This is a very interesting question!  Many famous evolutionary biologists have had cracks at answering similar questions.  The basic idea is that over the course of evolution - from ancient fish to ancient amphibians to ancient tetrapods - there were constraints in the development of the body plans to make a pelvis for holding the hindlimbs and a shoulder girdle for holding the forelimbs.  For physical reasons these two morphological features have not evolved in other locations along the body, because of this, tetrapods have only four legs.

most mammals have four appendages, they just evolved differently. humans evolved into arms and legs with very different uses. rodent type animals have front feet they can use as hands, as do most monkeys. beasts of burden and their predators maintained four legs for obvious reasons.

Animals have 2 or more. Humans have 1. \n\nLook at a cat or dog for an example of a double eyelid. They may have their outer lid open but there is a membrane underneath that slides back and forth to block out light or let it pass through. That is something that people just don't have.

Well in theory, if a large cat were to have uniform spacing of dark and light spots on it, then the number of spots would be about 1/7 of the number of hairs on it's body.  There are appx. 100,000 hairs on the human head, so I might imagine that there are as many as 1 million on the body of a leoard.  That would be about 150,000 spots, except at that ratio it would only appear as a shade of color, so it would have to be significantly less than that when the human eye could see individual spots, I'd guess at least 3 hairs between each spot.\n\nSo based on my assumption of 1 million total and about 3 hairs in 6 directions (commonly accepted spread in geometric world, look at a Chinese Checkers Board).  But the spot itself would probably have to have a minimum of 3 hairs in it to be seen.  So 3/21 or 1/7 like I sid rearlier so 150,000(142,000) number was about right.\n\nI don't know the exact numbers, but I'm sure 150,000 spots would be well within the knowledge of God if a person has 100,000 hairs and he knows them all.\n\nMatthew 10\n29Are not two sparrows sold for a penny? Yet not one of them will fall to the ground apart from the will of your Father. 30And even the very hairs of your head are all numbered. 31So don't be afraid; you are worth more than many sparrows.\n\nAlso recorded in Luke 12

Actually, the statement is not true. Most creatures in the world don't have four legs. Insects, with 6 legs, are far more abundant than all four legged creatures. \n\nHowever, the main groups of vertebrates - amphibians, reptiles, mammals and birds all evolved from a common tetrapod (meaning four-legged) ancestor. This is the reason they all have four legs, even if they have subsequently lost them (such as snakes, whales, etc). \n\nFish are also vertebrates. However, they are an evolutionarily older group, and the tetrapod ancestor of the other vertebrates is believed to have evolved from sarcopterygii, which evolved from lobe finned fishes.
