In 1997 the landmark Ouhakanaku v. the State of Georgia case ended with the supreme court ruling that forbidding inter-species adoption violated the bill of rights, which itself was amended in 1987 to recognize all species as deserving the same rights and liberties.
Over the following 19 years, studies comparing the physical and mental well-being of inter-species adopted children have consistently found them at rates comparable to their intra-species adopted peers.
Ouhakanaku v. the State of Georgia
Recognized as the first case of inter-species adoption, Sigsikapa Ouhakanuku (a naturalized Gimelian citizen of the United States) Was denied the right to adopt her human partner of three years’ children by her county clerk which lead to the world famous lawsuit of Ouhakanaku v. the State of Georgia which went all the way to the supreme court and ended with the ban on adoption based on one’s species to be unconstitutional in a 7-2 ruling.
Human — Venusian
Adoptions between humans and Venusians are extremely rare in both ways, not only due to the biochemical barrier between species make cohabitation difficult but also due to the vastly different upbringing of the species. Human parents are generally ill-equipped to deal with a child requiring 20 or more hours a day of constant stimulation while Venusians find the human children’s lack of autonomy difficult to compensate for.
Human — Gimelian
Most common of inter species adoptions, human and Gimelians are closely related enough that parenting and child progression is very similar with only minor differences (such as Gimelians’ vegetarian diet) added with the species sexual compatibility often leading to mixed couples.
Human — Itharii
Although Itharii have only fairly recently settled on earth aleph, there are already many cases of Itharii adopting human children due to the Itharii cultural norms placing heavy emphasis on children’s welfare. However the same cultural norms lead to the virtual nonexistence of parent-less Itharii as orphans are quickly taken in by relatives or friends of the family.
