Systems thinking has largely developed as a field of inquiry and practice in the 20th century, and has multiple origins in disciplines as varied as biology, anthropology, physics, psychology, mathematics, management, and computer science.
Furthermore, the tentative placement of disciform Kaschgaria and discoid Stilnolepis sister to the entire subtribe suggests that there may have been multiple origins for disciform, as well as discoid capitula.
Hence, multiple origins occur, as in third row of Figure 8.
GBM is derived from multiple origins, such as glial cells and/or NSCs that have undergone neoplastic transformation.
This lack of evidence is a major limitation, since plasma GAGs may have multiple origins, such as from broken or damaged tissues with high connective content.
A much more accurate understanding of the actual taxonomic distribution of DUI combined with a taxonomically expanded version of our robustly supported bivalve phylogeny would allow a rigorous evaluation of the single vs. multiple origins of DUI hypotheses as well as the rates of DUI gain vs. loss.
Besser compared to conspecific diploids using microsatellites, and suggested that introgression as well as multiple origins of the tetraploids might have contributed to the tetraploid diversity.
All Our Variant Futures: From Workprint to Final Cut (2007, 29 minutes), produced by Paul Prischman, appears on the Blade Runner Ultimate Collector's Edition and provides an overview of the film's multiple versions and their origins, as well as detailing the seven-year-long restoration, enhancement and remastering process behind The Final Cut.
The gGCSI can be used to suggest the type of replication machinery used, i.e., bi-directional replication from a single origin and replication from multiple origins in eubacteria and archaea, as well as RCR in plasmids.
Despite multiple origins of myofibroblasts as revealed by recent studies (LeBleu et al., 2013; Falke et al., 2015), the critical roles of macrophages in the formation and activation of myofibroblasts in renal fibrogenesis have been consensually appreciated (Vernon et al., 2010; Nikolic-Paterson et al., 2014).
