PGE – Product Generation Engineering describes that new products are developed based on reference products by three types of variation: carryover variation, embodiment variation and principle variation, where the two latter ones together form the share of new development.
In principle, variation in diversity across loci could also be due to selection at linked genes (Maynard Smith and Haigh 1974; Charlesworth et al. 1993; Barton 2000), rather than variable mutation rates.
The curriculum explored plant reproduction and genetic principles, highlighting variation in heirloom tomato fruits to reinforce the concept of the genetic basis of phenotypic variation.
Embracing the constraints and principles of variation, environment, evolution, and ecology.
Making use of these inductive frameworks, Darwin restructured our understanding of life based on the first principles of variation, survival, and reproduction to generate his theory of evolution by natural selection.
Using in silico evolution, we can apply the principles of variation and natural selection to a mathematical model, and evolve "organisms" with parameters that are particularly good at solving a set task (e.g. to minimize the noise of protein expression).
In the physical variational principle the variations of the electric potential and magnetic potential are divided into local variations and migratory variations.
While these are the general principles, important variations are possible.
However, Brown states that the principle of variation was very much a part of Russian musical thought and creativity.
In principle, this variation of cell supply could be achieved by two alternative mechanisms.
