Your skull says a lot about you and who you were, and is often used by forensic investigators in crime scenes to determine more about the victim when flesh-based DNA samples are not available.
For example, the size and shape of your skull can tell scientists whether you were a male or a female, in addition to what your race is, and even how old you were.
Skulls typically have different features depending on several factors, which include size, shape, suture development, protruding features, feature placement, etc. Even your dental records can help scientists determine exactly who you are from just your skull.
While there are a lot of ways to help tell a story from the skull alone, the science isn't 100% perfect. Just like anything else, it has its caveats because everyone in the world is different and genetics aren't perfect either.
It's crazy to think that from just a skull, scientists can do so much to identify where it came from.
