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.
5 Ιουλ 2016 · The pattern of hominin evolution described here fits this higher level form of mosaic evolution. The transitions described relate to the different elements of human evolution—ranging behaviour and energetics, foraging and diet, reproduction and life history, and cognition and behavioural transmission ( figure 7 ).
Abstract. Mosaic evolution, whereby transitional forms display a mixture of primitive and derived features, is nowadays recognized as a ubiquitous pattern of macroevolutionary change. Less known is that this expression was coined by Gavin de Beer in 1954.
26 Δεκ 2017 · Here, we analyze mosaic evolution in the avian skull using high-dimensional 3D surface morphometric data across a broad phylogenetic sample encompassing nearly all extant families. We find that the avian cranium is highly modular, consisting of seven independently evolving anatomical regions.
14 Μαΐ 2018 · mosaic evolution. views 3,611,240 updated May 08 2018. mosaic evolution Differential rates of development of various adaptive attributes within the same evolutionary lineage. For example, a particular taxon might show greatly different rates of change with respect to the head, body, and limbs.
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.
10 Νοε 2021 · The mosaic brain evolution hypothesis, stating that brain regions can evolve relatively independently during cognitive evolution, is an important idea to understand how brains evolve with potential implications even for human brain evolution.
