Darwin's most famous work was properly titled On the Origin of Species, not (as cited in Yeoman's article) On the Origin of the Species. Adding that extra word makes it sound as if Darwin's focus was on "the" species, in this case referring to modern humans. Darwin's work had more to do with finches than people, and he was trying to show the mechanism of speciation over time, not necessarily that humans came from a specific progenitor.
It's just one word, but dropping that small word misleads people about the focus of Darwin's work. Understanding natural selection is not about proving or disproving the existence of God or the origin of the universe. It's not even necessarily about the origin of humankind, no matter what "the" press tells us.
