In DARWIN'S ''Origin of Species'' of 1859 and in other writings there
are numerous empirical observations and instinct explanations of anima
l behaviour. Thorough analysis shows that DARWIN'S behavioural data ar
e often interpreted psychologically as ''expression'', ''conciousness'
', and ''intelligence''. Basic instincts according to DARWIN are gener
ated by custom behaviour and genetically acquired properties. This is
a neo-Larmarckian explanations. DARWIN therefore may not be regarded a
s the founder of ethology.
