They are observed as evolution. Have you ever heard of endogenous retroviruses?

I fail to see how an epigenetic causal agent such as lead disproves evolution. Your argument isn't persuasive at all.

There is no proof that evolutionairy changes aren't epigenetic.

Negative proof. Additionally, epigenetic theory rests on both environmental AND heredity.

It doesn't matter the only difference between it being epigenetic or not is the time at which the force strikes. There is no rule that says forces can't attack prior.

Which forces?

A mutation, in order to be passed genetically to the next generation no matter its origin, must be present in the sex cells. If something is present in, say, the liver cells, it's not getting passed on.

Do you understand what I'm saying here?

Intorducing lead into ones system is enviromental. Once it changes the genes, it can then also be passed on as well.

Sounds like your only referring to sexuall speciation.
