Microbes Are Forever
Well, maybe not forever. But micro-biologists have found single celled organisms on the bottom of the deep sea that have a completely different relation to time and energy, and they can live for hundreds of thousands of years, maybe even millions of years...
Regular visitors of this blog might have noticed that I love science. That's why I regularly check up on the latest TED-talks. A while ago one of these talks inspired me to go look for strange and beautiful life forms in the dee sea that I presented in this post. Now, as wonderful as all those are, I recently had the pleasure of listening to Karen Lloyd's TED-talk about some startling discovery on the oceans' floors.
One of the things I wanted to find out as a kid was what the oldest living things on Earth are. The undisputed king in that particular ranking has for the longest time been some Bristlecone Pine tree, the latest being this one:
5,067 year old Great Basin Bristlecone Pine

But I was so wrong... There's even a term called biological immortality:
Biological immortality (sometimes referred to bio-indefinite mortality) is a state in which the rate of mortality from senescence is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or after living long enough. A biologically immortal living being can still die from means other than senescence, such as through injury or disease.

In the TED-talk Karen Lloyd takes us on a journey to the mud on the ocean's bottom. Some microbes survive under circumstances that differ so greatly from our surroundings in the sunlight, that they change our understanding about life on earth. What's especially remarkable is the very low energy requirements and the total lack of any day-night cycle these microbes live with. The effect of this is that these organisms live in a totally different "rhythm" than all surface-dwelling life on the planet, and that they can reach extreme old ages.
Naturally I went looking for confirmation of this remarkable claim, but this has been known for quite some time now. Here's what we find in Wikipedia under the heading "List of longest-living organisms":
Some endoliths have extremely long lives. In August 2013, researchers reported evidence of endoliths in the ocean floor, perhaps millions of years old, with a generation time of 10 millennia. These are slowly metabolizing, not in a dormant state.

Perhaps millions of years old... Imagine if that microbe could tell tales... But I bored you long enough with needless talk about age; you're getting old reading this ;-) So here's the talk that amazed me and got me thinking about life's fleeting nature:

I hope you enjoyed that as much as I did! Thanks for visiting, and I hope you'll be back tomorrow :-)

After reading this, and watching something lastnight about organisms being algorithums, then dam me john! This is my prediction of where bio engineering will come from for the future human species!!

Well shit. For at least 20 years I've had the notion that when this meat wrapped skeleton of mine no longer serves a purpose for me I'd have it either liquefied or cremated and supplied to the tree pictured above. And thereby become part of the oldest living being in earth. And now, thanks so fucking much, I have to reconsider my posthumous plans. Jeez Rick. What a hassle. Here I thought I had it figured out but noooooooo.... I know nuzzing lebowski
That's exactly what happened to me! I was so surprised to learn about these microbial buggers... :-) Thanks for sharing my amazement @naturowlmystic :-) And sorry for crushing your postmortem dreams... ;-)
Hahahahaha it's all a dream probably so no worries!
Your article is very good, my game is very fun. https://goo.gl/Dd9394
