Sure, it's not optimal long-term planning. Evolution doesn't plan ahead at all, its only super power in that regard is being very slow and gradual. If species A gets better and better at eating the abundant species B, and this continues for a million years and species A specializes and evolves to be unable to eat anything else, and the population of A increases to a point where B's population suddenly plummets, they could both go extinct. But usually A doesn't get that effective at killing B (before the crisis), and what happens is a repeating population cycle, the old boom and bust.

Weirdly, Olaus Magnus (Big Olaf) was involved in this one as well, the same person who did the map in the article.
