OK, I'll make it easier still... You can start with any microorganism.. Or you can genetically engineer one to your specifications... You're just dodging... You can't face up to the absurdity of what you believe.<quoted text>
Giraffes did not evolve from E. coli.
You ideas, born of ignorance of the science of evolution, have been debunked. If you have no better than a straw-man idea of what evolution is then it is not reasonable to try to teach you anything above the basics.
Remember, selective breading uses some of the mechanisms of evolution, but is not evolution in that it restricts diversity rather than expand it as evolution does.
This is a very simple Bio 101 concept. Why are you having such trouble with it?
And tell me ... If evolution can take any one of infinite numbers of pathways as you claim, what's preventing the selective breeding of human from a banana? We do share 60% genetic homology already... You're the one who doesn't understand evolution.
