Answers
Humans, whose scientific name is Homo Sapiens are believed to be evolved from apes. There are many scientific evidences like the matching pairs of amino acid sequences, homologous and analogous structures. Apes are said to be evolved due to the natural selection. In other words, the apes were forced to evolve due to nature. The nature forced apes to walk on two legs, changed the skull structure. These changes would be beneficial for hunting and gathering. There are 5 steps for any organism to be evolved.
1) Variation
There were any animals living on the land. Every animal differed from the other.
2) Over-reproduction
Organisms reproduced rapidly.
3) Competition
There is a competition for various resources like food. Apes and other animals fought for these resources
4) Survival of the fittest
Organisms with the best features survive and get the resources. Apes mutated their genes to be the best fit for the nature.
5) Descent with modification
The apes with the mutated genes lived and passed it on to their next generation and these next generation started to evolve for millions of years and finally turned into human.
