The SNPs found to be associated with metal levels in this study may not be the biological cause of association but rather in LD with causative variants; hence, it may be interesting to further investigate this possibility through deep sequencing in associated LD blocks.
Moreover, biologists are not in agreement about the existence of an inherent biological cause for aging.
This groundbreaking study provides the most robust evidence to date that stress itself is unlikely to be a biological cause of the disease.
We understand the biological cause of excess body-weight gain: too many calories consumed and too few calories expended.

Like Dhurandhar and Atkinson, Bloom suspects that obesity has a biological cause — but rather than turning to gut microflora or adenovirus infection for an explanation, he is partial to what he calls "the lazy-greedy gene" hypothesis, his slightly disparaging shorthand for what is more generally known as the thrifty genotype.
In Matthias's case, doctors have been unable to pin it down the biological cause.
