Understanding Bones in Babies and Adults

The video explains why babies have more bones than adults, starting with the fact that babies are born with around 270 bones, which decrease to 206 in adulthood. This is due to the presence of cartilage in babies, which is softer and more flexible than bone. As babies grow, cartilage is replaced by bone through a process called endochondral ossification, leading to bone fusion. The video highlights signs of this process, such as the soft spot on a baby's head, and concludes by encouraging viewers to subscribe for more content.
