Arms and Front Legs The arms of humans have a much different skeletal setup compared with the legs. Describe the movement of the warmer and colder air masses in a WARM front. Very similar to ours but for some reason cats decided to walk and run on their toes or the end of the metacarpus. 3. Cats, dogs, horses and cattle are able to crossbreed but birds, fish and reptiles seemingly cannot. People who study anatomy define these structures as a body part of one species that closely resembles that of another.

A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. If you have two equal size objects, the one with the higher density would weigh more. 11. The hypothesis stands that if two structures have similar morphology but are used for different purposes, both organisms have evolved from the same origin, or are derived from a common ancestor. The carpus is the wrist as far as I am concerned. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats.
