Large portions of the genome of these “clearly original” creatures is similar to current day human DNA.

In the book “The Making of the Fittest”, an astounding claim is made: all living things, from the scum living in boiling water of Yellowstone, to plants, to animals, to humans ... share about 500 “immortal” genes in their DNA (primarily used for building cell walls, transcribing DNA to RNA, etc).

If true, the implications are mind boggling.

“If true, the implications are mind boggling.”

I don’t know if it is “mind boggling.”

One could argue evolution-from-common source or creation from-common design using the same evidence.

But it is cool, and should put to rest the “we’re aliens” theory, unless the original alien was a single celled critter.
