Does genetic drift lead to evolution?
Yes. Genetic drift-- the change in allelic frequencies of a population due to chance-- can play a major role in evolution. The effects of drift are most pronounced in small, isolated populations. Drift can bring alleles to fixation very quickly in such populations, and can lead to genetic differentiation between them, possibly contributing to speciation.
What are the basic driving forces behind evolution?
the driving forces behind evolution are Mutation, Natural Selection, Gene flow, and Genetic drift So lets start with Natural selection, all this means is that that individuals best suited for their environment are more likely to survive and reproduce. That's all it is, Individuals with certain inherited traits leave more off spring than others. an example of natural selection would be anti-biotic resistance in bacteria. Now mutations, Mutations are random and can be beneficial, neutral, or harmful to an organism, however not all mutations matter in evolution. only those that can be passed on to the next generation matter. Those that occur in somatic cells do not matter to evolution. Genetic drift - change in the gene pool of a small population due to chance. an example. Disasters such as the BP oil spill occur which kills off a large number of individuals, this results in a drastic reduction of the population size which in turn affects the genetic variation. and finally Gene flow which is when individuals migrate between populations, this brings in more genetic variation.
Storing genetic information is a major function of?
nucleic acids
Which major change can occur in a small population that is the result of genetic drift?
One problem is that the population will loose it genetic variation. With little genetic variation a population is less likely to have some individuals that will be able to adapt to a changing environment.
What are the five mini theories of the Theory of Evolution?
There are five major points to Darwin's theory of evolution. These are: 1)members have heritable variations; 2)in a population, more individuals are produced than can survive; 3)some individuals will adapt to better survive; 4)an increasing number of individuals will have adaptations due to genetic inheritance; and 5)natural selection results in a population that is adapted to the environment.
When is genetic drift a major factor evolution?

How might genetic drift alter the diversity of a population?
Genetic drift basically is the reduction of genetic diversity where certain genes are selected through random chance. Founder or bottleneck events are the major ones. Those certain genes may or may not be beneficial.
