Why Do Babies Have More Bones Than Adults?

The video explains why babies have more bones than adults, highlighting that babies are born with around 300 bones, while adults have 206. This difference is due to the presence of cartilage, which gradually turns into bone through endochondral ossification. As babies grow, many small bone segments fuse to form single bones, reducing the total count. The video also discusses the soft spot on a baby's head and other fascinating bone facts, such as the hyoid bone, the femur, and the stapes. It concludes with insights into bone growth and density changes throughout life.
