A scan of the Origin for occurrences of perfect finds that Darwin used it to describe structural complexity, specialisation and competitiveness in the struggle for existence - arguably fair use for a general audience in 1859, and utterly distinct from its sense in Bonnet, much less Bonaventure.
In GBIF, the origin of an occurrence can be specified using a controlled vocabulary in the 'basisOfRecord' field.
Pleistocene glacial events could be at the origin of the occurrence of allopatric phases for several populations of this species.
In the baker's yeast Saccharomyces cerevisiae they are at the origin of the occurrence, maintenance, transmission in a non-mendelian manner and propagation of 3 traits, the [URE3], [PSI+] and [PIN+] phenotypes [2] [4].
In order to select the most effective methods to reduce steam deficit, it is important to detect the origins of its occurrence.
Previous work on the origin and mode of occurrence of mineral matter in the Late Permian coals from eastern Yunnan includes that of Chen et al. (1992), Dai and Chou (2007), Dai et al. (2008, 2014), and Wang et al. (2012, 2013).
In this paper, we present new data on the abundances, origin, and mode of occurrence of minerals in coal from two cores, the "NYa" and "NYb" holes drilled through the Longtan and Changxing Formations in the Niuchang-Yigu mining area, Zhenxiong County, northeastern Yunnan.
Because either could have been produced by recombination subsequent to the origin of C11, their occasional occurrence is not informative.
The identification of this mutation provided a biochemical and physiological explanation for the origin of PSS and the occurrence of PSE meat in pigs.
A detailed investigation of the pedigree data of resistant varieties that is reported in Additional file 10 allowed us to hypothesize the origin of resistance and its occurrence in other cultivars characterized by common ancestors.
Finally, on the basis of the massive CTX-M-1 predominance in animals in our study compared to its relatively low frequency in healthy humans, further investigational efforts into the origin of the unexplained high occurrence of CTX-M-15 in the human population are warrented.
