Sea Urchins as a Model of Negligible Senescence Species that exhibit negligible senescence tend to be long-lived, but more interestingly appear to exhibit few to none of the functional declines of degenerative aging until very late in life, quite unlike the situation for most mammals, and particularly for humans. One can argue that the most useful species that exhibit negligible senescence are those with near relative species that age more normally. The closer the relative, the more likely it is that comparing the biochemistry of the two will lead to new knowledge regarding aging. So naked mole rats versus other, less long-lived mole rats, Brandt's bat versus other shorter-lived small bats, or as in today's open access paper, the red sea urchin versus short-lived urchin species. Whether this work on the comparative biology […]
