Описание: Excerpt from Present Problems in Evolution and Heredity The reversional tendency is hereditary. There are many cases, both of reversions (as in the teeth) and indefinite variations being hereditary, that is, reappearing in several generations, or skipping a generation and recurring in the second. Summary - 13mm are clearly marked out several regions in the human body in which evolution is relatively most rapid, such as the lower portion of the chest, the upper cervicals, the shoulder girdle in its rela tion to the trunk, the lower portion of the arm and hand, the outer portion of the foot. We notice that these regions especially are centers of adaptation to new habits of life in which new organs and new rela tions of parts are being acquired and old organs abandoned. We observe also that all parts of the body are not equally variable, but these centers of evolution are also the chief centers of variability. The variations here are not exclusively, but mainly, of one kind; they rise from the constant struggle between adaptation and the force of heredity. Here is a muscle like the extensor indicis attempting to give up an old function and establish a new one; it maintains its new func tion for several generations, and then goes back without any warning to a function which it had thousands of years ago. Thus the force of reversion strikes us as a universal factor. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
