Cosmic Ancestry is a new theory pertaining to evolution and the origin of life on Earth. It holds that life on Earth was seeded from space, and that life's evolution to higher forms depends on genetic programs that come from space. (It accepts the Darwinian account of evolution that does not require new genetic programs.) It is a wholly scientific, testable theory for which evidence is accumulating.
The first point, which deals with the origin of life on Earth, is known as panspermia — literally, "seeds everywhere." Its earliest recorded advocate was the Greek philosopher Anaxagoras, who influenced Socrates. However, Aristotle's theory of spontaneous generation came to be preferred by science for more than two thousand years. Then on April 9, 1864, French chemist Louis Pasteur reported his experiment disproving spontaneous generation as it was then held to occur. In the 1870s, British physicist Lord Kelvin and German physicist Hermann von Helmholtz reinforced Pasteur and argued that life could come from space. And in the first decade of the 1900s, Swedish chemist and Nobel laureate Svante Arrhenius theorized that bacterial spores, propelled through space by light pressure, were the seeds of life on Earth.
Starting in the 1970s, British astronomers Fred Hoyle and Chandra Wickramasinghe rekindled interest in panspermia. By careful spectroscopic observation and analysis of light from distant stars they found new evidence, traces of life, in the intervening dust. They also proposed that comets, which are largely made of water-ice, carry bacterial life across galaxies and protect it from radiation damage along the way. One aspect of this research program, that interstellar dust and comets contain organic compounds, has been pursued by others as well. It is now widely accepted that space contains the "ingredients" of life. This development could be the first hint of a huge paradigm shift. But mainstream science has not accepted the hard core of modern panspermia, that whole cells seeded life on Earth.
