| 词条 | biogenetic law |
| 释义 | biogenetic law biology also called Recapitulation Theory, postulation, by Ernst Haeckel (Haeckel, Ernst) in 1866, that ontogeny recapitulates phylogeny—i.e., the development of the animal embryo and young traces the evolutionary development of the species. The theory was influential and much-popularized earlier but has been of little significance in elucidating either evolution or embryonic growth. |
