Today, however, the tendency is to suppose a vertical uplift of the crystalline rock and a sliding down (under the effects of both gravity and the relatively plastic nature of the layers of schists and marls) of the sedimentary cover, and a somewhat more complicated origin for the nappes.
Approval of our proposal on the origin of cultivated banana clones through one or more backcrosses would fill an important gap in the history of humankind, tropical agriculture in particular, provide an argument to support the concept of a more complicated origin of clonal crops and, last but not least, call for reconsideration of strategies used in the current banana improvement programmes.
The degree of asymmetry varied widely among individuals and, while both lefty and righty individuals were clearly present, the distribution of jaw laterality was unimodal, suggesting that this textbook antisymmetric trait has a more complicated developmental origin.
If the Broadway musical "Hamilton" has shown us anything, it is that our national symbols are always more complicated than their origin myths.
However, the differential diagnosis of intrascrotal tumor in older patients might be more complicated, because the origin of the testicular or paratesticular might sometimes unclear.
On December 10th five different regulatory agencies approved the Volcker rule; it will come into force, awkwardly enough, on April 1st.During the three years between its conception and birth, the rule has grown into something much bigger and more complicated than its origins would have suggested.
The observation of both kinds of imprinted genes in placenta (Proudhon and Bourc'his, 2010; Wang et al., 2011) and a more complicated picture of parental origin-specific expression in seeds (Autran et al., 2011; McKeown et al., 2011) do not argue against the coadaptation theory.
However, in regard to rotatory instability, ACL lesions, and the pivot-shift test, we should remember that the pivot-shift test assesses rotatory instability, and in particular, according to Hughston [19], the antero-lateral instability, whose origin is more complicated than a simple result of ACL lesion.
It now seems unlikely that the presence of anthocyanins is the primitive character in the order, however, and that there exists a more complicated evolutionary history of the origins of betalains and anthocyanins.
Cosans states that while "Owen agreed that evolution occurs, he argued that it occurs by more complicated means than those outlined in the Origin" (pg. xix).
Therefore, reconstructing the overall phylogeny of domestic dogs is considerably more complicated as a result of the recent origin of many breeds coupled with high levels of admixture during breed formation.
