Very basic genetics tells you that you must match up chromosomes. Humans have 46 chromosomes, the other great apes have 48, pigs have 38: http://en.wikipedia.org/wiki/List_of_organisms_by_chromosome_count. Try to pair 38 chromosomes with 48, you don't end up with 46 functional chromosomes. I feel quite comfortable in rejecting that hypothesis.

Very basic genetics are not always correct genetics. It is quite possible for two species of differing chromosome counts to mate, and for the offspring to be fertile as a backcross...

Can you give me a reference? I want to know more.

Sheep-goat hybrid at Wikipedia.

PubMed abstract claiming a successful backcross.

Basically, Sheep have 54 chromosomes, Goats 60, and hybrids 57 - and the hybrids have been backcrossed before. It seems that the backcrosses inherit traits from their grandparent.

Thank you. I wouldn't have thought this possible. Pity that downloading the paper would cost $46. I would like to know what was lost and how you can get a viable organism with several chromosomes gone.

No way could a human-porker hybrid be fertile.

Alternative hypothesis: Maybe humans mated with something to produce pigs.

I have been trying to incorporate the possibility of pig ancestry into my sense of identity. I now experience a feeling of kinship with pigs, and I feel like a monster from Dr Moreau's lab.

If any of this turns out to be true, how do you think humanity will deal with the information?

Since pigs didnt have their human like traits until after domestication- it would make more sense to suggest that domestic pigs were spawned by humans buggering captured wild boars- then the other way around.

More sense than the notion that humans are somehow the product of chimpanzees getting it on with the not-yet-very-humanlike wild boar precursors of domestic pigs.

Not sayin' the former is likely either. But its the far less idiotic of the two theories.

It could be...

DOLPHIN - 44 (intelligence, cognition, advanced socialism, advanced sexual complexity, self identity, etc.--attributed mental/emotional/higher traits)
and CHIMP - 48 (minor cognition, advanced dexterity, social hierarchy/governance, social rituals, alpha aggression, etc.--attributed physical/motor/instinctual/alpha/ lower traits)
=HUMAN - 46

...Or any similar combination, and of course, created in a lab, unless you are more inclined to imagine a more colorful scenario.


Hi, btw, I'm new. Sorry about the informality

We might as well be half of an Aquatic Rat (92 chromosomes)

...Because even a potato has 48 chromosomes -- same as our supposed (theorized) ancestor

Welcome!



This is a little off-topic, but if you could trust humans to be mature about it, I would support making alterations to our species to try to eliminate some of our more glaring defects,and allow us to live in extreme environments. The problem is that it will probably result in the commodification of stupid genetic alterations and slave species.

The informality is no issue at all!
In that scenario, humans would be infertile. None of the chromosomes would be able to find their analogues. Human would probably need to live as tetraploids, with two copies of each "chimp" chromosome and two copies of each "dolphin" chromosome, giving them 92 chromosomes.

I'm guessing thousands - if not millions - of lonely farmhands across the world have their fingers crossed for this to be true.

Never having been to North Wales, I couldn't comment.

One pair of our chromosomes is actually two chromosomes jammed together end-to-end. So we actually do have 48 chromosomes.

So we have the same number as do potatoes.

Potatoes already have eyes.

Maybe one spud a million years ago also had a brain- and led to us!

The local lonely farmhands are all about sheep. The sheep/human hybrid matter was settle back in 1986, when the local farmer's council decreed that a tourist who'd come by wearing a fleece was evidence enough.

Besides, I'm not Welsh. I just live here for the sheer misery of it.

Hmmm...

I take it that 'North Wales' must be the "West Virginia" of the UK ( the butt of certain kinds of jokes).
