People do have the erroneous idea that somehow natural selection, genetic drift, migration and other "evolutionary processes" could lead to evolution, and the fact is that they do not, they work against the possibility of evolution.
This is a huge problem for evolution if you ask me.
If this were acknowledged, if students weren't made to absorb this erroneous idea, we could go on to the next topic which is the only genetically additive process, mutation.
Have evos ever gone about to quantify the effects of the first set of factors with observed rates of mutation, one wonders?
