Answer 20

You can call it a biological anomaly. It is a result of a mutation from legless to with legs, and apparently the 'with-legs' survived better, thus the legless became extinct due to competition and natural selection(this selects the fittest of a species). So humans, or whatever we were then started having legs. Read up on the geological time scale and Darwin's theory of evolution for a start.

Answer 21

From an evolutionary point of view, it was more beneficial to have them than not. Any trait in any living thing has benefits which help survivability to procreate. Mutations are happening ALL of the time to every living thing. DNA does NOT reproduce itself exactly every time it divides. Mutations can be good, bad or neutral.  Good things which enhance survivability carry over to offspring as do neutral things which neither help nor hurt the chance of having offspring, but bad things die out relatively quickly. If you do not believe in evolution, then you can blame it all on your personal choice of a god or gods, or a creator or even an intelligent designer...

Answer 22

Many reasons first off all it is evolutions process. The thing is why we have two legs and way we are walking on and have hands. Again Many reasons first it cost you less energy to walk on two and that is great for survival. Second it is better because you can see predators when you get up. The development of hands also made us have two legs this contributed to the development of the intellect.

Probably started as curiosity about fires and and maybe when food gatherers had found nut.

So it is a process that happened before the Homo Erectus (the upward man).

There is also and sexual benefit to the two legs(a lot of sexual poses) we all know how much we think of s*x so this two must be the reason for the early humans.

Why we like girls with long legs and boys with big torso (see about monkeys sexual dimorphism).
