Darwin only had one theory of evolution, and he defined it in his book On The Origin of Species.
Charles Darwin proposed the Theory of Evolution or Natural Selection. The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
In 1838, Theodor Schwann and Matthias Schleiden were enjoying after-dinner coffee and talking about their studies on cells. It has been suggested that when Schwann heard Schleiden describe plant cells with nuclei, he was struck by the similarity of these plant cells to cells he had observed in animal tissues. The two scientists went immediately to Schwann's lab to look at his slides. Schwann published his book on animal and plant cells (Schwann 1839) the next year, a treatise devoid of acknowledgments of anyone else's contribution, including that of Schleiden (1838). He summarized his observations into three conclusions about cells:The cell is the unit of structure, physiology, and organization in living things.The cell retains a dual existence as a distinct entity and a building block in the construction of organisms.Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).We know today that the first two tenets are correct, but the third is clearly wrong. The correct interpretation of cell formation by division was finally promoted by others and formally enunciated in Rudolph Virchow's powerful dictum, Omnis cellula e cellula...: "All cells only arise from pre-existing cells".The modern tenets of the Cell Theory include:All known living things are made up of cells.The cell is structural & functional unit of all living things.All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).Cells contains hereditary information which is passed from cell to cell during cell division.All cells are basically the same in chemical composition.All energy flow (metabolism & biochemistry) of life occurs within cells.
Information on the theory of evolution can be found in the original book on the theorem of evolution by natural selection, the brainchild of Charles Darwin, called "On the origin of species".
Darwin worked on his book most of 1859 and it was published 24 November, 1859.The Theory Of Evolution By Means Of Natural Selection, Or The Preservation Of Favored Races In The Struggle For Life.Of course Charles Darwin had been working on this theory more than twenty years before his book was published. He and Wallace both had papers submitted and read in 1858.

Things with no cells are basically all non-living things. Some examples can be- Book Pen Phone Computer Paper You get the idea right? Just remember the cell theory by Theodor Schwann, Matthias Schleiden, and Rudolf Virchow. It states that.... All living things or organisms are made of cells and their products. New cells are created by old cells dividing into two. Cells are the basic building units of life. So all living things have cells while technically, most non-living things don't. I hope this helped!
Thomas Hobbes is credited with creating the philosophies that most western political systems are now based off of. He wrote the book Leviathan on social contact theory in 1651.
