Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.

Founder effect is most likely for a particular human population with a higher incidence of polydactyly (extra fingers/toes) than the human population as a whole.
In population genetics, the basic effect is the loss of genetic variation that occurs when a new population is founded by a very small number of individuals from a larger population. As a result of the loss of genetic variation, the new population may differ significantly, both genotypically and phenotypically, from the parent population from which it originates. In extreme cases, the founder effect is thought to lead to speciation and the subsequent evolution of new species The founder effect is a form of genetic drift. This is a phenomenon in which a new population is derived from a small isolated group of individuals. The new population is genetically different from the parent populations. The founder effect can arise from cultural isolation. For example, the Amish population in the United States exhibits a founder effect because it grew from very few founders, they do not have any newcomers, and tends to marry within the same community.
