A possible explanation for these observations is that KIR3DL0 has been lost from non-primate genomes.
Milk moves from source to processor and consumer fairly effectively, if not always efficiently, though it is not uncommon for tankers of milk to be lost from non-collection due to poor roads and breakdowns" (Kedrock and Agar 2007, p. 32).
Of course, it is possible that genes were co-opted from other functions and then that all of these genes were lost from non-photosynthetic species like T. roseum.
An alternative possibility is that at least some of these genes had a more ancient evolutionary origin in the Metazoa, but have then been lost from the non-lophotrochozoan taxa for which genomic data is currently available.
NCR3 has undergone lineage specific changes, having been lost from the opossum and non-functional in the mouse but the presence of this gene in the wallaby indicates that it was part of the inflammatory region prior to marsupial/eutherian divergence.
The gene has clearly been lost from rodent genomes [ 27].
This suggests that toxicity as a character was either gained in the toxic strains through independent HGTs or alternatively, is an ancestral trait for these cyanobacteria and was lost from the non-toxic strains.
This ensured that a quantisation axis was maintained throughout the trap volume and atoms would not be lost from the trap through non-adiabatic transitions to untrapped high-field-seeking states.
This suggests that DNA was lost from both genic regions and non-functional regions in A. kamchatica.
A total of 420 CM cases that were not matched with other migraine sufferers and 153 CM cases that were not matched with non-migraineurs were lost from the study.
An estimated 0.001 kg C m−2 yr−1 was lost from logging removals in agricultural ecosystems due to non-pure land pixels.
