Editing Behavior (section)

==== Determination by genetics or the environment ====
Behaviors can be either [[innate]] or learned from the environment, or both, dependent on the organism.<ref>{{Cite web |title=Result List: Behavior innate learned environment: EBSCOhost |url=https://web.p.ebscohost.com/ehost/results?vid=3&sid=b38e88a7-1bf0-407a-83ac-ed2dad8c1a15@redis&bquery=Behavior+innate+learned+environment&bdata=JkF1dGhUeXBlPWlwLHNzbyZkYj1wYmgmY2xpMD1GVCZjbHYwPVkmdHlwZT0wJnNlYXJjaE1vZGU9U3RhbmRhcmQmc2l0ZT1laG9zdC1saXZl |access-date=2024-10-03 |website=web.p.ebscohost.com |language=en}}</ref> The more complex nervous systems (or brains) are, the more influence learning has on behavior. However, even in mammals, a large fraction of behavior is genetically determined. For instance, [[Prairie vole|prairie voles]] tend to be [[Monogamy|monogamous]] while, while [[Eastern meadow vole|meadow voles]] are more [[Promiscuity|promiscuous]], a difference that is strongly determined by a single gene, [[Vasopressin receptor 1A|Avpr1a]], encoding a receptor for the peptide hormone [[Vasopressin]].<ref>{{Cite journal |last=Underwood |first=Emily |date=2020-10-22 |title=Solo stars among the genes |journal=Knowable Magazine |url=https://knowablemagazine.org/content/article/living-world/2020/solo-stars-among-genes |language=en |doi=10.1146/knowable-102120-1|doi-access=free }}</ref>
