Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct

What affect do humans have on animal speciation?
Aside from artificial selection humans are a large part of all other organisms environments. So, any barriers humans erect could bring about allopactric speciation, though I can not think of any specific examples there. Also, human caused extinctions can cause adaptive radiation of a species into the niche of a species driven extinct by humans.
What is the relationship between humans and extinctions?
human activities appear to have eliminated two or three species per decade, about double the naturalextinction rate.
