Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.
As you may know, some of the stereotyped behaviors exhibited by autistic children are also found in zoo animals who are raised in a barren environment.

Independence is all very well, but we animals never allow our friends to make fools of themselves beyond a certain limit; and that limit you've reached.

Biology will relate every human gene to the genes of other animals and bacteria, to this great chain of being.
The human young must learn to perceive these affordances, in some degree at least, but the young of some animals do not have time to learn the ones that are crucial for survival.
