experience->a posteriori information->a priori information (based on a posteriori inf)->prediction.
E.g., a lion has one tail, may be in future we should like to see a lion with 2 tails ?
However, it is impractical in terms of evolution (?). Why you need a lion with two tails? Because I live in the savannah where a lot of flies; The second tail would be very useful. Thus, prehistoric artist draws two tails.
Modern artist draws two tails since he is an abstractionist. 500 years later one will say that thanks to genetic engineering in the 21st century a lion with two tails have been created.
