Answers. 1  Camels have wide feet to support their weight on the sand. This is an evolutionary trait. The physics behind it goes that that larger the area (beneath the feet), the lower the pressure upon the sand. So, if you have an object exerting 10N of force through a cylinder of 1 m^2, you will have 10 Pa of pressure applied. If the cylinder had 1/2 of the area, it would be 20N. Now, there is an amount of pressure that the sand can support before shear collapsing (sinking). The camels evolved to have wider feet to reduce the pressure exerted on the sand.
