Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike.

Carnivorous boars?

This is a question that appeared today in my mind. I remember talking with my grandmother about how in her village little kids couldn't get close to the pigs because of the danger of being killed and maybe even eaten. I researched a bit and it seems like there have been various cases of wild boars killing and eating small animals, including cattle. With the dissappearence of big predators like wolves or bears in western Europe, could it be possible for boars to evolve into predatory animals?

Tetraconodonts had teeth similar to entelodonts, so yes.

Perfectly possible, pigs are omnivores and enthusiastic meat eaters, and there have been several predatory ungulates, mesonychids, cetaceans and Andrewsarchus.

Their hooves would limit the ways they could hunt, but they could still evolve into bear-like and dog-like animals quite easily.

It refers to Tetraconodontinae, an extinct subfamily of suids.

Even duikers show trends towards carnivorous behaviours. However otherwise its limited to members of the Cetaceomorpha and the tetraconodonts. Wondering if there could be ultrapredatory pigs because they are artiodactyls overlooks something: the clade is primitively omnivorous.

All living artiodactyls have a chambered stomach excepting Suidae, and three living clades are foregut fermenters having been thus preadapted. Whales go in the opposite extreme as obligate carnivores depending on jaws and teeth in the absence of claws. Its unlikely that a killer whale bite would evolve on land without a grade lacking an occlusal bite, but it would circumvent the constraint posed by hooved pig feet. Occlusal bites are lost in piscivores (toothed whales, grey seals) and insectivores (giant armadillo) and coevolves with polyodonty each time. If you can factor in such a stage then you can have a pig with a bite like an orca.

As a point of reference Andresarchus seems to be the most carnivorous entelodont and was a piscivore evolved from a pig-like ancestor. Now modify the skull along the lines above along the moderately derived Halichoerus, which is on the way to becoming something like a toothed whale with an unstable number of teeth. And then look at killer whales, Livyatan etc. So it has such a bite but probably with some heterodonty still.

Pigs are front heavy and this lends easily to a hyena or homothere gait. Grappling like a lion or a grizzly bear is improbable. However the intermediate stage of a fish eater or insectivore would lead to slender jaws and a fairly lightweight skull by comparison to warthogs or wild boar so something like a thylacine could evolve. Though they were ambush predators thylacines had a bite force suggesting they habitually took small prey, as do most canids so a predatory pig could look different.

I have predator pigs in my Neozoic project. They evolve after a thermal maximum causes carnivoran body size to trend smaller, leaving niches for large predators open.

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

Feral pigs in the united states can be predatory, I don't find it impossible for wild boars.

"Deer hunters are facing competition from a source that is mean, relentless and out of control.

The explosion of feral hogs across the U.S. is threatening the deer population -- spreading disease, dominating the food chain and even, on occasion, killing and eating fawns. In Louisiana, where there are an estimated 700,000 wild hogs, hunters and wildlife officials say they are taking a toll on the whitetail deer herd.

"They are in the marshes and beaches of Louisiana all the way up into the hills and piney woods and swamps," Jim LaCour, state wildlife veterinarian for the Louisiana Department of Wildlife and Fisheries, told FoxNews.com. "They’re in every habitat in the state."

They’re very adaptable and also highly destructive," LaCour said.

LaCour described the feral pigs, which can weigh up to 500 pounds, as "opportunistic" eaters -- omnivores that feast on anything crossing their path, including deer fawn, other piglets and dead animals.

LaCour said hogs carry many diseases, such as leptospirosis, which can infect or kill other animals, like deer, as well as humans.

"Hogs are the sport utility vehicle for disease and parasites -- they move them across the landscape," he said. "That bacteria [leptospirosis] can cause abortion in the deer – and it can kill adult deer or people."

Their presence is also detrimental to the land, forcing wildlife officials to carry out aerial gunning in certain areas "because they tear up the marsh and that leads to coastal erosion."

Hogs were first introduced to North America by Spanish settlers. The breed most commonly seen in Texas is a mixture of those hogs and Russian boars brought over more recently for sport hunting, according to the Texas Parks and Wildlife Department.

Some speculate the population boom is due to relatively recent cross-breeding in the wild. Others, like LaCour, say the popularity of hog hunting in the 1980's and early '90's led humans to move the feral pigs from confined, geographically isolated areas into places they had never been before.

Wild hogs can reproduce by the time they are 6 months old. Feral sows can have two litters per year averaging six piglets per litter, according to wildlife experts. Statisticians have determined that 75 percent of the population must be harvested to maintain a static population -- prompting Louisiana and other states to adopt liberal hunting policies when it comes to killing the hogs. Texas has the highest rate of feral hogs to date, according to environmentalists.

For deer hunter Justin Lanclos, the very sighting of a feral pig means trouble.

"If you start to see hogs in your hunting area, you are absolutely not going to see deer," said Lanclos, a 33-year-old bowhunter from Sulthur, La.

"Deer are extremely smart and elusive," Lanclos told FoxNews.com. "They just don’t like to occupy the same area as hogs."

Lanclos, the owner of retailer Louisiana Bowhunter, said he recently received a photo showing a herd of hogs -- or sounder -- running off with a whitetail fawn. The image, believed to have been taken in Louisiana, has since gone viral on social media.

"We’ve got other photos of feral hogs carrying fawns," noted LaCour. "If the hogs are coming through a field and they happen to come across it, they’re going to eat it."

Oh. I couldn't understand at first. But really, smaller carnivorans will just bounce back.

Other carnivores have coexisted with clade Carnivora: bathornithids, Homo sp. and importantly entelodonts. Things can compete with them and eke niches.

A trend within Carnivora itself is toward repeated evolution of carnivory from generalised omnivory. Such is seen to a lesser degree in other orders, including Artiodactyla, Rodentia,etc. The problem is finding some niche empty.

I think it is perfectly possible for boars to become full carnivores, but I doubt they would be able to be the dominant predators in an environment as long as members of Carnivora were still around.
