Look at the age of fossilized bones, look at DNA evidence and all the other mountains of evidence about the LONG - TERM DYNAMICS of LIVING ORGANISMS on this planet over the span of BILLIONS of years.

Specimens of that species may be up to 100,000 years of age, e.g., see the 2012 article «Portuguese scientists discover world's oldest living organism» at theportugalnews.com/news/view/1152-20 or see the February 2012 paper, «Implications of Extreme Life Span in Clonal Organisms: Millenary Clones in Meadows of the Threatened Seagrass Posidonia oceanica» on which the news article was based, which is available online at the PLOS ONE website at plosone.org/article/info:doi/10.1371/journal.pone.0030454.

The cosmic tide may at one time have seemed to be immobilized, lost in the vast reservoir of living forms; but through the ages the level of consciousness was steadily rising behind the barrier, until finally, by means of the human brain (the most «centro - complex» organism yet achieved to our knowledge in the universe) there has occurred, at a first ending of time, the breaking of the dykes, followed by what is now in progress, the flooding of Thought over the entire surface of the biosphere.

This method would also enable them to follow potential aging processes that occur in blood stem cells in detail as they occur naturally in a living organism.

Studies of the organisms that lived there — and may still — will provide insight into life during the ice ages and on other planets, scientists say.

«A new model organism for aging research: The short - lived African killifish.»

The fruit fly Drosophila melanogaster has a life expectancy of approx. 8 weeks and belongs to the model organisms studied by scientists at the Max Planck Institute for Biology of Ageing in their quest to understand aging in living beings.

Yeast is just one of the organisms, including mice, dogs and nematodes, for which caloric restriction seems to slow aging and prolong life.

Finch's ideas about senescence from his grad school days have also held up: The popularity of the Hayflick model has declined as other research questioned its relevance to aging in whole organisms, and recent studies in long - lived nematodes have confirmed Finch's hunch that brain hormones control aging (see Johnson Review).

With the marine fossils grouped by age, the collection shows a dramatic 65 - 70 % reduction in the number of species living in the Antarctic 66 million years ago — coinciding exactly with the time when the dinosaurs and many other groups of organisms worldwide became extinct at the end of the Cretaceous Period.

An obvious question is how cellular senescence caused by deficient DNA repair finally affects the aging of a living organism.

The point is subtle, however: if aging is damage, there are many ways to generate cell and tissue damage in a living organism that have no particular relevance to aging, even though they also result in disability and death.

To see if those effects might explain the link between paraquat, aging, and PD in living organisms, the team turned to genetically altered mice that the Campisi lab had developed for senescent cell studies.

Aging itself is a system - wide movement towards chemical equilibrium (away from the highly regulated far - from - equilibrium state) and as such is an imbalance from which all living organisms suffer.

Interspecies comparison and the introduction of specific genetic changes in short - and long - lived model organisms are used to delineate genetic factors influencing the aging process.

Numerous subsequent studies have confirmed that a calorie restriction of 30 to 60 percent of ad libitum intake increases the life span by similar amounts in a range of organisms including yeast, roundworms and rodents, while simultaneously decreasing or delaying the occurrence of age related diseases such as numerous cancers (including lymphomas, breast and prostate cancers), hypertension, stroke, diabetes, nephropathy, autoimmune disorders and other risks factors for cardiovascular disease (3,4).

Radiocarbon dating is a method that provides objective age estimates for carbon - based materials that originated from living organisms.

Evolution theory plays a critical role in the why issue because it attempts to explain why each living organism has its particular design and therefore why different species display different aging characteristics and different life spa...
