Because the pig length is not aerodynamic, the pig cannot fly. You can put the pig on the plane and let the plane take your pig fly.

Because: pigs fly in the air, pigs need to have upward buoyancy to overcome gravity, where does this buoyancy come from?
First of all, the air density is extremely small and can not provide enough buoyancy, so it is necessary for the pig to create its own conditions to give the ground a downward force, so as to obtain an upward force by itself, obviously, the pig does not have such physiological conditions, so the pig can not fly.

Yunnan Xinhua Computer School:
That's because the pig didn't aspire to fly. As long as you are determined to fly, in the course of hundreds of millions of years of evolution, pigs have long been flying. Just as if you don't have a will, you can't do anything. Secondly, it's a pig!

Pigs don't have wings so they can't fly, and how can pigs fly when they're so fat.
-
Because the pig does not stand on the tuyere, as long as it stands on the tuyere, the pig will fly.
First, pigs have not evolved wings to fly, so they can't fly.
Second, the body density of pigs is relatively large, and there is no way to fly with the help of ordinary wind.
Thirdly, no one takes pigs on planes, so pigs can't fly.
Therefore, pigs can fly only in some special circumstances, for example, when the wind is strong enough, even if they do not have wings, even if they are as fat as pigs, pigs can fly. For example, when there is a tornado, or when a strong typhoon of 12 is blowing, pigs can fly. There is also the fact that pigs are taken to the sky when they are caught by some large birds of prey.

Okay, why don't pigs fly? The pig can't fly, he's going to be skinny, so he doesn't have wings, he won't spend, thank you.

This is a brain teaser, the answer is only known to the pig, or the pig also wants to know (the metaphor is that the person answering the question is a pig), this kind of Wenzi nuclear word game has an obvious feature, the question is very ordinary, but the answer is very annoying or very funny, sometimes, it will play an indirect role in scolding. Once cracked, it makes people squirm. So asking about brain teasers also has the effect of adjusting the atmosphere at a party.
This brain teaser also alludes to an idiom: Fu Liang pretends to be a pig and eats a tiger.
Because since humans raised them as poultry, the wings of chickens have degraded after training. At the same time, I slowly got used to the living environment on the ground, and over time, the wing muscle tissue deteriorated, and the body became heavier and heavier. This has been passed down from generation to generation, so chickens nowadays hardly fly. >>>More

Apples are the fruits of the apple tree that are produced by the apple tree in order to reproduce their offspring. The ovary of the flower develops into a pulp, which plays a protective role in order to prevent the seeds from being accidentally injured. When the seed is ripe, it signals to the apple tree, and the apple tree stops providing nutrients to the apple, and the pedicle will lack nutrients and shrink, and it will fall off when it can't stand the weight of the apple. >>>More

By definition, birds are bipedal, homeothermic, oviparous, forelimbs that have evolved into wings, and have a hard peck. In terms of physiological characteristics, the skeleton of birds is hollow and highly healed, and the sternum is well developed except for the flat-chested order (that is, a type of bird represented by ostriches), which is convenient for the attachment of the pectoral muscles; body surface feathers; When breathing, a microtrachea is used for gas exchange, with an air sac; Toothless, with a short digestive system and the use of uric acid for metabolism, ostriches also have these physiological characteristics. >>>More
