The same laws and rules are valid for radioactive natural and artificial isotopes.
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
Lack of a selection factor. In the absence of selection pressure from natural, sexual or artificial sources, the propagation of random genes would increase. Mutation rates may also be tuned to optimise genetic drift (emphasis on may!).
The main difference to remember is that natural selection is a nonrandom process while genetic drift is a random process.
The non-random survival of randomly varying replicators. According to Richard Dawkins.
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
No. Natural selection is the non-random survival of randomly varying replicators. The random variation part could be thought of as mutation and recombination that the non-randompart, natural selection, works with.
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.

Random processes are not part of the theory of evolution by natural selection. Excepting random genetic mutation that provides the variation natural selection works on.
