Theropod and gang.
your just wrong again about these things.
Animals are all afraid of man in the wilderness. It is not from personal contact. I suggest it needs to be provoked by something like confidence or some impression or something But not defeat by violence. They don't internalize genetically incidents. I repeat excellent nature shows and zillions of acounts of man and beast in Canada all show that all creatures flee the appearance of man. Even bells or waving arms keeps bears away. They flee nothing else but a human noise will save hikers.
This is a well known fact and usually the case is made that animals learned to fear man and it somehow sticks like the way they fear poisoness coloured snakes etc.
Polar bears are not shot away but are scared away by flares, or druming garbage cans up there. They simply get used to people like any animal but a little agression sends them flying. They would never fly from a animals.
Polar bears are scared to the point of white hair.

The author of Genesis knew his audience , which lived with lions and bears, would know a child could scare them off.
