Daly of Harvard University published his authoritative paper ''“Meteorites and an Earth model,”'' where he studied the analogies between terrestrial rocks and [[meteor]]ites, coupled with deductions on the probable nature of the Earth’s interior. He hypothesized that the latter ones originated by disruption of a planet once situated between Mars and Jupiter, in the region now occupied by [[asteroid]]s. At first textbooks have quoted his theory approvingly, but later it has been disfavored due to mineralogical discontinuities between different groups of meteorites which were interpreted as evidence against a single parent body hypothesis. Nevertheless, the meteorites, “enigmatic bodies,” have managed to attract the great resurgence of interest in scientific research.<ref>{{cite journal |title=Meteorites |author=Brian Mason|journal=American Scientist |volume=55| issue=4 |year=1967|url=http://www.jstor.org/stable/27837038?seq=1#page_scan_tab_contents}}</ref> | + | In 1943 R.A.
