The new life begins as a one-cell structure that is created when the sperm and egg merge. The process of embryonic development starts with this cell, called the zygote, which divides to form two cells. This process continues until there are billions of cells in your body! It is amazing to think about how each of these cells has its own DNA, meaning they have different traits from one another; some are good at making you more intelligent while others may be better for digestion.
