Solution

Evolution is simply the generation of diversity and the shaping of diversity by environmental selection. Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The progressive trend in evolution seems to be that more and more complex body designs have emerged over time with better distribution of functions. In fact, one of the simplest life forms like bacteria – inhabit the most inhospitable habitats like hot springs, deep-sea thermal vents and the ice in Antarctica. This is the reason why evolution is not equated with progress.
