According to Darwin’s theory we must strive to protect ourselves at the cost of other species.

Theories about how things work do not prescribe values.

[Kadric]

In this case they do. According to his theory a species is not only entitled but demanded to do anything in their power for further survival. No matter the fall out to other species. Other wise his whole theory falls apart once you limit a species to moral considerations for other species. For at that point you no longer have survival of the fittest but of the willing. Which throws out the theory.
