Indeed the most primitive metazoan (the theoritical common metazoan ancestor) is thought to be incredibly complex genetically, perhaps as much as human beings.
You brought this up in Chiroptera's comb-jelly thread, too. Are you suggesting that the theoretical Metazoan ancestor has the genes for making a liver, heart, feathers, tentacles, tube-feet, gizzard, intestines, claws, antennae, toenails, bones, placenta, amnion, siphon, fins, Malphigian tubules, hair, eyes and/or medulla oblongata, etc.?
I think you're going to have to produce your source for this information.

I will say there is evidence...
Bare assertions don't count for anything. How can I analyze your idea if you won't tell me what you're basing it on? Your hesitance to provide it makes me think you don't actually have it.
randman writes:
...the theoritical common metazoan ncestor likely had genetic sequences associated with complex nerve function and that certainly such sequences exist in invertebrates.
Why do you think this is likely? What evidence do you have that shows such sequences in invertebrates? Why do you have such an aversion to telling us relevant data? I'm going to go out on a limb and says it's because there is no relevant data, and you're just spouting nonsense.

I am not allowed to link it here
What are you talking about? Do you think Percy will boot you for linking a creationist source? Or, is it a copyright issue? If so, who writes scientific papers that they don't want people to link to? Surely your source has at least an abstract in the public domain.

Some people have suggested that the color of the peppered moth is a matter of gene regulation.
Regardless of how the difference came about, the point is that the population changed in response to an environmental factor, and what used to be an adaptive feature became maladaptive, favoring a formerly maladaptive feature.
bertvan writes:
Tell me, do you believe the genes that regulate the expression of other genes also originated by accidental DNA copying errors (random mutation)?
Yes. And, you know what? If a regulating gene were to become mutated, it would change the way the gene it regulates is expressed. This is a known and well-documented phenomenon.
