Why is all life carbon-based? By Graham Templeton 10.

  • August 2015 "What we normally think of as 'life' is based on chains of carbon atoms, with a few other atoms, such as nitrogen or phosphorus", per Stephen Hawking in a 2008 lecture, "carbon [;;;

Almost universally, this element is silicon, but some writers have gone further afield in imagining totally novel forms of life — for instance, Carl Sagan once imagined life forms that could evolve and thrive in the gaseous sea that is Jupiter aside from its core.

Still, why do most writers consistently turn to silicon as the most likely carbon substitute? And why is carbon the basis of all life currently known? Basically, the answer is that life is complex, and more to the point that it must be complex. Probably not how silicon based life would actually look.

  • Unsourced material may be challenged and removed;
  • None are synonymous with best case study writer services for university sustainable agriculture; blog post ghostwriters for hire gb each relates to.

The reason carbon has this property is somewhat complicated but can be boiled down to this: There are only a few elements that can do this naturally. Oxygen, for instance, will naturally form two bonds think H2O. The four-bond structure allows a wide variety of possible chains with branches that have branches that have branches.

This is why science fiction tends toward postulating silicon-based life: Looking further down the list brings us to less used elements like Germanium and Tin — these heavy elements are large and unwieldy, forming weaker bonds than their higher vertical neighbors because they hold other atoms a greater distance from their nucleus.

Within the class of elements that can form complex molecules, carbon has helpful chemical properties for making and breaking chemical bonds.

We already know of several thousand species that use silicon extensively in their overall biology — but none of them use silicon in DNAso they are still considered to be carbon-based. Carbon forms strong double and triple bonds, not just allowing the branched structure of DNA but protecting that structure with strong chemical properties.

  1. March 2015 Learn how and when to remove this template message The most notable groups of chemicals used in the processes of living organisms include.
  2. This is because hydrogen effectively serves as a linking element between the carbon base of a chain and other elements; hydrogen's high level of electronegativity is what allows it to play this role. A protein is a compound that is used in cells to signal what actions the cell needs to take; effectively, proteins translate the passive codes of the DNA into actions.
  3. His articles have appeared in the collegiate newspaper "The Red and Black.
  4. All life forms will be based on it.
  5. By Graham Templeton 10. Basically, the answer is that life is complex, and more to the point that it must be complex.

The fact is that life probably could technically arise from a wide variety of molecules, but carbon seems to be by far the most likely. A species based on silicon might be funneled down roughly similar evolutionary paths as a carbon-based one, but something based on, say, phosphorus could turn out totally unrecognizable.

Everything from its physical structure to its method of genetic inheritance would have to be wildly different. When imagining alien species, the most outlandish concepts would start not from a different environment, but from an totally different sort of chemistry.

  1. We already know of several thousand species that use silicon extensively in their overall biology — but none of them use silicon in DNA , so they are still considered to be carbon-based.
  2. The chief delayed effect is the creation of huge amounts of radioactive top dissertation hypothesis editing sites for university material popular case study editing service for college with long lifetimes. Carbon All known living organisms on Earth are carbon-based organisms.
