Evolution simply means "change".
Millions of years ago there were homo sepians who were ur ancestors and now we have develop. thus is called evolution.
Evolution takes time. it is not drastic.
HERE IS YOURS ANSWER MY SISTER
Evolution is change over time that happens in a specific way. It's a phenomenon inherent to systems that meet a few criteria:
1) There are entities that replicate themselves. In biology the entities we're interested in are usually organisms: bacteria, cats, trees, whatever. But these entities could also be computer programs, populations of biological organisms, languages, ideas (memes) etc.
2) There is variation in the population.
3) The variation isn't constant; the population of whatever entity you're interested in doesn't have the same characteristics generation after generation. This is more of a technical criterion. Theoretically, a population of entities that meets the two criteria above could stay the same generation after generation–be in equilibrium–but in biological evolution this doesn't really happen except in the short run.
In biology, these changes comes from mutation, from recombination of existing genes, from organisms migrating into a new population, from selection of mates etc.
The "survival of the fittest thing" is evolution by natural selection. There are other types of evolution as well. In this kind of evolution, the replicators are organisms and the variation comes from mutation and recombination of existing genes.
