In principle, natural genetic variation may also affect the global molecular buffering of morphological traits, which would be detected by differences in phenotypic potentials among natural strains.
Furthermore, it has been suggested [ 15, 16] that future studies should be focused more clearly on the possible differences in natural selection caused by island characters (size and isolation) [ 17], ecological mechanisms (e.g. predation rate and inter/intraspecific competition) [ 18] and species specific mechanisms (e.g. evolutionary constraints caused by additive genetic variation).
In particular, infiltrating ductal (IDC) and lobular carcinomas (ILC) (the most frequently observed varieties of invasive breast cancer, accounting for 70 75% and 10 14% of all invasive tumours, respectively) are characterised by differences in their histological structures and natural history (Harris et al, 1992).
There are still wide regional differences in natural gas prices, with North America by far the least expensive, Asia highest and Europe in the middle.
Divergent natural selection caused by differences in solar exposure has resulted in distinctive variations in skin color between human populations.
We have shown that host preference is controlled by differences in body odour profiles of different individuals, with non-attractive people producing natural "repellents" [ 4].
Differences between natural and artificial walls were detected, but these were confounded by differences in size between wall types.
Rural conflicts have tended to focus on access to natural resource while urban conflicts have tended to be triggered by differences in ethnicity, religion, indigeneity and partisan politics.
Thus, the action of natural selection, or more appropriately the effect of removing selection, is only revealed by differences in the local structure of the coexpression networks.
