pigs’ skin is used for grafts for humans, because of its relative human-compatibility.

Cannibals have referred to human meat as “long-pork”. — Michael Ossipoff
That sounds like the extent of the "evidence" he's presenting. At least per the article you're quoting. — Terrapin Station
Since I've mostly retired, I lose track of time sometimes. When I read the OP, I thought maybe it was actually April 1. — T Clark
I have read in a number of places that geneticists have determined that about 4% of the human genetic makeup comes from Neanderthals. There may also be a contribution from Denisovians. Do you really think they would have overlooked pig DNA?
Horses cannot mate with donkeys and give birth to fertile offspring, but you want us to believe that pigs and chimps can?
Here's another reason to miss TimeLine. She would have opened up a can of Australian whup ass on this pseudo-science in three seconds.
McCarthy is a world-class hybridization-geneticist. Where do you find that he's wrong? — Michael Ossipoff
I can't find any evidence on the web that he is a "world-class hybridization-geneticist — T Clark
I'm not a biologist or geneticist, but I am certain that pigs cannot interbreed with chimpanzees and produce fertile offspring. — T Clark
Over the long term, though a hybrid of pig and chimp seems extreme and unlikely to survive, given natural perversity, it might happen enough times for one or two to get lucky with the fertility. At least I don't see much justification for a blanket dismissal before consideration. It does seem to explain some curious facts that are otherwise odd coincidences. — unenlightened
This is all well and good, except it never happened. — T Clark
https://www.foxnews.com/health/why-pigs-are-so-valuable-for-medical-researchAccording to Swindle, many of the pig’s organ systems are 80 to 90 percent similar to the corresponding systems in humans – both in anatomy and function. The system that matches up best may be the cardiovascular system, as a pig’s heart is about the same size and shape as a human heart. Pigs develop atherosclerosis – artery plaque buildup – in the same way that humans do, and they react similarly to myocardial infarction, the classic heart attack.
https://en.wikipedia.org/wiki/Sheep–goat_hybridAt the Botswana Ministry of Agriculture in 2000, a male sheep impregnated a female goat resulting in a live offspring. This hybrid had 57 chromosomes, intermediate between sheep (54) and goats (60) and was intermediate between the two parent species in type. It had a coarse outer coat, a woolly inner coat, long goat-like legs and a heavy sheep-like body. Although infertile, the hybrid had a very active libido, mounting both ewes and does even when they were not in heat.[2] He was castrated when he was 10 months old, as were the other kids and lambs in the herd.[3]
A male sheep impregnated a female goat in New Zealand resulting in a mixed litter of kids and a female sheep-goat hybrid with 57 chromosomes.[4] The hybrid was subsequently shown to be fertile when mated with a ram.[5] In France natural mating of a doe with a ram produced a female hybrid carrying 57 chromosomes. This animal backcrossed in the veterinary college of Nantes to a ram delivered a stillborn and a living male offspring with 54 chromosomes.
And I must now emphasize a fact that I, as a geneticist, find somewhat disappointing: Though there are other ways of detecting them, with nucleotide sequence data, it can be very difficult to identify later-generation backcross hybrids derived from several repeated generations of backcrossing (and this would be especially true of any remote descendants of backcross hybrids produced in ancient times, which is what I'm proposing humans may actually be).
but 80 to 90 % is a lot of similarity — unenlightened
Humans share the same sorts of genetic similarities — Tzeentch

Looking at a subset of the listed traits, however, it’s clear that the other parent in this hypothetical cross that produced the first human would be an intelligent animal with a protrusive, cartilaginous nose, a thick layer of subcutaneous fat, short digits, and a naked skin. It would be terrestrial, not arboreal, and adaptable to a wide range of foods and environments. These traits may bring a particular creature to mind. In fact, a particular nonprimate does have, not only each of the few traits just mentioned, but every one of the many traits listed in the sidebar. Ask yourself: Is it likely that an animal unrelated to humans would possess so many of the “human” characteristics that distinguish us from primates?
The guy is a kook. — I like sushi
Maybe you could tell me when abouts he thinks this happened? — I like sushi
if a chimp crossed with a pig to produce a female hybrid, then the hybrid will have mostly pig mitochondrial DNA, won't it...? Is that part of what happened? I'm not sure how much mitochondrial DNA is passed on by a male father....I think there is mitochondrial DNA from the father present in the sperm, but not sure if any of that ends up in the offspring.. — wax
