Sentence examples for most ancient origin from inspiring English sources

If this is correct, the CD genome would include components of the four diploid genomes comprising the section Oryza of genus Oryza (A, B, C and E); the C genome, for which the Asian origin and the ecological adaptation to wet forests suggest its most ancient origin among the section Oryza [19] appears to be the pivotal genome.

Using multiple sets of empirical evidence and rigorous statistical methodologies, we reject the conclusion of a recent origin of unisexual Ambystoma and support the hypothesis that unisexual Ambystoma is the most ancient lineage in unisexual vertebrates known to exist.

The sub-haplogroup DE*, presumably the most ancient lineage of the D/E haplogroup was only found in Africans from Nigeria [ 2], supporting the "Out of Africa" hypothesis about modern human origin.

While an anthropology undergraduate at the University of California (UC), Berkeley, Bibi took an interest in the search for the most ancient human origins and the study of human bones, volunteering for archaeological fieldwork in Honduras and learning how to analyze vertebrate fossils in the lab of Anthony Barnosky.

We applied this test to the putative wheat DNA and find that these reads are most likely not of ancient origin.

Even though most domains have an ancient origin [ 7], few domain combinations are shared between the three domains of life [ 3, 8].

Moreover, the complete conservation of BOE 17 20 and GFU 29 30 in multiple species studied here and in the rock pigeon (Columba livia, 2n = 80, Columbiformes) as revealed by BOE 17 20 probes [ 20] suggests that these four pairs of dot-shaped microchromosomes have a much more ancient origin, most likely already being present in the ancestral bird karyotype.

The within-clade values are consistent with D xy among species calculated for two nearby loci (D xy = 0.016 0.018, Table 5) and estimated genome-wide gambiae-arabiensis D xy of 0.011 (O'Loughlin et al. 2014), whereas the between-clade values are approximately three-times higher, and even higher than the estimated genome-wide gambiae-merus D xy of 0.0235, most likely reflecting an ancient origin.

The origin of the most ancient clade is estimated to predate the origin of vascular plants (including Selaginella) while the other two clades originated by gene duplication within a seed-plant ancestor before the divergence of angiosperms and gymnosperms.

Generally, our estimate was consistent with previous time estimates of the origin of unisexual Ambystoma [ 5, 20, 21] which validates them as the most ancient unisexual vertebrate lineage known to exist [ 2].

The ancient origin of most Iranian phylogroups has however been recently reinforced by independent data showing they may have retained ancestral morphological features [ 33].
