What your saying is that because of our downgrading DNA and the fact that our DNA doesn't "evolve" or grow with us, means that Earth was seeded by
The conventional theory is humans evolved here naturally and that with our natural evolution our DNA must have evolved as well.
(Not saying I agree or disagree just trying to understand is all)
Consider the Survival of the Most Beautiful Theory, also known loosely as anagenesis
versa). [slight mockery of concept]
Imagine that we're living 30,000 years ago. Our brain size is only about 900cc. There are only a few hundred thousand of us living in all of lower
Europe/ Middle East/ Asia. Others are still in Africa. Others still are just apes.
So your great grandfather was a strong man. That's why your selective great grandmother chose to have his baby. Your grandmother was then both strong
and smart enough to pick a healthy mate. She stayed with your grandfather who was similarly raised, exhibited smoother, less hairy skin and the skill
to construct nice wooden huts. They produced a rather upright-walking Father of yours. And your Mother was similarly raised.
You then frolicked around ogling hairy girls, but you find only the less hairy, smaller-jaw girls attractive. Same for the girls checking out the
furry guys. Eventually two of you big brainers end up producing children who are noticeably less hairy, stronger, smarter, more skillful, social,
communicative, and better looking than other kids. And they only hang out with similar kids. And so on and so forth.
All while mutations that cause larger brains with higher intelligence explains all this, the process may actually have occurred over many thousands of
So at some point around 20,000-25,000 years ago, you become the Homo Sapien species proper (as opposed to Homo Erectus or Homo Rhodesiensis or one of
the others). You're completely different from those Neanderthals. You thrive and successfully survive in competitively outbreeding them. This is
evolution. Eventually you discover irrigation and farming, establishing civilizations in the Mesopotamia region, build vast empires, etc.
But you maintain all your physiological and cranial/ intellectual attributes UNCHANGED for another one thousand generations (roughly 20,000 years) to
today? How is that possible?
Because if you're the genetic type that naturally selects your mate based on not just physical beauty such as a smoother cranium (as opposed to a
Neanderthal cranium), but also on traits like strength, health, skills, sociability, intelligence, etc.,
Why wouldn't all humans today have by now genius level intelligence, look completely hairless, have gargantuan brains, utterly smooth skin, beautiful
body proportions, etc.?
Why suddenly stop evolving 20,000 years ago?
And if this simply disproves the Anagenesis theory, then what evidence do we have for the opposing Sudden Appearance of Big Brain Theory (also known
loosely as Cladogenesis
). What evidence do we have of a global environmental change affecting
Homo Erectus or Homo Rhodesiensis or similar) 25,000 years ago in Africa? What caused the mutation to suddenly produce a clean Homo Sapien?
I'm not claiming to be an expert in any of this, but you can't have it both ways.
