Hare "wanted to know if dogs' powerful rapport with humans was a quality that the original domesticators of the dog had selected for, or whether it had just come along with the tameness, as implied by Belyaev's hypothesis". At present, a Florida-based company called the Lester Kalmanson Agency Inc imports foxes for those who want to keep them as pets. The study of plate tectonics is done by structural geologists. Foxes dig out dens to provide a safe underground space that is mostly used for raising fox cubs, also called kits.
