In the years following Louis Pasteur's 1859 experiment, the term "spontaneous generation" fell increasingly out of favor. Experimentalists used a variety of terms for the study of the origin of life from nonliving materials. "Heterogenesis" was applied to the generation of living things from once-living organic matter (such as boiled broths), and Henry Charlton Bastian proposed the term "archebiosis" for life originating from inorganic materials. Disliking the randomness and unpredictability implied by the term "'spontaneous' generation," in 1870 Bastian coined the term "biogenesis" to refer to the formation of life from nonliving matter. Soon thereafter, however, English biologist Thomas Henry Huxley proposed the term "abiogenesis" to refer to this same process and adopted "biogenesis" for the process by which life arises from existing life; it is this latter set of definitions that became dominant.
