i personally guess every(!) living creature can develop schizophrenic behaviour (not behaving as compared to average) (to me it is just specific/conspicious behaviour (to me it is also normal for that particular individual showing it) especially if there is no physical damage to the brain or in general a developed physical malformation in the brain in the latter cases you may call it abnormal sick and sometimes also call it schizophrene - humans need only to "diagnose" it in humans ....
and i bet if it has to be even an individual only perceiveing/processing 50% (call them humans who obey almost in complete the system-actually the majority-) of happening in the surround can develop schizophrenic behaviour if put in a targetted fit environment - to me animals show a similarity if caught in the wild and put in a cage - on contrary: if you take a gnu out of flock and let it land in gnu-heaven for a specific time and send it back to the flock again others probably will not accept it and diagnose it unacceptable by abnormal behavior compared to us even if the special gnu is just a little smarter by now and brought special supportive machinery to support itself from gnu-heaven to not depend on others while not in gnu heaven ....
animals/insects too must be classified kind of schizophrenic on this planet by humans if humans would be petty but there is no need as they are not integrated in the system - in this system only humans live - as humankind has generated this system (sure it helped humans as a specific creature on this planet alot ) and classified for themselves only in a social way what is normal and what is abnormal and mostly by use of phantasies or wacky theories or ethics (another phantasy to me) in general , etz- if you look at this system from an outside logic view you may find this system (even to me as human it appears almost in 100% abnormal) very sick - so human as a social entity shall not wonder if 1% turns out to be different in a special way from the other 99% even if they are called schizophrenic - are scientist who pursue bigbang, blackholes, etz. classified sick? no - not in general - they pursue topics/phantasies which are mostly accepted by the environment (even if just for entertainment) and this scientists can make a living out of this .... is a priest classified sick? not either by the public in general... but for example the individual which conquers mindwise the universe by abusing god is classified sick as she/he tries to put things right for her/his brain which never can be put right ... the individual just has a certain drive towards projected theories or topics .... on this planet is not much having profound evidence ... human kind is not that intelligent thats the reason its brain developed phantasy (i do agree humankind has alot of phantasy and that makes it kind of very intelligent again) to cope with topics which at stage of evolution are out of reach by far just to cope with the environment they built or they are born into - if you build a sick environment/system and obey or not obey the system .... in both cases you depend on it ...
