Peking Man was Homo erectus.
I'd be very skeptical about any date in the region of 100,000 years that wasn't accompanied by first rate archaeological and dating techniques. Carbon dating is essentially impossible at that age, and uranium dating imprecise. Indeed, the idea that Europeans, Asians and Africans may have diverged far earlier is intriguing, and would drive the 'race is mythical' people bonkers; since we consider H. erectus a different species from H. sapiens, then consistency would demand the (at least) three distinct descents from H. erectus be three distinct species. I can't think of anything more politically incorrect, offhand. :-)
However, the preponderance of the evidence does still seem to support 'Africa first'. If you push the divergence date back to 1/4 million years, you have to assume we all evolved from Homo erectus almost in perfect parallel; typical Mongoloids, Caucasoids and Negroids are far more similar to each other than to H. erectus or even H. neanderthalensis.
