Sociogenomics
Sociogenomics, also known as social genomics, is the field of research that examines why and how different social factors and processes (e.g., social stress, conflict, isolation, attachment, etc.) affect the activity of the genome. Social genomics as a field is very young (< 20 years old) and was spurred by the scientific understanding that the expression of genes to their gene products, though not the DNA sequence itself, is affected by the external environment. Social genomics researchers have thus examined the role of social factors (e.g. isolation, rejection) on the expression of individual genes, or more commonly, clusters of many genes (i.e. gene profiles, or gene programs).

History

In the early 2000s, initial work on this topic was conducted in animal model systems, such as ,

Zebra Finch
The zebra finches are two species of estrildid finch in the genus ''Taeniopygia'' found in Australia and Indonesia. They are seed-eaters that travel in large flocks. The species are: Previously, both species were classified as a single species, the zebra finch (''T. guttata''). However, they were split by the IUCN Red List and BirdLife International in 2016. The International Ornithological Congress followed suit in 2022 based on studies noting differences in plumage, mtDNA divergence, and assortative mating between both species in captivity. The zebra finch was first captured in 1801 during Nicolas Baudin's expedition to Australia. The Indonesian species was described in 1817 by Louis Jean Pierre Vieillot in his ''Nouveau Dictionnaire d'Histoire Naturelle'', where he gave it the scientific name ''Fringilla guttata''. The Australian species was then described in 1837 by John Gould as ''Amadina castanotis''. Its current genus, ''Taeniopygia'', was described in 1862 by Ludwig R ...
