Domestic pigs have both hair and tusks...the tusks are removed very close to birth for the safety of humans and other pigs. The hair is generally sparse compared to wild pigs but there are some domestic breeds that are hairier than others.
to defend themselves
no not in a barn. only in the wild .
answer is warthogs
They do. Pigs are very adaptable. Feral pigs are a big problem in some areas.
Primitive species of pigs (such as bush pigs and wild pigs) have sharp tusks which are used to dig up roots. These roots and other similar plants such as tubers form the foundation for a wild pig's diet. Contrary to popular belief pigs are mainly herbivorous animals and their tusks are not used in hunting prey. --------------------- I take it he question is asking why natural selection favored pigs with sharp tusks. These tusks are offensive and defensive weapons, effective tools for foraging, and likely also used in courtship display. The animals that lacked them would not have been favored by natural selection for these reasons. The animals that lacked them would have been less able to forage for food, less able to defend themselves from rivals and predators, and quite probably less attractive to the opposite sex. These factors would gradually lead to a larger ratio of pigs with pronounced tusks in the population until eventually it became a common trait for the group.
warthogs == Boars. A boar is a wild pig with tusks & bristly (coarse) hair. A warthog, though similar, is covered in warts. The difference between the two can be more easily explained in a dictionary.
No have you ever seen a wild pig their called Bores they get tusks and can grow to over 800 pounds.
Wild pigs are close relatives of domestic pigs. Wild pigs can adapt to many different kind of habitats, but they prefer forests or wooded areas. Tusks on the bottom lip are one of the most prominent features of a wild pig.
The males grow tusks and on occasion so do some females.
The African wild boar is the tusked, wild pig of Africa. The boar's scientific name is Phacochoerus africanus. The boar's tusks are hunted by poachers. The tusks traditionally are used as knife handles. But they also have artistic uses.
