The default is to outpace your need. Imagine if we evolved to somehow hunt just enough meat. There’d be some of us with less efficient systems for controlling that behavior that end up starving while they think they are bringing in enough food. Thats no good for reproductive fitness. Overshooting on the other hand is good. Another factor, symbiotic relationships tend take much longer to evolve that carefully balanced relationship between symbiont and symbiont. Parasitic relationships tend to evolve sooner and its also not uncommon the parasite overshoots and kills off its own host.
