Hey cool cats, I’m Dr. Universe, here to answer your baffling science questions like this one. How do bones form? Most humans have 206 bones. But did you know, you are actually born with about 300? Before you were born, your skeleton was soft and bendy. Then when you were a baby, some of those bones started to fuse together to become bigger bones. Meanwhile, cells in your body were helping make your bones even stronger. We all have bone-eating cells and bone-building cells that work in a big cycle. Since the day you were born, your skeleton has been in a way always remaking itself. Send me a science question of your own at askdruniverse.wsu.edu.
