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.
Mosaic evolution, the occurrence, within a given population of organisms, of different rates of evolutionary change in various body structures and functions. An example can be seen in the patterns of development of the different elephant species.
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.
development of this concept – loosely defined as a range of different habitat types, such as. woodlands, riverine forest and savannah within a limited spatial area– in studies of human. evolution in the last sixty years or so. We outline the key developments that took place.
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.
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.
