Aging and resultant death appear to be universal features of life on our planet. It was once thought that simple organisms might live indefinitely, or at least escape the demise we see so clearly in higher organisms, but recent careful tests have shown that even single-celled microbes such as bacteria age and die (Stewart et al. 2005). They display increased probability or risk of mortality with time (under essentially unchanging conditions), which is a common phenomenological definition of aging. At present, it appears that individuals of every species that has been investigated with sufficient rigor will decline and experience increased mortality risk over time.1
