The gradual formation or production of organs or parts by a process of evolution or development, as when the seed develops the root and the stem, the initial stem develops the leaf, branches, and flower buds; or in animal life, when the germ evolves the digestive and other organs and members, or when the animals as they advance in organization acquire special organs for specific purposes.
The supposed act or tendency in being of every kind, whether organic or inorganic, to assume or produce a more complex structure or functions.
The ultimate reason of things must lie in a necessary substance, in which the differentiation of the changes only exists eminently as in their source; and this is what we call God. Gottfried Leibniz
I went to boarding school in the country, so there's no real differentiation between family and friends. I went there from when I was 8 until I was 17 - it was insane. If you earn my friendship, you are my family, and I'll do anything for you. Jamie Campbell Bower
There have only been about a half dozen genuinely important events in the four-billion-year saga of life on Earth: single-celled life, multicelled life, differentiation into plants and animals, movement of animals from water to land, and the advent of mammals and consciousness. Elon Musk
America has believed that in differentiation, not in uniformity, lies the path of progress. It acted on this belief; it has advanced human happiness, and it has prospered. Louis D. Brandeis
Progress is measured by the degree of differentiation within a society. Herbert Read
