The source is in post#1651 (or should I repost it again since perhaps you will deny that I ever posted if I just give you a post#). However, it is very dishonest of you to ask for this proof since you know quite well that science has been saying for decades that man and apes have a common ancestor not that man descended from monkeys as the charlatan Darwin said.
"Evolutionists" (i.e, mainstream science) say that apes diverged from monkeys something like 30 million years ago. Don't make me look it up.
"Evolutionists" say that the ancestor of that "common ancestor of extant apes and humans" was on the "ape" side of that divide.
Any way you look at it, "evolutionists say" that your ancestry comes down through the apes. If that bugs you, at one time rather earlier it was primitive chordates.
Charlatan? Did Darwin habitually quote people out of context? Did he lie (ie try to deceive, as opposed to merely being mistaken?) Did he call other people liars and frauds? Did he make up evidence?
This habitual name calling tells me that you know you're wrong.
