Human Chimp-Pig Hybrid Theory
Here is a compelling argument that's been shaking things up in the science world.

Dr. Eugene McCarthy, a geneticist who's proposing that humans first arose from an ancient hybrid cross between pigs and chimpanzees. Despite the large number of comments, here at Phys.org, on macroevolution.net, and on several other discussion forums, little in the way of a scientific consensus has emerged. By and large, those coming out against the theory had surprisingly little science to offer in their sometimes personal attacks against McCarthy.

And an earlier article:
http://phys.org/news/2013-07-chimp-pig-h...umans.html

He argues that humans are probably the result of multiple generations of backcrossing to chimpanzees, which in nucleotide sequence data comparisons would effectively mask any contribution from pig.

So... the Jews and Muslims are right not to eat pig? Well damn.

Is stupidity just something that comes with the name McCarthy?

The article lost any credibility with "A paper published in Nature a few years ago demonstrated that the platypus genome contains both bird and mammal chromosomes". That was debunked. The platypus has some primitive DNA and some evolved DNA, it doesn't have cross-species DNA.

And we don't have any pig DNA. [Image: cutepig23.gif]

RE: Human Chimp-Pig Hybrid Theory
This reminds me of the veterinarian Melba Ketchum who claimed that bigfoot was half-human-half-lemur. The failed results of that study resulted from using the wrong technique to analyze degraded samples.

Quote:The challenge is that the high-throughput machines typically produce short sequences that are about 100 bases long. Even the smallest human chromosome is over 40 million bases long. There are programs that are able to recognize when two of these 100 base-long fragments partly overlap and combine their sequences to create a longer sequence (say 150 bases). By searching for further partial overlaps, the programs can gradually build up longer and longer stretches, sometimes ranging into the millions of base pairs. Although this software will still leave gaps where sequences don't exist or show up at multiple places in the genome, it's still the standard way of assembling genomes from short, 100-base-long reads.

For some unfathomable reason, team bigfoot didn't use it. Instead, they took a single human chromosome and got some software to line up as much as it could to that.

There are a number of serious problems with this approach. You could have an entirely different genome present in the sequences, and the software would ignore most of it. Most of the gene coding regions are highly conserved among mammals, so they'd line up nicely against the human chromosome—in fact, they might be difficult to distinguish from it. But the entire rest of the genome would be ignored by the software. By taking this approach, the authors pretty much guaranteed they'd get something out that looked a lot like a human genome.

This sounds like what Dr. McCarthy might have done. He lined up DNA looking for similarities and found many with pigs, which are obviously mammals. It should be pointed out that genome construction was recently called into question. This article explains that assembling programs do not come up with consistent results when used by different groups, meaning each resulting genome is different. Thus, I remain skeptical of Dr. McCarthy's claims. Just because animals with widely varying chromosome counts--like zebras and donkeys--can mate doesn't mean that chimps and pigs can. Zebras and donkeys can mate because they are in the same genus. Pigs and chimps aren't even in the same order.

RE: Human Chimp-Pig Hybrid Theory
The probability of a human/pig zygote occurring is extremely low, so there would have to have been a whole lot of pig fucking going on. A lot.

The sheep would have been awfully jealous.

I hate to agree with Chas, 'cause he's a poopyhead, but I ain't seeing it. Seems more like stirring up a buncha controversy to make a name. Undecided
