5 Ιουλ 2016 · It is not one phase of becoming human that represents a major transition, but the cumulative effect of them, the processes of mosaic evolution, and the very recent extinction of all other hominins that enhances the distinctiveness of humans.
With mosaic evolution, a major morphological and behavioural transition of a trait (for instance, bipedalism in hominins) can occur through several adaptive solutions in different species and even genera, each being a different combination of primitive and derived sub-traits.
Mosaic type 1: hominin morphological instability. Mosaic evolution is a pervasive pattern that has characterized, in general, the evolutionary patterns of several groups of organisms through-out Earth’s history (Hopkins & Lidgard, 2012).
These new fossils, dates, analyses, and interpretations lead to confirmation and refinement of the mosaic scheme of human evolution as proposed by early evolutionists such as Lamarck, Haeckel, and Darwin.
Mosaic evolution results from multiple influences molding morphological traits and implies the hierarchical organization of organismal traits into semiautonomous subsets, or modules, which reflect differential genetic and developmental origins.
