The wild ancestors of domestic pigs belong to the species Sus scrofa, commonly known as the wild boar. 

Wild boars are the ancestors of most pig breeds, except domesticated pigs in Timor and Papua New Guinea. 

This species is distributed across various continents, including Europe, Asia, and North Africa. 

The wild boar is a highly adaptable animal, capable of thriving in a wide range of environments, from dense forests to open grasslands. 

DNA analysis suggests that pigs shared a common ancestor with other even-toed ungulates, such as deer and giraffes, around 40 million years ago.

Over time, they evolved into distinct species, and the wild boar we know today is the result of this long process of natural selection.

Wild pigs vary in appearance depending on their specific subspecies and geographic location. 

Wild pigs can range from 100 to over 600 pounds, with males typically larger than females. 

Some individuals have been known to grow even larger under favorable conditions. 

These creatures generally have a stocky build with a barrel-shaped body supported by short, sturdy legs.

Their snouts are elongated and adapted for rooting in the ground. 

Wild pigs are known for their complex social hierarchies. 

They often form groups called sounders, consisting of several females and their offspring. 

Males, known as boars, typically live solitary lives or form loose bachelor groups. 

During the breeding season, dominant boars may compete for access to females. 

Wild pigs are primarily nocturnal, meaning they are most active at night. 

They have keen senses of smell and hearing, which help them navigate in the dark.

While the domestication of these animals had many benefits, several challenges were faced.

These animals were fierce defenders of their territory and would fiercely resist any attempts at control. 

Early humans had to develop techniques to subdue their wild instincts and make them more docile. 

This required selective breeding over many generations, favoring those pigs with calmer temperaments. 

Pig domestication techniques were typically passed down through oral tradition.

Ensuring that this knowledge was preserved and passed on to future generations was crucial for the continued success of pig domestication.

The Domestication Process

Pigs that exhibited more favorable traits were selectively bred, gradually leading to the development of distinct domesticated pig breeds. 

Early humans constructed simple enclosures made of wood, stone, or other locally available materials to prevent their domesticated pigs from wandering off and protect them from predators. 

These enclosures served as primitive pig pens, keeping the animals contained. 

Early humans also had to contend with diseases that could affect their pig herds. 

Although their knowledge of veterinary medicine was rudimentary, they learned to identify and isolate sick pigs to prevent the spread of illnesses.
