Editing Adoption (section)

===Parenting===
The biological relationship between a parent and child is important, and the separation of the two has led to concerns about adoption. The traditional view of adoptive parenting received empirical support from a [[Princeton University]] study of 6,000 adoptive, step, and foster families in the United States and South Africa from 1968 to 1985; the study indicated that food expenditures in households with mothers of non-biological children (when controlled for income, household size, hours worked, age, etc.) were significantly less for adoptees, step-children, and foster children, causing the researchers to speculate that people are less interested in sustaining the genetic lines of others.<ref>{{Cite journal| last1 = Case | first1 = A.| last2 = Lin | first2 = I.

Raynor, The Adopted Child Comes of Age, 1980</ref>

Other studies provide evidence that adoptive relationships can form along other lines. A study evaluating the level of parental investment indicates strength in adoptive families, suggesting that parents who adopt invest more time in their children than other parents, and concludes "...adoptive parents enrich their children's lives to compensate for the lack of biological ties and the extra challenges of adoption."<ref>{{cite web |last=Hamilton |first=Laura |title=Adoptive Parents, Adoptive Parents: Evaluating the Importance of Biological Ties for Parental Investment|work=American Sociological Review |url=http://www.asanet.org/galleries/default-file/Feb07ASRAdoption.pdf |access-date=3 June 2007 |archive-url = https://web.archive.org/web/20070221194844/http://www.asanet.org/galleries/default-file/Feb07ASRAdoption.pdf |archive-date = 21 February 2007}}</ref> Another recent study found that adoptive families invested more heavily in their adopted children, for example, by providing further education and financial support. Noting that adoptees seemed to be more likely to experience problems such as drug addiction, the study speculated that adoptive parents might invest more in adoptees not because they favor them, but because they are more likely than genetic children to need the help.<ref>{{Cite journal| last1 = Gibson | first1 = K.| title = Differential parental investment in families with both adopted and genetic children| journal = [[Evolution and Human Behavior]]| volume = 30| issue = 3| pages = 184–189| year = 2009| doi = 10.1016/j.evolhumbehav.2009.01.001| bibcode = 2009EHumB..30..184G}}</ref>

Psychologists' findings regarding the importance of early mother-infant bonding created some concern about whether parents who adopt older infants or toddlers after birth have missed some crucial period for the child's development. However, research on [[The Mental and Social Life of Babies]] suggested that the "parent-infant system", rather than a bond between biologically related individuals, is an evolved fit between innate behavior patterns of all human infants and equally evolved responses of human adults to those infant behaviors. Thus nature "ensures some initial flexibility with respect to the particular adults who take on the parental role."<ref>{{cite book|last=Kaye|first=K|title=The Mental and Social Life of Babies|year=1982|publisher=Univ.

Beyond the foundational issues, the unique questions posed for adoptive parents are varied. They include how to respond to stereotypes, answering questions about heritage, and how best to maintain connections with biological kin when in an open adoption.<ref>A. Adesman and C. Adamec, Parenting Your Adopted Child, 2004</ref> One author suggests a common question adoptive parents have is: "Will we love the child even though he/she is not our biological child?"<ref>Michaels, Ruth, and Florence Rondell. The Adoption Family Book I: You and Your Child. Page 4.</ref> A specific concern for many parents is accommodating an adoptee in the classroom.<ref>{{cite web |url=http://www.adoptionfilm.com/video.html |title=Adoptionfilm.org &#124; Messages from the Production Team |access-date=2006-03-12 |url-status=dead |archive-url=https://web.archive.org/web/20051231133955/http://www.adoptionfilm.com/video.html |archive-date=31 December 2005}} Adoption: An American Revolution</ref> Familiar lessons like "draw your [[family tree]]" or "trace your eye color back through your parents and grandparents to see where your genes come from" could be hurtful to children who were adopted and do not know this biological information.

Concerning developmental milestones, studies from the Colorado Adoption Project examined [[Heritability|genetic influences]] on adoptee maturation, concluding that cognitive abilities of adoptees reflect those of their adoptive parents in early childhood but show little similarity by adolescence, resembling instead those of their biological parents and to the same extent as peers in non-adoptive families.<ref name="Nature 1997">{{cite journal | last1 = Plomin | first1 = R. | last2 = Fulker | first2 = D.W. | last3 = Corley | first3 = R. | last4 = DeFries | first4 = J.C. | year = 1997 | title = Nature, nurture, and cognitive development from 1–16 years: A parent-offspring adoption study | journal = Psychological Science | volume = 8 | issue = 6| pages = 442–447 | doi=10.1111/j.1467-9280.1997.tb00458.x| s2cid = 145627094 }}</ref>

Similar mechanisms appear to be at work in the physical development of adoptees. Danish and American researchers conducting studies on the genetic contribution to [[body mass index]] found correlations between an adoptee's weight class and his biological parents' BMI while finding no relationship with the adoptive family environment. Moreover, about one-half of inter-individual differences were due to individual non-shared influences.<ref name="The New England Journal of Medicine">[[Albert Stunkard|AJ Stunkard]], An adoption study of human obesity, [http://content.nejm.org/cgi/content/abstract/314/4/193 The New England Journal of Medicine] {{Webarchive|url=https://web.archive.org/web/20090304013739/http://content.nejm.org/cgi/content/abstract/314/4/193 |date=4 March 2009 }} Volume 314:193–198, 23 January 1986</ref><ref name="International journal of obesity">Vogler, G.P., Influences of genes and shared family environment on adult body mass index assessed in an adoption study by a comprehensive path model, [http://cat.inist.fr/?aModele=afficheN&cpsidt=3406929 International journal of obesity], 1995, vol. 19, no1, pp. 40–45</ref>

These differences in development appear to play out in the way young adoptees deal with major life events. In the case of parental divorce, adoptees have been found to respond differently from children who have not been adopted. While the general population experienced more behavioral problems, substance use, lower school achievement, and impaired social competence after parental divorce, the adoptee population appeared to be unaffected in terms of their outside relationships, specifically in their school or social abilities.<ref name="American Psychological Association">Thomas O'Conner, Are Associations Between Parental Divorce and Children's Adjustment Genetically Mediated?, [http://www.apa.org/journals/features/dev364429.pdf American Psychological Association] 2000, Vol. 36 No.4 429–437</ref>

Recent research has shown that adoptive parenting may have impacts on adoptive children, it has been shown that warm adoptive parenting reduces internalizing and externalizing problems of the adoptive children over time.<ref name="Paine">{{cite journal |author1=Amy L.
