Domestic pigs to razorbacks?

Pigs will certainly revert to a wild form when they go feral. However it takes more than one or two generations. At least 20 gnerations would be required to go from the more higly modified domestic forms to a true feral.

And yes, it is hard evidence of the reality of evolution. The population has changed to adapt to its environment, and htose change are heritiable because they are due to changes in gene frequency. That is the textbook defintion of evolution.

Not that any more hard evidence of evolution was required.

Razorback Pig

Actually it has been shown that due to human breeding many species of animal have bred out their aggressive behaviour. However the genetics for their aggression is still present.

An example of this was conducted on foxes in siberia, where a new breed of dog was developed by breeding the cute foxes and weeding out aggression.

A pig released into the wild will over several generations develop larger tusks and more agressive behaviour. This is not evolution, it is merely them resorting to behavior and genetics that were hidden by human breeding patterns.

Generally humans are unlikey to breed a vicious pig with a sow, they will try and seperate (or eat) the vicious pig... thereby limiting the genetic pool.

RE:

Domestic pigs to razorbacks?

Apparently, when placid, nervous, bare-skinned, pink domestic pigs are released or escape into the wild, after just one or two generations, they mutate into the extremely aggressive, hairy, tusked, different-coloured 'razorback' pigs - firstly, is this true? And secondly, this is hard...

Yes you have it mostly the way it is. Domestic pigs except for the brood sows never get very old. They are sent to market and you can have pork chops. Pigs have been domesticated for thousands of years. Some return to the wild if left to run free. They have to forage for their won food so they usually are not as fat as the domestic. As they get older the tusks grow and are used as weapons. Most pig farmers remove the tusks to prevent harm to the other pigs and himself. Hogs can be very dangerous if they want to be. They are fast and strong. If they are not used to people then they will naturally be on the defensive. Pigs are not stupid at all. They are one of the smartest of animals. They can survive in many different environments.

It is true. And as far as the dominant genes presenting themselves due to being reintroduced into a wild environment where they can mate with other wild hogs or simply combining their genes with those in their own family as being hard evidence of evolution may be a pretty short path to the truth. though a little stilted due to the fact that they are not evolving new traits only going back to those derived through trial and error through the ages. More like adaptation which leads to evolution, but it does prove how ingrained our genetic traits really are. Mother nature sure doesn't mess around. She works things out the hard way, what works works, what doesn't dies..

No no no. IF in the wild there are feral pigs of a specific species, then maybe, but it would take more than 2 generations, 4 or 5 generations minimum.

I doubt that is true. I think they are two different subspecies but are related. It wouldn't be a sign of evolution, it would be a sign of adaptation. Evolution would be a pig turning into a horse or something like that. Growing tougher skin is a sign of adaptation.
