Does anyone remember that Star Trek: TNG episode where they're piecing together a message left in the DNA of different worlds and it makes a message from the First Race? And apparently the story was that the First Race found themselves to be all alone in the Milky Way galaxy, and so put the seeds of life and sentient life on a whole bunch of planets? Well I do.
The reason I'm bringing this up is because here's a picture of them: http://www.utfp.org/HQ/Library/xenobiology/alphaquadrant6.html
Now tell me, don't they look a lot like The Founders? Considering that The Founders admitted to having been solids once, and evolved into shapeshifters, I think The Founders and The First Race are THE SAME SPECIES! Or at least, The Founders evolved directly from The First Race.
OH MY GAWD!!!
