Concept:Development is a continuous, predictable process guided by universal principles. One key principle is that the rate of growth is not uniform across different stages of life.
Explanation:Development is a lifelong process from conception to death, so it is not short-term. Hence, option A is incorrect.
Individual differences exist because of the interaction of heredity and environment (e.g., nutrition, opportunities). Therefore, option B is false.
Development is predictable: for instance, bone X-rays can forecast height. So option D is false.
The rate of development is not uniform: rapid changes occur in early childhood, a slower phase follows, then a sudden spurt during adolescence, and finally it slows again. This uneven rate means development is not uniform across all stages. Thus, only option C is true.
Answer:C. Development is not uniform in all the developmental stages
