Random Chance
Random changes.This would be called genetic drift.
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.
genetic drift may occur when a small group of individuals colonizes a new habitat
Blood groups are affected by genetic drift randomly, making it special.
No, genetic drift is an example of microevolution.

Random Chance
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 change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
Random changes.This would be called genetic drift.
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.
The English Peppered Moth is a result of natural selection, not random genetic drift. This moth evolved because of the light colors of lichens on trees in their habitats.
