With the number of playscript , movies , and religions on the topic , it ’s pretty safe to say that humans are basically obsessed with the idea of immortality . This might be connected to the fact that as we age , we essentially lead off to flow apart . Everything from our skin elasticity to lively organs start to flunk as we produce old . This is lawful for many other animals , but not all of them . Some being are capable to live and reproduce for centuries on oddment with no diminished quality of life-time . How this phenomenon interrelate to overall lifespan is explained by Pb generator Owen Jones from the University of Southern Denmark inNature .
For the study , 46 different specie including 23 vertebrates , 10 invertebrates , 12 plants , and 1 alga were compare . The fertility and mortality formula were try , and formal wiseness say that prospicient experience should lead to senescence ; the strong-arm decline experienced during aging .
The researchers found that there actually was n’t a radio link . The organism that experienced the greatest levels of senescence were n’t any more or less likely to have long lives . Among those that do not parade much senescence , lifespan length was fairly equally split as well .
They did find , however , that mammals experience the most aging with plant on the opposite end , hardly experiencing any ill effects from aging . The birds and invertebrates were equally distributed between the two extremes . Because there is no predictable inter-group communication between life span and senescence , this research challenges current evolutionary theory that state that senescence is to be expected because sure genetic diseases ( like Huntington ’s ) do n’t look until afterwards in life , after the organism has give birthing . This is how potentially injurious alleles and mutations are able to persist over meter and parry natural selection .
Not everyone is convincedthat this inquiry throws a spanner in current theories just yet . The study mostly used science laboratory animals , which do not look the same conflict as wild animals . Without see how these living cycle take berth in the actual surroundings when dealing with issues like predators , disease , and starvation , it is hard to make these conclusions . When using data from field study , the cause of death was not always made clear , which questions the results of the study . The authors of the article defend their conclusion , claiming that organism that had n’t been pretend by senescence would be well able-bodied to avoid those environmental pitfalls .
While this paper does present an interesting perspective that ageing is not experienced equally by all organisms , more research will probably be required before environmental biologists seriously attend at retool existing theories .
