Dec 19, 2015 at 18:10 | comment | added | user2357112 | @geotheory: That's not memory, that's behavior. | |
Dec 19, 2015 at 16:00 | comment | added | shadowtalker | I'd be curious to see an answer that addresses indirect pressure through habitat change, like what happened with pigeons and highways. | |

Dec 19, 2015 at 13:11 | comment | added | geotheory | I don't think its necessarily very different from cats fearing cucumbers - possibly an inherited fear of snakes. | |
Dec 19, 2015 at 13:02 | comment | added | Will Ness | @geotheory that's not a hereditary memory, that's an acquired trait. | |
Dec 19, 2015 at 9:42 | comment | added | geotheory | How's this hypothesis @user2357112 - the effect of man's overfishing is to catch shoals and individual fish that are easier to catch. Therefore the more reclusive/cautious fish survive, which means those characteristics are passed one. I'd say that would be a reasonable approximation of inherited memory. | |
Dec 19, 2015 at 7:44 | comment | added | user2357112 | Evolution just doesn't work like that. Here, have a link to an explanation of how it does work. | |
Dec 19, 2015 at 7:28 | comment | added | Snazzy Sanoj | No, what I meant was that fish should've developed some sort of hereditary memory that we're one of Predators, atleast when they saw fellow fish being captured by us, and should've learned to tackle the "fish-nets"(or whatever). But, this isn't happening even after 40,000 years. Why? | |
Dec 19, 2015 at 7:11 | comment | added | user2357112 | Pretty much the same reason we don't think the fish are developing psychic powers. There's no evidence for it, the mechanisms by which evolution is known to operate wouldn't produce such a thing, and it wouldn't explain any observed phenomena better than the existing explanations. | |
