the missing link

Just wanted to know if anybody could site some actual evidence that anything has ever evolved and crossed the genetic lines of species.
Sure, there are variations within species, but if Darwin's theory of evolution is true, as he said in his original book, there should be millions upon millions of transitional forms in the fossil record which shows random mutations happening over hundreds or thousands of generations and leading to the production of a new species.
So far, nothing like this has been discovered in the fossil record. If Darwin's theory is true, and worthy of acceptation, it should be demonstrable in the fossil record and it is not.Its not just the "Missing Link" that kills the thory of evolution, its that millions and even billions of "Missing Links" that should exist if species to new species evolution ever happened.
Can anyone actually name any one "Fact" of evolution which can be shown to be a incontrovertible fact? If there truly is "Overwhelming Evidence", then this question should be a simple one to answer.

yeah i understand the issue.although most of what i know about this subject probably might be false, it is what i was taught and theres no need to take it so personaly.and instead of just sayin its wrong y dont yall prove it wrong with facts. plus i already know that yall r probably gonna say that fossilization is rare and thats y alot of the missing links havnt been found.anyways i thought this was a site to debate the topic, but it seems to me if someone doesnt have the same views as u then yall get real mad and just start sayin that im wrong.if i am actually wrong and all of what i said really is false, then i appologize.

yah man its cool, i just proposed the topic. ill take it slow though and finish up the other one

yeah its all good man, i appriciate the advice
