It takes surprisingly few generations to evolve traits. If there is a distribution of skittishness and a high pass filter takes away everything under a given limit, you'll get rapid evolution.
As another example, urban populations of animals have evolved to tolerate noise in the span of very few generations.
Giant flightless goose- very tasty!

We have actual evidence that it is a developed instinct. If you’ve ever been to the Galapagos islands, it’s extremely obvious. The sea lions and pelicans casually walk up to the counter at the fish market as if they’re just regulars shopping.
This is not a thing. Species don't require generations to learn to be afraid of other species that hunt them. Species have encountered new species since the beginning of time. If it took 1000 generations to learn such a thing, nothing would have ever made it.
It's not as if there's a shortage of dangerous predators in Australia, even to this day.
Just because an article hand waves an explanation doesn't make it so.
