Maturity (geology), in petroleum geology; Maturation, as a threat to internal validity of an experiment; Tissue maturation, an aspect of developmental biology The final stages of cellular differentiation of cells, tissues, or organs
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [1]
Biologically, an adult is a human or other organism that has reached sexual maturity. In human context, the term adult has additional meanings associated with social and legal concepts. In contrast to a legal minor , a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and ...
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
The theory was developed in the 1950s [4] and is used to answer questions about topics such as organism size, age of maturation, number of offspring, life span, and many others. [5] In order to study these topics, life history strategies must be identified, and then models are constructed to study their effects.
While maturity is often termed as a label awarded to a child, research has revealed that children themselves hold a clear sense of their own autonomy and personal jurisdiction. For instance, American elementary-aged school children demonstrated an acknowledgement of the limits of their parents' authority over their choice of dress, hairstyle ...
Some tortoises show negligible senescence. Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age.

Haldane mirrors Gould's hypothesis by stating a "major evolutionary trend in human beings" is "greater prolongation of childhood and retardation of maturity." [ 3 ] Delbert D. Thiessen said that "neoteny becomes more apparent as early primates evolved into later forms" and that primates have been "evolving toward flat face."
