ISSN 1645-6564. 1 (2002) 71-87.1645-6564http://hdl.handle.net/10284/1898Panspermia, an ancient theory implying the dispersal of life throughout the universe, was revived in its modern form by Fred Hoyle and the present author in a series of publications over the period 1977 to 2001. Although unpopular at first, it is now slowly gaining support and is coming to be discussed as a serious scientific possibility among theories of the origin of life. A summary will be given of the modern scientific case of panspermia, indicating that astronomical, geological and biological evidence is converging towards its support.engPanspermiaCometsMeteoritesMicrofossilsInterstellar matterOrigins of lifelecture
