The Theory of Evolution promotes the idea that the strongest living organisms adapt to their surroundings and survive.
Charles Darwin's theory of evolution.survival of the fittest
The scientific theory behind cell theory is that it explains the fundamental properties of all cells. The cell is the basic unit of all living organisms.
Because he studied organisms very closely and propounded the theory of evolution with the phrase 'Struggle for existence and survival of the fittest organisms'.
If by "why" you mean "what," a well tested framework that explains a wide range of observations in science is called a theory.
Each individual cell needs energy and oxygen to survive, just as living things do. Cellular respiration explains why living organisms need oxygen and energy, and exactly where those resources go.
cell theory
Natural selection is part of the scientific theory of evolution. What occurs is that in a population of a certain species, there will be variations. Some variations will help organisms survive better than other. Nature "selects" those traits that help organisms survive. Thus, animals with better adaptations survive longer and reproduce more so that eventually, those adaptive traits become more widespread.
He was around before the theory. So there is no way to know.
Cell theory is one of many subdivisions of scientific theory. Therefore, since cell theory IS scientific theory, I don't see how you can compare them. This is like saying compare mammals to squirrels.
there is a variation in every population and organisms compete for limited resources and organisms produce more offsprings that can survive,organisms pass through genetics traits on to the offsprings .
there are more organisms in the environment than can possibly survive. This sets up a struggle to survive. The organism that are beat-suited to the environment will survive and reproduce. :)
