Bipedal creature found on Earth. First creature in the biosphere to succesfully refine abstract thought into more than the ability to lie and/or delude itself, humans developed the technique of picturing the way things might be and then planning ways to make reality fit the pattern.
This faculty turns in upon itself, however, when the attempt fails, leading to such emotional conflicts as self-loathing, bias against more succesful others, self-worship, or sublimation of individualism into a group mind.
Humans have borrowed many traits from other species such as hunting for pleasure ( from cats and squids ), enslaving other species ( from ants ), protecting and nurturing other species to gather products from them ( from ants ), spoiling other creatures habitats by their own constructs ( from beavers ), and creating and sharing habitats with other creatures ( from corals, rodents and birds ). Humans have invented several concepts for themselves, such as artistic endevour for its own sake, resource gathering and stockpiling for its own sake, ignorance and self-delusion as a natural right, love and attraction not solely for the purpose of reproduction, worship of the different, lack of diversity as a positive, and worship of the identical.
Humans are capable of percieving that they are less than what they imagine themselves to be. This is not only their major problem, it is also their major strength.
" Some say modern humans are smarter than cavemen, some say we are less. I think we are exactly as smart as cavemen, and that is pretty smart indeed".
