Human predation doesn't apply the same positive evolutionary pressures as apex predators. Typically predators eat the slowest, weakest, dumbest prey. Humans either target the biggest, strongest prey (if hunting individuals) or indiscriminately massacre a swathe of the ecosystem (eg. dragnet fishing).
- srtjstjsj 6y agoWhat is a "positive evolutionary pressure"? Why are fast, smart, strong fish important?
- wizzwizz4 6y agoI'd imagine smart fish survive better in general; we're changing the environment, and brains can adapt faster than evolution. Fast, strong fish are better sources of muscle, which is what we hunt them for.
- cma 6y agoDon't other apex predators hunt for size as well? And aren't whales similar in some ways to dragnet fishing? They don't target the weakest straggler sardines or the injured phytoplankton only.
