Pig extinction
Why Haven’t Pigs Gone Extinct in Evolution?
Pigs reign undefeated in evolution thanks to their extraordinary reproductive power, “land tank” physique, omnivorous diet, and deep symbiosis with humans. Discover the four survival secrets that keep pigs thriving.
🐖 The Four Survival Secrets of Pigs
1. Reproductive Power — The Ultimate “Breeding Factory”
- Over a dozen piglets per litter, with a gestation period of just 114 days
- Rapid weaning: piglets weaned at 1 month; sows estrus again in just 10 days
- Boar stamina: can ejaculate up to 0.5 kg over 30 minutes in one session
2. Combat Strength — The “Land Tank” Physique
- Adult wild boars weigh up to 700–800 jin (≈350–400 kg)
- Thick skin & bristles: natural armor against predators
- Aggressive temperament: fierce defense and formidable in battle
3. Diet & Adaptability — The “Universal Eater”
- Non-picky: eats bark, roots, insects, eggs, even rodents
- High adaptability: farm pigs revert to wild traits within months—growing tusks and fending for themselves
- Snake venom resistance: innate immunity lets them treat venomous snakes like “spicy snacks”
4. Human–Pig Symbiosis — The “Survival Insurance”
- Domestic pigs guaranteed survival as a meat source for humans
- As long as humans thrive, pigs have safe refuge
- If humans vanish, wild boars’ hardiness and adaptability will still sustain them
Conclusion
From staggering fertility and armored bodies to fearless omnivory and a unique bond with humans, pigs have honed every trait to perfection on evolution’s stage. They are, quite simply, evolution’s unbeatable champions.
