"more speedy development of the spirit complex"

[Parsons]

Very interesting catch. I have some pertinent info to add to your discovery from the same session:

18.15
QUESTIONER: Can you tell me what these genetic changes were and how they were brought about?

RA: I am Ra. Some of these genetic changes were in a form similar to what you call the cloning process. Thus, entities incarnated in the image of the Yahweh entities. The second was a contact of the nature you know as sexual, changing the mind/body/spirit complex through the natural means of the patterns of reproduction devised by the intelligent energy of your physical complex.

So, the SMC Yahweh cloned the 3rd density version of themselves, incarnated into those vehicles, then bred with the native population. So to put that together with your understanding, Plenum, we are genetically part Yahweh, part Martian, and (presumably) part late-2D Earth hominid.

I can't believe I never caught this.

EDIT: I missed it initially, but it appears we are also part Anak:

18.20
QUESTIONER: When did Yahweh act to perform the genetic changes that Yahweh performed?

RA: I am Ra. The Yahweh group worked with those of the planet you call Mars seven five, seventy-five thousand [75,000] years ago in what you would call the cloning process. There are differences, but they lie in the future of your time/space continuum and we cannot break the free will Law of Confusion.

The two six oh oh [2,600], approximately, time was the second time— we correct ourselves— three six oh oh [3,600], approximately, the time of attempts by those of the Orion group during this cultural complex; this was a series of encounters in which the ones called Anak were impregnated with the new genetic coding by your physical complex means so that the organisms would be larger and stronger.
