Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.

The specificity principle of exercise states that, to become an expert in a particular exercise or skill one should perform that exercise or skill. That is, the things that one do during physical activity should be relevant to one desired outcomes, thus, the training regimen must go from general to specific during training.
