That's wild-eyed speculation. One could just as easily say that however automobiles got started, they started over a century ago and they have evolved quite a bit, but one would be completely wrong. The cars didn't evolve; their Designers changed them.
Likewise, the code re-use of DNA strongly suggests that life forms don't evolve into other life forms, but rather that the Designers of life forms (especially notable with artificial computer life and computer software viri) created new versions.
To disregard the precise mathematical code reuse of Base-4 DNA and speculate that species randomly morph into other species is hardly rooted in ANY proven scientific evidence or basis.
You're ignoring that we have objective evidence for DNA changing by mutation.
How many times did "the designer" step in here?
