Well, evolution doesn't guarantee that your instincts will ensure your escape from danger, it does giuarantee that your species has the means to detect it. Those individuals who get caught by predators would have been aware of the danger, even if too late, like all the others who escaped from it would have been.
There are individual differences. A percentage of the population is born with some defect (blind, deaf, etc.), and thus more likely to perish or be killed by predators. With thusly defective entities, it is difficult or impossible to judge whether they are equipped with the species-specific instincts not.
And you believe that dogs should know as you do, that cars are dangerous. And horses should know the noise a bucket makes isn't dangerous, and nor is the bucket. You aren't anthropomorphising. O. K.
Because when dogs get hit by cars, this is utter anthropomorphizing rocket science, yes.
Whose definitions, though? Which ones do we "abide by"?
That depends on what one knows and what one wishes to accomplish in each interpersonal interaction.
