Adoptive immunity acts in a host after their immunological components are withdrawn, their immunological activity is modified extracorporeally, and then reinfused into the same host. [ 1 ] [ 2 ] This process in its former part is analogous to adoption: a child is once adopted out from their home, grown up, and then returned to their home of birth.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...

A 2004 study found that after gaining a child (whether through birth or adoption), respondents reported less depressed affect, more disagreements with their spouse, and more support from their own parents, but it appeared the experience of becoming an adoptive parent or a stepparent was less stressful than the adjustment to biological parenthood.

The first adoption study on schizophrenia published in 1966 by Leonard Heston demonstrated that the biological children of parents with schizophrenia were just as likely to develop schizophrenia whether they were reared by their parents or adopted [5] and was essential in establishing schizophrenia as being largely genetic instead of being a result of child rearing methods.
Additionally, both types of studies depend on particular assumptions, such as the equal environments assumption in the case of twin studies, and the lack of pre-adoptive effects in the case of adoption studies. Since the definition of "nature" in this context is tied to "heritability", the definition of "nurture" has consequently become very ...
