Editing Archaeogenetics (section)

==== Domestication of plants ====
The combination of genetics and archeological findings have been used to trace the earliest signs of plant [[Domestication of plants|domestication]] around the world. However, since the nuclear, mitochondrial, and chloroplast [[genome]]s used to trace domestication's moment of origin have evolved at different rates, its use to trace [[genealogy]] have been somewhat problematic.<ref name=":15" /> [[Nuclear DNA]] in specific is used over [[Mitochondrial DNA|mitochondrial]] and [[chloroplast DNA]] because of its faster mutation rate as well as its intraspecific variation due to a higher consistency of [[Polymorphism (biology)|polymorphism]] [[genetic marker]]s.<ref name=":15" /> Findings in crop 'domestication genes' (traits that were specifically selected for or against) include
* tb1 (teosinte branched1) – affecting the [[apical dominance]] in maize<ref name=":15" />
* tga1 (teosinte glume architecture1) – making maize kernels compatible for the convenience of humans <ref name=":15" />
* te1 (Terminal ear1) – affecting the weight of kernels<ref name=":15" />
* fw2.2 – affecting the weight in tomatoes<ref name=":15" />
* BoCal – [[inflorescence]] of broccoli and cauliflower<ref name=":15" />
Through the study of archaeogenetics in plant domestication, signs of the first global economy can also be uncovered. The geographical distribution of new crops highly selected in one region found in another where it would have not originally been introduced serve as evidence of a trading network for the production and consumption of readily available resources.<ref name=":15">{{Cite journal|last=Zeder, Emshwiller, Smith, Bradley|date=March 2006|title=Documenting domestication: the intersection of genetics and archaeology|url=https://anthropology.si.edu/archaeobio/images/zederetal_2006_docdom_tig.pdf|journal=Trends in Genetics|volume=22|issue=3|pages=139–146|via=Science Direct|doi=10.1016/j.tig.2006.01.007|pmid=16458995}}</ref>
