If so, the researchers suggested that human and canine jealousy might exist for similar "primordial" reasons.
Therefore, unlike Johnson et al., we did not observe replenishment of the primordial follicle pool; the reason for the discrepancy between our study and that of Johnson et al. [25] remains to be determined.
The reason is that the primordial germ cells of a heterozygous mother contain one copy of the mutant POLG allele and this could cause accumulation of a small amount of mtDNA mutations during their proliferation and maturation into oocytes.
The results of the current study and recent reports suggest that the deregulation of signaling events in oocytes such as Tsc/mTORC1 signaling, PTEN/PI3K signaling (8, 9) and the p27-Cdk system (33), may also be the reasons for the defects in primordial follicle development in humans, which can result in pathological conditions of the ovary, including POF and infertility.
The reason is that there is no primordial helium in the atmosphere; due to the small mass of the atom, helium cannot be retained by the Earth's gravitational field.
But a recent talk by Marc Rayman, chief engineer for NASA's Dawn mission, impressed me with the many other reasons to be interested in these primordial rocks.
But there is good reason to pay attention to such a primordial conflict between two athletes.
Yet from worrying about the magazine's priority, in any chronological sense (and by taking Bickerton's claims as both his guide and straw man), he misses the reasons for the enduring preëminence of the primordial Cahiers of the nineteen-fifties.
Primordial transit sequences evolved with a phenylalanine for two reasons; at first this amino acid attenuates the interaction with the cyanelle surface containing mono- and digalactosyldiacylglycerol.
It is the core reason our progenitors wandered forth from the first primordial valleys in search of more room, better hunting or more fertile soil.
