According to the KQED video "Science on the SPOT: Lupe the Mammoth Comes to Life", how can you tell the biological age of a mammoth (how old it was when it died, NOT the age of its fossils)?

Unique question.well, using science, you cannot create or destroy even if you do eat yourself so you would not grow twice as big, nor would you disappear. you would stay the same but change states potentially, or at least change your appearance (obviously).hope this . keep up these unique questions.

Answer cratons

Settlement patterns, river navigation, numerous natural harbors.
