A mini-review of the evolutionary theories of aging

چکیده

This article reviews some studies testing evolutionary theories of aging and shows that they are not always confirmed. Nevertheless, many gerontologists consider now that these theories provide a general explanation of the aging process. In such conditions, we may wonder whether time has come to provisionally accept these theories in order to redirect the research efforts of gerontologists towards other directions, such as the search for new means to modulate the aging process. 1 Laboratoire d'Éthologie et de Psychologie Animale, E.R.S.
