There is still controversy over whether life on this planet (and therefore humans) was created by evolution or by outside intervention - they were created. Genetic tests in recent years show that there are fragments of something that does not come from this planet in our genome and therefore could not have arisen by mere evolution - at least not on Earth scales. In contrast, we have living evidence that nature can cope and indeed form evolution to develop animal species.

So is the question of whether the path leads again between the two extremes? Another question is how does an animal species fall in the name of humans?
