Biogeneesiin

Biogeneesiin is the Finnish term for biogenesis, the process by which living organisms arise from pre-existing life. In biology, biogenesis refers to the generation of new cells or organisms through reproduction and developmental processes. It contrasts with abiogenesis, the study of how life originally originated from non-living matter. The concept is supported by the cell theory, notably Virchow’s dictum omnis cellula e cellula, which states that every cell arises from a pre-existing cell.

Biogenesis occurs through various mechanisms. In multicellular organisms, reproduction can be sexual or asexual; fertilization followed by embryogenesis produces a new individual, while mitotic cell division drives growth and tissue renewal. In unicellular organisms, reproduction is typically by binary fission, budding, or fragmentation. Embryogenesis, organogenesis, and tissue differentiation are developmental stages that illustrate biogenesis at higher organizational levels.

Modern biology emphasizes genetic heredity and molecular replication as the basis of biogenesis: DNA replication, transcription, and translation enable the propagation of life and the expression of traits across generations. While biogenesis explains propagation of existing life, abiogenesis concerns how the first life-form emerged on early Earth under prebiotic conditions; the two concepts address different questions in the history of life.

In Finnish scientific writing, biogeneesi is the standard term, and the inflected form biogeneesiin can appear in sentences describing processes related to biogenesis.
