Well, let's break down what you just said. Would chasing them with helicopter and airplanes do anything to help them evolve their sense of smell?No.Would traps or snares?Maybe,but you said yourself in an aerlier post,apples and oranges when using cover scent.So again,no.Would poison only kill the ones with a poor sense of smell?No.The little pop up blasters,would they only kill the ones with poor sense of smell?No.There are too many variables to consider here.I personally think they are just a little smarter when it comes to things that threaten them.Some animals don't remember the things that can get them into trouble.A muskrat is a good example.They get away at one bait set,only to get caught in the next.They survive by having lots of offspring.Coyotes do the same,actually.I read somewhere that when there is an abundance of food,coyote litters tend to be bigger.This has nothing to do with it's sense of hearing.So maybe this is what happened in Texas.As the predator population decreased,the prey increased.The surviving coyotes would be smarter and have larger litters.The things learned about poison,traps etc. would be passed on to the pups.But nothing here tells me that their sense of smell got better.
