The seperate ideas i meant are evolution and the idea that the main difference between humans and animals is our ability of reason. ( im not sure if the latter has an official name, maybe rationalism).
Im trying to question that due to the common ancestor humans and apes have , basically if it is known , at which point did us humans gain "reason" and animals did not. Sorry if its still confused.
The most common notion of of mind is that it "emerged" from a fundamentally innert and insensate material reality. Fundamentally I think this is wrong but then I am a panpsychist (panexperientialism, pansensationism, lots of terms) which means I think mind, reason and ultimately intelligence are fundamental inherent (ontologic) properties of nature.
Even under the materialist emergent theory of mind, however, reason and intelligence can not suddenly "pop" into existence. Evolution would require that such abilities develop slowly over eons in time in stages and degrees and that human reason and human intelligence must have their antecedents in similar (even if more primitive) abilities in other species.
Which brings us to the question, what is mind, and what animals, plants, species or other systems in nature possess it? Not as easy a question as you might hope or think. In any event the notion that only man has reason or intelligence is really not compatible with either a materialist emergent evolutionary theory of mind or with a panpsychist (mind and reason are inherent in nature) position. It is also not compatible with empirical science and observation. It is anthropomorphic (only humans have souls, only humans are "made in the image", only humans are intelligent, only humans have reason) a curious vestige of primitive religion and of dualism.
