Baffling 400,000-Year-Old Clue to Human Origins

NY Times wrote:Scientists have found the oldest DNA evidence yet of humans’ biological history. But instead of neatly clarifying human evolution, the finding is adding new mysteries.
In a paper in the journal Nature, scientists reported Wednesday that they had retrieved ancient human DNA from a fossil dating back about 400,000 years, shattering the previous record of 100,000 years.
The fossil, a thigh bone found in Spain, had previously seemed to many experts to belong to a forerunner of Neanderthals. But its DNA tells a very different story. It most closely resembles DNA from an enigmatic lineage of humans known as Denisovans. Until now, Denisovans were known only from DNA retrieved from 80,000-year-old remains in Siberia, 4,000 miles east of where the new DNA was found.
The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. They might have interbred, swapping DNA. Scientists hope that further studies of extremely ancient human DNA will clarify the mystery.

Just out of curiosity:
How are "evolutionists" proven wrong by this?
Also, what alternative do you propose?

The older findings suggest that rather than humanity springing from a common ancestor, the existing races are the continuation of older strands which existed in pretty much the same form now as they did hundreds of thousands of years ago. It would appear that races of humanity have become extinct, but none have 'evolved'. I'm afraid this leaves more questions than it answers.
What alternative do I propose? I find that the accepted alternatives seem wholly inadequate, but I also don't place much faith in the idea of lifeforms coming from outer space to colonise us - which is indeed a theory which is followed by some. I find this area fascinating - especially the archæological evidence which constantly pushes back the dates at which civilisation is deemed to have emerged - but the more I learn, the more I need to learn! Maybe that's a cop-out, but honestly, I have no answers, only many, many questions!
