It is certainly true that our species is almost certainly not descended from any present-day ape species. However, the common ancestor would have been very simian, and very worthy of the title "ape".
And fossil hominids show show lots of intermediate features.
So this is a bit like quibbling over whether dogs are really descended from wolves.
And on the subject of dogs, the sequencing of their genome will get started in a few months, according to
this article. Boxer dogs are the first to be sequenced, because they are relatively inbred, resulting in smaller amounts of confusion from polymorphisms. And when they are done, about a year from now, then 10 - 20 other breeds of dogs will have their genomes probed. It will be interesting to locate the genes that make a Great Dane so much bigger than a Chihuahua -- which are likely to be a very tiny fraction of the genome.
