In humans, glycogen is synthesized primarily in the liver and skeletal muscle.
Humans are produced via sexual reproduction. That gives genetic diversity. You do not get such genetic diversity in case of the parthenogenesis. It is poor mode of reproduction.
No, burping can occur in many mammals, as well as birds and some reptiles. It is a natural process that helps release excess gas from the digestive system.
There are approximately 7.8 billion humans on Earth, each with a unique combination of genetic material inherited from their parents. This genetic diversity is vast and virtually limitless due to the random nature of genetic recombination and mutations that occur during reproduction.
Lactose metabolism occurs in the small intestine of humans. It begins when lactase, an enzyme produced by the small intestine, breaks down lactose into glucose and galactose. This process allows the body to absorb these simple sugars for energy.
Probably, the most basic answer anyone can give, is because humans exist. While humans are alive, wars will happen.

We came from Africa.

Humans have no control where and if tornadoes occur.
example of these rhythms in both humans and animals is the circadian rhythms which occur every once a day.
No, not particularly, some pain and swelling may occur.
Yes. Recent DNA testing has proved that interbreeding did occur.

Homosexuality doesn't occur in "cases." It's part of human nature, and has been around as along as humans have been around.
