Why arre thigh bones big and finger bones small?

Answer 1

Thigh bones, or femurs, are larger and stronger to support the weight of the body and withstand the forces generated during activities like walking and running. In contrast, finger bones are smaller and more delicate because they primarily serve to provide dexterity and perform fine motor tasks, requiring less strength and support. The size difference is a result of evolutionary adaptations to the specific functions each type of bone serves.
