The explanation for the rare origins is almost certainly because complete resistance with high viability involves multiple mutations (Hastings and Watkins 2006), and so requires a highly unlikely series of mutational events to occur simultaneously.
Some were rare, single-origin beans, others were more familiar blends.
Coco runs chocolate schools, and has tasting evenings where rare, single-origin chocolates are sampled accompanied by a glass of Banyuls dessert wine.
Check your genetic ethnicity results for any unique or rare ancestral origins that might aid in narrowing down your search.
Taking the rare "other" origins (encephalitis, tumors, electric shock) also into account, only a slight trend was found (χ(2) = 4.74, P = 0.09) due to the large variability among other causes.
In humans, endotoxic shocks are rare and sepsis origin is often localized.
Nevertheless, in addition to plant abundance (abundant and rare) and plant origin (native and exotic) we accounted for the proportion of the variance explained by plant functional groups (monocotyledons and dicotyledons).
In the current case, characteristic roentgen imaging findings were suggestive of a GCT; however, the possibility of malignancy could not be completely excluded because of the imaging findings, including PET, and the rare site of origin.
Adult-Onset Still's disease (AOSD) is a rare condition of unknown origin with various presentations and unpredictable outcome.
Only few studies have dealt with the ecology of these creatures and studies focusing on the response of these animals to disturbances of anthropogenic origin are rare.
