The embryonic stage lasts approximately 4 week(s), beginning at conception. Details about stages of development can be found below.
<h3>What are the stages of development?</h3>
The stages of development of a human is summarized into four stages as follows:
- Embryonic stage
- Germinal stage
- Fetal stage
In the embryonic stage of development, which occurs after conception, the baby is called an embryo. Embryonic stage lasts 4 weeks.
During the embryonic stage, the cells of the embryo (called embryonic stem cells) multiply and develop. They become the hundreds of different types of cells needed to make a whole human body.

Nature vs Nurture debate.
Explanation:
Development in human is inborn.The stages of development is dictated and directed by expression of genes encoded by the DNA.Therefore physiological and biochemical interpretations of these DNA dictates is known as human development. it is a fixed mechanisms which is fastest at childhood,and progressively slower at advanced stage.<u>Although environmental factors may influence this developmental stages, the exact mechanism of occurrence is constant and fixed.</u>
<u />
Nuture concept believe that, human development is as a result of societal and cultural factors in the environment, and the progression of the development is due to the influences of theses factors on human perception of life. Thus Human development is acquired through life exposure and experiences.They are therefore dynamic, and not static, but fluctuates based on level of exposure in the environment.
<u>However, both concept interacts with one another to ensure an holistic human development. Generally it is the interaction of the environment with genetic that explains the concept of natural selection and evolution of human race. </u>
