Re the Star Child: Congrats to Lloyd, for sticking with it and going that extra mile to get proof. To those who are bagging him, let me state that there are 342 base pair sequence strands that are unlike anything known on this planet. That is a huge amount. If it were only 10 or 20, I might be saying the same thing, but with the dna testing that has been done, it proves that there is no similarity known.

I apologize if someone has already brought this up - I skipped to the end after reading the first two pages and had an epiphany of my own:
What about the chromosomes? If this "Starchild" was the product of an alien father and a human mother, surely the number of chromosomes would be different. Even in humans that positively have two human parents, we see the number of chromosomes differing from the norm with genetic abnormalities like Down's Syndrome. I would think that in a creature whose mtDNA is as different as is being claimed, then the chromosomes would also be affected in a MAJOR way.
***Three hours after writing the above bit***
After googling all night, and brushing up on my microbiology, I have come to the conclusion that there is no way to determine the number of chromosomes that were present in this skull. I am leaning towards a totally terrestrial condition such as progeria or hydrocephaly to provide the explanation for the shape of this skull.
Thanks for the gray matter workout though. I'd forgotten how much I'd forgotten about microbiology since college.

When was it established that Aliens have sperm? Or genitalia, for that matter?

What is taking so long?
I watched an episode of Jeremy Kyle once (ONCE!) they did a DNA paternity test and had the results before the end of the show!
I know the police forensics can distinguish human DNA samples from known animals DNA, and it normally takes a few hours.

mtDNA can be differentiated from what people consider to be the normal human genome. If memory serves me correctly, it is a remnant of a endosymbiotic bacteria that contains genes essential to mitochondrial functions within a cell.
It does not recombine when a child is conceived, and is passed down the maternal line.
I'm not saying this is definetely real, but the science adds up.
To add: It is only made up of around 16,500 base pairs. So 800-1200 is an absolutely HUGE difference.
They have the science right, but I guess you have to question whether the data is actually real.
DNA testing in 1999 at BOLD, a forensic DNA lab in Vancouver, British Columbia found standard X and Y chromosomes in two samples taken from the skull, "conclusive evidence that the child was not only human (and male), but both of his parents must have been human as well, for each must have contributed one of the human sex chromosomes". Further DNA testing at Trace Genetics, which specializes in extracting DNA from ancient samples, in 2003 recovered mitochondrial DNA from both skulls. The child belongs to haplogroup C. Since mitochondrial DNA is inherited exclusively from the mother, it makes it possible to trace the offspring's maternal lineage. The DNA test therefore confirmed that the child's mother was a Haplogroup C human female. However, the adult female found with the child belonged to haplogroup A. Both haplotypes are characteristic Native American haplogroups, but the different haplogroup for each skull indicates that the adult female was not the child's mother.
The human family tree just got another -- mysterious -- branch, an African "sister species" to the heavy-browed Neanderthals who once roamed Europe.
While no fossilized bones have been found from these enigmatic people, they did leave a calling card in present-day Africans: snippets of foreign DNA.
There's only way one that genetic material could have made it into modern human populations.
"Geneticists like euphemisms, but we're talking about sex," said Joshua Akey of the University of Washington in Seattle, whose lab identified the foreign DNA in three groups of modern Africans.
These genetic leftovers do not resemble DNA from any modern-day humans. The foreign DNA also does not resemble Neanderthal DNA, which shows up in the DNA of some modern-day Europeans, Akey said. That means the newly identified DNA came from an unknown group.
"We're calling this a Neanderthal sibling species in Africa," Akey said. He added that the interbreeding likely occurred 20,000 to 50,000 years ago, long after some modern humans had walked out of Africa to colonize Asia and Europe, and around the same time Neanderthals were waning in Europe.
Akey said that present-day Europeans show no evidence of the foreign DNA, meaning the mystery people were likely confined to Africa.
