I saw that old explanation "living things have an innate urge for survival" in there. Its not necessary at all, and diminishes the idea of natural selection.
Creatures/species don't get selected because of what they want. The ones that behave to avoid early death (before reproduction) are represented larger in the population. The makeup of the population shifts over time. That's it. That's about all. No need to imagine an urge.
Further, some (many) creatures die during reproduction. They have no urge for survival at all - just the opposite.
To go on, plants are subject to selection. Do they have urges too? Insects can hardly be attributed complex emotions - more like little robots. They are subject to selection, with no need for urges.
When a person gives nature human-like qualities it always seems to upset some people. Consider that the people that are most concerned at our poor treatment of environment probably do so in part because they see nature as an extension of themselves and give nature human-like emotions despite knowing it's definitely not "real".
The purpose of educators and writers giving animals etc. human qualities is intentional - it makes people more focused and concerned about losing nature and preventing the possible collapse of the environment's food chains, not about intentionally miseducating the public.

No, its all a game of dice and happenstance.
