The morphological variability among early Pleistocene forms can be attributed to evolutionary processes or most likely multiple Bison invasions at that time.
These nonrandom extinctions have been attributed to evolutionary causes that determine the patterns of rarity across taxonomic groups of different sizes, and to critical aspects of species' life history that constrain their abundance and distribution.
SSs are known to contain complex interdependencies between nonadjacent positions that could be attributed to evolutionary pressure from very complex biological splicing machinery.
This difference may be attributed to evolutionary differences, similarly to caveolin-1, the deletion of which is only lethal in zebrafish, but not in mice (38).
Most of the homozygous SNVs in the Vero cell line were attributed to evolutionary divergence between the genus Macaca and Chlorocebus, which was ∼8 12 million years ago.
The still remaining considerable gap in participation could be attributed to evolutionary differences in the sense that men still have a greater training motivation than women [ 38].
The question addressed in this review is whether this evidence can be attributed to evolutionary changes in response to the documented selection forces, or whether it results from individual plasticity, that is, the capacity of individuals to adjust their phenology according to environmental cues informative about lower and/or higher trophic level phenology.
To clarify what patterns have been observed, we undertook a specific review of the literature that detected phenotypic responses to climate change in wild fish populations, with a particular interest in the extent to which these responses could be attributed to evolutionary or plastic processes.
However, demonstrating that an avian phenological trait is heritable and is under directional selection only suggests that there is potential for adaptive evolution, but is insufficient to conclude that an advance of the average population laying date or arrival date from migration can be attributed to evolutionary adaptation (e.g. Teplitsky et al. 2010).
Diversity of domain combinations and evolution of domain superfamilies has been attributed to evolutionary processes such as gene recombination, gene duplication, gene fusion and fission, loss of fragments at the terminal region, alternative splicing, etc., creating complexity in the proteomes of higher eukaryotes including human [ 4, 9- 13].
