea.
As you can see from this story, it was something taught to Jacob by these alien/angels.
It is evident by his knowledge of animal husbandry which is described in the scriptures, and by his sly way of using it for a personal agenda, that this was a secret knowledge.
And how was he priveliged to learn the secrets of breeding solid white animals vs spotted animals? How did he know which would be the stronger breed when he made a bargain with his father-in-law?
Jacob understood genetics because this knowledge was taught to him as part of the agreement with the alien.
'Wrestling' with the angel meant negotiations, not a physical tangle.
Jacob made an agreement to allow them to use him for their genetic experiments on his lineage, and in return he was given knowledge.
When Jacob was able to use that knowledge of breeding with the animals, it was manifested proof to him that his lineage would be a superior group of people.
Have you been this analytical your whole life?
Like most people, I started the "Why" stage as soon as I could talk. The difference is that I never stopped asking.
Also, in studying English literature I had a fantastic teacher by the name of Ramses.
Have you been dissecting the wall, the flower, or both?
Flower in the crannied wall,
I pluck you out of the crannies.
I hold you here, root and all, in my hand.
Little flower--but if I could understand
What you are, root and all, and all in all,
I should know what God and man is.
