EVOLUTION:

From a little pool of different molecules, binding together to form a little more complex molecules, complex molecules to even more suffisticated molecules we more likely know as the amino acids, from amino acid to proteins from proteins to simple life, and then on to complex life such as humans. This is the basic idea that most of us have of evolution, but if you look at it closley it is much more than just this. evolution is the story that explains to us the origin of life. As how life came to a stage as we know it today. The theory of evolution have given answers to a lot of questions that remained unanswered for along time. so here is a little review of what exactly happened in our little story of evolution......A long long time ago our earth as we know it today was completly different. there was no sign of life and the weather was also bad. The oceans were showing their power to the full extent. lightning storms were normal daily rutine, the sky was filled with clouds rarely did sunlight reached the ground.
Now one day something strange happened in a pool of water little molecules somehow got attracted to each other and formed more complex molecules konown as the amino acids, as most of us know that amino acids are the basic components that the proteins are made of, so again with some more strange happenings these amino acids came together to form a very complex molecule called proteins, and finally these proteins formed a type of a very simple life. this organism was very simple and it fed on proteins and it divided into two as it got bigger and hence it reproduced. But scientist don`t mark this as the starting of life (i don`t know why).
the beginning of life is marked with the formation of algae. From here life divides it self into other parts, (remember this was all happening in the oceans) basically into plants,animals,fungi,bacteria,etc...then life slowly moved toward the ground. The ground gave life lots of diversity in the living condition and the enviornment from there life became more and more complicated. finally giving rise to humans..

basically why does evolution occurs is a story in itself. The simple clue to this story is ADAPTATION
