Marine organisms with eternal life can solve the riddle of aging

Apr 19, 2011

Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of Gothenburg have shown how colony-forming ascidians (or sea squirts) can activate the enzyme telomerase, which protects DNA. This enzyme is more active also in humans who attain an advanced age.

" that clone themselves, in which part of an individual's body is passes on to the next generations, have particularly interesting conditions related to remaining in good health to persist. This makes it useful to study these animals in order to understand mechanisms of ageing in humans", says Helen Nilsson Sköld of the Department of Marine Ecology, University of Gothenburg.

There are enormous differences in the lengths of life of the Earth's species. Some animals and plants that reproduce asexually can in principle achieve essentially eternal life; there are examples of deep-sea corals that are tens of thousands of years old. Helen Nilsson Sköld has decided to study sea squirts and starfish, which are species whose genes resemble closely those of humans.

"My research has shown that rejuvenate themselves by activating the enzyme telomerase, and in this way extending their chromosomes and protecting their . They also have a special ability to discard 'junk' from their cells. Older parts of the animal are quite simply broken down, and are then partially recycled when new and healthy parts grow out from the adult bodies."

Some species of starfish reproduce asexually by tearing apart their bodies, while others reproduce sexually only. This makes them particularly interesting animals to study. Both types of starfish can reconstruct lost body parts, but the species that reproduce asexually have considerably better health.

However, one consequence of asexual reproduction is that the species as a whole will have a very low genetic variation. This means that they will be particularly vulnerable to climate change, and the subsequent new types of changes in the environment. There is a high risk that these animals and plants will loose out – and then we will loose important knowledge about the riddle of ageing.

Plants won't "loose" out but they may lose out. We won't "loose" important knowledge, but we could lose important knowledge, like the knowledge of the correct usage of words!

it's not a riddle..
...That is why, just as through one man sin entered into the world and death through sin, and thus death spread to all men because they had all sinned... Romans 5:12

So the reason that dinosaur's died was because Man sinned? Is that your explanation?

If so when was the Flood?

Any bets that 6_6 ignores this post? Or at very most responds but ignores what I really said.

You might keep the source in mind. English is the not the first language in Sweden.

The original paper was written by Helen Nilsson Sköld and Matthias Obst.

Link to abstract. I am not paying to read the whole thing.

Neither lose or loose is in the abstract. Anita Fors wrote the article for the University.

This is the reason all things die. Man chose not to obey (sin) and death entered. As to when the flood was there are many theories with their different timelines. That is not relevant to the question of sin and death. Dinosaurs and man lived concurrently in spite of what the theorists say. There are a number of fossilized records of human and dinosaur footprints running side by side along ancient stream beds.

Very wrong. There has been death on Earth for billions of years before Man existed.

There is only one that matches the physical evidence. There was no Flood.

That is not relevant to the question of sin and death.
It is relevant to believing a book written long ago by men that knew nothing about the real geological and biological history of life on Earth.

Dinosaurs and man lived concurrently in spite of what the theorists say.
There is absolutely no physical evidence to support that. It is FACT not theory that humans and dinosaurs did not coexist.>>

False. There are fossil footprints of Dinosaurs and DINOSAURS but not one of any human. Some of the alleged human footprints are twice human size and are clearly not human in any case to anyone COMPETENT. There are however some FAKE footprints and the fakers have admitted to it.

Looks like I get no takers. He has no guts. You have no evidence but you do have more guts.>>

There is a reason I ask when the Flood was. If you give the answer you think is correct I will tell you the reason. The Discovery Institute is fully aware that the Flood is impossible to reconcile with reality so they have told people to avoid discussing it. They don't discuss the problems with the Flood themselves they just evade all such questions. 6_6 is not the only person making hit and run posts and avoiding any discussion. It is now a standard practice of Creationism Trolls. None of them have the guts to put there beliefs to the test of an honest evidence based discussion. Ten years ago Creationists still had some courage. Now they don't, not here anyway.

There is only one reason to avoid discussing physical and historical evidence that SHOULD exist if the Bible was true. And that is there is no such evidence.
