biogenetic (adj.)

1870, "science or doctrine of biogenesis; history of organic evolution;" see bio- + -geny. As "history of the evolution of organisms, genesis or evolution of matter manifesting life (including ontogeny and phylogeny)," 1879.

Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).

In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.

also bio-genesis, 1870, "theory that living organisms arise only from the agency of pre-existing living organisms" (as opposed to spontaneous generation), coined by English biologist T.H. Huxley from Greek bios "life" (from PIE root *gwei- "to live") + -genesis "birth, origin, creation." A word from the Darwin debates. The meaning "the theoretical evolution of living matter from complex inanimate chemicals" is from 1960. Compare also biogeny. Related: Biogenic; biogenetic; biogenetical.
