Contemporary scientists hold that human physical variations, especially in those traits that are normally used to classify people racially skin colour, hair texture, facial features, and to some extent bodily structure must be understood in terms of evolutionary processes and the long-range adaptation of human groups to differing environments.
Body structure and the amount of body fat have also been explained by evolutionists in terms of human adaptation to differing environments.
It has also been experimentally shown that the crossing of genotypes adapted to differing environments can negatively impact growth (Tymchuk et al. 2007).
We cannot discard, however, the possibility that some or all of these genes have an excess of fixed polymorphisms in the cultivated tomato lineage due to a population bottleneck during domestication [ 39], or because of the effect of natural selection due to differing environments.
Taoist philosophers, such as Zhuangzi in the 4th century BCE, also expressed ideas related to evolution, such as denying the fixity of biological species and speculating that species had developed differing attributes in response to differing environments.
According to Joseph Needham, Taoism explicitly denies the fixity of biological species and Taoist philosophers speculated that species had developed differing attributes in response to differing environments.
These morphological differences are likely to constitute adaptations to differing environments.
The huge number of organisms with the specific structures and functions they have developed during evolution in adaptation to differing environments represents the basis for all biomimetic R&D-projects.
Among conifers Douglas fir is considered closely adapted to differing environments and regression models between canonical variates and climate resulted in R values of 0.50 and 0.68 (St. Clair et al. 2005).
These studies are used to identify differentially expressed transcripts with respect to measured variables of interest, such as differing environments, treatments, phenotypes, or clinical outcomes, and for the identification of expression quantitative trait loci (eQTL), i.e. genomic regions whose genotype is correlated with the RNA expression in a panel of genetically diverse individuals [ 1].
