Darwin\'s book was praised by Unitarians as well as by liberal Anglican theologians whose "Essays and Reviews" (1860) sparked considerably more religious controversy in Britain than Darwin\'s publication, as its support of higher criticism questioned the historical accuracy of literal interpretations of the Bible and added declarations that miracles were irrational.', 'Vestiges of the Natural History of Creation" remained a best-seller, and paved the way for widespread interest in the theory of natural selection as introduced and published by English naturalist Charles Darwin in his 1859 book,']}}]}, {'provenance': [{'wikipedia_id': '29932', 'title': 'On the Origin of Species', 'section': 'Section::::Abstract.', 'start_paragraph_id': 1, 'end_paragraph_id': 1, 'meta': {'evidence_span': ['On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.', 'On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin\'s book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the "Beagle" expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.', 'Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.']}}]}]
