It is filled with imperfections and developmental variation.
The differences are due not only to natural developmental variation.
To determine whether their behaviour is a developmental variation or pathological depends on the child's age, the frequency and intensity of the behaviour, and the overall environment.
An empirical understanding of normal developmental variation in the amygdala is emerging.
Malformed vertebrae can arise secondary to errors of vertebral formation, fusion and/or segmentation and developmental variation.
Conclusion: Increased maternal prenatal stress seems to be one of the determinants of temperamental and developmental variation of infants.
Together, these findings underscore the complexity of bone adaptation and highlight functional and developmental variation in determinants of skull form.
Lysozyme activity of the non-immunized S. exigua had developmental variation, with the highest level in the fifth instar larvae.
A theory is developed which posits that normal developmental variation in amygdala volumes may be altered under conditions of severe stress.
Developmental variation in activity levels was observed and indicates that developmental stage should be an important consideration in future analyses of Mormon cricket movement.
Moreover, many conclusions are compromised by a lack of matched RT and sequence datasets, the filtering out of developmental variation in RT, and the use of somatic cell lines to make inferences about germline evolution.
