Answer:
There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult. The reason for the variability in the number of bones is because some humans may have a varying number of ribs, vertebrae, and digits.
The human skeleton of an adult consists of around 207 to 213 bones, and there are 300 bones in children, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process).
