Astonishing was the recognition of this theory. Even more so was the reference to the life particles, the idea of Arrhenius, the great Swede, of life starting on Earth through the dropping of minute, life spores , propelled through space by the driving power of light and, encountering favourable environment here, developing through the vast ages into man and every other living thing we know. 11
