how do animals without parental training know how to be the animals they are?

Question

Like snakes, bees, lizards, crocs. Everything that doesn’t have a parent raise them. How do they “know” how to survive?

Answer 1

I work with a number of animals, and hand reared many. My response to this is that an animal has a set of behaviours, names ‘innate’ or ‘instinctive’ behaviours. These are almost programmed when they are born and do this without learning. An example of this is the choking response to cough, or the baby’s behaviour to suckle when breastfed. It helps us survive to a stage where we can learn.
