Vitamin D deficiency prevails in epidemic proportions all over the Indian subcontinent, with a
prevalence of 70%–100% in the general population. In India, widely consumed food items …

Researchers from diverse backgrounds are converging on the view that human evolution
has been shaped by gene–culture interactions. Theoretical biologists have used population …

Organisms, through their metabolism, their activities, and their choices, define, partly create,
and partly destroy their own niches. We refer to these phenomena as" niche construction." …

In this Analysis we use published 16S ribosomal RNA gene sequences to compare the
bacterial assemblages that are associated with humans and other mammals, metazoa and …

A SNP in the gene encoding lactase (LCT)(C/T-13910) is associated with the ability to digest
milk as adults (lactase persistence) in Europeans, but the genetic basis of lactase …

In most human populations, the ability to digest lactose contained in milk usually disappears
in childhood, but in European-derived populations, lactase activity frequently persists into …

Comparative studies of ethnically diverse human populations, particularly in Africa, are
important for reconstructing human evolutionary history and for understanding the genetic …

Lactase persistence (LP) is common among people of European ancestry, but with the
exception of some African, Middle Eastern and southern Asian groups, is rare or absent …

A key step toward the discovery of a gene related to a trait is the finding of an association
between the trait and one or more haplotypes. Haplotype analyses can also provide critical …

Identifying genomic regions that have been targets of natural selection remains one of the
most important and challenging areas of research in genetics. To this end, we report an …
