No, not all people have exactly the same number of bones. While most adults have 206 bones, this number can vary for several reasons.
Firstly, infants are born with approximately 270 bones. As they grow, some of these bones fuse together, resulting in the 206 bones typical of adult skeletons. For example, the bones in the skull and the spine fuse as a person ages.
Additionally, there can be variations from person to person due to congenital conditions, such as extra ribs or additional carpal bones in the hands. These anatomical differences can lead to some individuals having a slightly different bone count.
In conclusion, while 206 bones is the standard count for adults, the exact number of bones can differ among individuals based on age and genetic variations.
