@Mathius_dragon Sorta. We're not decendents of any extant ape other than other humans. Just like we are also technically monkeys, since you don't really grow "out" of your previous genealogical group. Like how if one of your ancestors was royalty you have royal blood, or have Haitian ancestry from multiple generations ago. Just on a much, much larger scale.
As for the OP, if he believes evolution would explain a lot of things, why not humans? It's not like there is some arbitrary cutoff or random spontaneous generation to flesh out the gene pool.
