Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.

Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Mutation, genetic drift, gene flow and the driver of adaptive change, natural selection.
Is genetic drift of product of genetic change?
Genetic drift is a product of random sampling. Like all forms of sampling or selection, variation within the sample set is required. Thus for genetic drift to occur genetic change (mutation) is required. However, it would be an error to call genetic drift a product of genetic change.
Would evolution stop if there were no natural selection?
No, but adaptive change would be difficult. Remember, evolution is the change in allele frequency over time in a population of organisms. Mutation, genetic drift, genetic flow and other processes would continue without natural selection.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
What is the similarity between natural selection and genetic drift?
No. Genetic mutations lead to changes in the gene. This results in a (possible) new allele. Genetic drift is the change in frequency of an allele in the population due to chance. The smaller the population the bigger the chance on genetic drift (like it is more likely to coin flip 10 heads in a row then 1000 heads) while on the other hand the bigger the population the bigger the chance new alleles will be created by mutations.

In evolution is genetic drift adaptive maladaptive both or neither?
my notes from my class say maladaptive....
What small genetic change such as a single mutation may result in?
genetic drift....

A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
What is the Random change in a populations allele frequency is known?
Random change in allele frequency is called genetic drift.
Would evolution stop if there were no natural selection?
No, but adaptive change would be difficult. Remember, evolution is the change in allele frequency over time in a population of organisms. Mutation, genetic drift, genetic flow and other processes would continue without natural selection.
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
What is the term for changes in allele frequency that that happen randomly from one generation to the next?
Genetic drift
Species drift to form a new species?
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
