KontinuitätsHypothese

KontinuitätsHypothese is a concept in evolutionary biology that proposes gradual changes accumulating over long periods rather than sudden, drastic evolutionary leaps. It suggests that the evolutionary history of life on Earth is characterized by a continuous process of adaptation and modification within lineages, without significant breaks or periods of rapid diversification followed by extinction. This hypothesis contrasts with punctuated equilibrium, which posits that evolutionary history is dominated by long stasis periods interrupted by short bursts of rapid change. The core idea is that the fossil record, when viewed over vast timescales, reflects a slow and steady transformation of species. Proponents of the KontinuitätsHypothese emphasize the role of microevolutionary processes, such as natural selection and genetic drift, acting consistently over eons to produce the observed diversity of life. While not universally accepted, it remains an influential perspective in evolutionary theory, shaping how scientists interpret paleontological data and reconstruct evolutionary pathways. The evidence for and against this hypothesis is often debated, drawing on fossil discoveries, molecular clock data, and comparative anatomy.
