Are Seeds Alive?
Are seeds alive or not? Seeds have been
found in the desert and that are 4000 years old, but when put in moist soil, they grow. So where does the life come from? Is it generated when conditions are right? Or was the seed alive but dormant? Do the conditions make life? Can't find answers - I don't think anyone knows. |

Are Seeds Alive?
Yes seeds are alive.
Exactly which 4000 year old seeds found in the desert grew? Your line of reasoning (if it can be called that) is based on a fable and not fact. There are also examples of animals, especially frogs and lung fish, that can survive many years in hibernation and come out of it. But 4000 years is a bit much to believe or even prove. But then again there are the remarkable "water bears". http://www.q7.com/~vvv/tardigrade/ "Miss Chanandler Bong" wrote in message om... Are seeds alive or not?

Are Seeds Alive?
I took the 4000 year-old example from memory
and it may have been someone's exageration or a myth, but some web research yielded information about some seeds that remain viable after 1200 years. Here is a clip from that page: ----------------------------------------------------- LOS ANGELES -- Scientists studying the origins of life have germinated the oldest known seed ever found -- a 1,200-year-old lotus seed from China. "A little seed that slept for more than 1,000 years sprouted in four days just like its modern sibling," plant physiologist Jane Shen-Miller, of the University of California at Los Angeles, said Monday. Her husband, paleobiologist William Schopf, who heads UCLA's Center for the Study of Evolution and the Origin of Life, said: "It seems impossible for a plant miraculously to be brought back to life after more than 1,000 years." ------------------------------------------------------ source: http://www.flowerpictures.net/lotus/lotus_seeds.htm "Cereus-validus" wrote in message . ..

That's a far cry from a 4000 year old seed from the desert.
Still the 1200 year old claim is probably a bit of an exaggeration. After all, the seed was found in a bog even though that wasn't stated in your second-hand account. Beware of anecdotal "believe it or not" accounts. "Miss Chanandler Bong" wrote in message . com...

Are Seeds Alive?
Here is an example of the confluence between qualitative language and
incompleter scientific knowledge. The problem is with our language and limited direct experience with all the bizzare adaptations of life forms. The range of properties we expect of "living" material is expanding at a mindboggling rate with new research.. As we explore more of the environmental extremes on earth. we continue to find life existing in conditions which we thought impossible only a few years ago. I strongly suspect we will find life forms in other locations throughout the universe within a relatively short time period. One of the bizarre aspects of certain life forms is the ability to suspend metabolism when conditions dictate. It is a property which has been documented many times over. We ought not to be so shocked by the facts or limited in our ability to intregrate the knowledge. Here is one report of radiocarbon dated seed about 3000 years old being germinated. http://askabiologist.asu.edu/researc...seeds_old.html Another study of loongevity of seeds http://newsbulletin.msu.edu/july27/beal.html Accidental find.... http://abcnews.go.com/sections/scite...ard020314.html The oldest seed to germinate has not been found yet and the question is still open to future investigation because finding these old seeds to test is accidental.. .

Despite you verbose (are you getting paid by the word?) pedant, the examples
you are link are still anecdotal and they fail to mention exactly what plants these 400 year old seeds were. Are these supposed to be the same lotus seeds that another report claimed were 1200 years old? It sure look like they have gotten marked down along the way. Weed seeds are well know to survive dormant for very long time buried in deep soil but 400 years is a bit much. "Aaron" wrote in message ...

The first link, from Arizona State University, cited the work of Jane
Shen-Miller, a scientist working with old seeds. Her work is not annecdotal, it is REAL EXPERIMENTAL SCIENCE. The seeds were radiocarbon dated. Do a google search for her work and you will find many reports of seeds of varying longevity being germinated. Aaron .

A seed that germinates after 1,000 years would have been alive for those 1,000 years but in a type of suspended animation. It may or may not have been dormant. A dormant seed will not germinate even when environmental conditions for germination are optimal. Many seeds are not actually dormant, but merely quiescent. Quiescent seeds will germinate promptly when exposed to environmental conditions optimal for germination. Most flower, vegetable and lawn grass seeds are quiescent rather than dormant. Aaron posted some links about the Beal seed longevity experiment. Fritz Went started a similar experiment in 1947 with seeds sealed in a vacuum. He intended the experiment to last 360 years. http://www.ou.edu/cas/botany-micro/b...tracts/1.shtml Biology textbooks often list from four to seven characteristics of life. They might be of use in your determination if seeds are alive. http://128.252.223.112/posts/archive...6518.Bt.r.html http://128.252.223.112/posts/archive...2472.Bt.r.html Seeds are often very tough. For long term storage, seeds are routinely kept at liquid nitrogen temperatures. NASA put thousands of tomato seeds into orbit for over 5.5 years. The seeds germinated well when returned to earth. http://www.worldandi.com/specialrepo...er/Sa20717.htm |
