Adoption studies that followed have had similar results. [4] "The Stockholm adoption study (2000 adoptees) found that criminality alone was not transmitted from biological parents to adoptees, but did find elevated rates of criminality in adopted-away offspring of biological parents with alcohol use disorders (AUD) alone, or with both AUD and ...
An adoption agency is an organization that supports the legal process of placing children with adoptive families. These agencies work to match pregnant women with individuals or couples who wish to adopt. Adoption agencies can be public (run by government agencies) or private (operated by nonprofit or for-profit organizations).
In biology, competition is an interaction between organisms in which the fitness of one is lowered by the presence of another. This may be because both rely on a limited supply of a resource such as food, water, or territory. [67] Competition may be within or between species, and may be direct or indirect. [68]

From 1945 to 1973, it is estimated that up to 4 million parents in the United States had children placed for adoption, with 2 million during the 1960s alone. [2] Annual numbers for non-relative adoptions increased from an estimated 33,800 in 1951 to a peak of 89,200 in 1970, then quickly declined to an estimated 47,700 in 1975.
The underlying theme of the essay is the need to teach biological evolution in the context of debate about creation and evolution in public education in the United States. [5] The fact that evolution occurs explains the interrelatedness of the various facts of biology, and so makes biology make sense. [6]
Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity.
