biogenesis




The production of substances, biological structures, or new organisms by existing life-forms; more particularly, the principle that all living organisms derive from parents generally similar to themselves. This long-held principle was originally established in opposition to the idea of spontaneous generation of life. On the whole, it still holds good, despite variations in individuals caused by mutations, hybridization, and other genetic effects. Compare with abiogenesis.
