I'd like to understand more about how/why carbon-based life comes about. All things are atomically based, why is it that carbon atoms/elements are able to sustain life better than any other element?
Pythagorean said:Carbon is a very diverse bonding element. It has four valence electrons, which make it able to bond with oxygen, nitrogen, and hydrogen; further, it's bonding strength in "standard" temperature and pressure is right at the point where it can construct both reactive and stable molecules. Finally, carbon forms chains with itself that can lead one molecule to have many different "conformations".
Carbon is considered the building block of life because it is a versatile element that can form strong bonds with many other elements, allowing it to create a wide variety of complex molecules. These molecules serve as the building blocks for all living organisms, including proteins, carbohydrates, and nucleic acids.
Carbon plays a crucial role in supporting life on Earth through its ability to form strong bonds with other elements like hydrogen, oxygen, and nitrogen. These bonds are essential for creating the complex molecules that make up the cells and tissues of living organisms. Additionally, carbon is a key component of the Earth's atmosphere, helping to regulate the planet's temperature and making it habitable for life.
While carbon-based life forms are the only known type of life on Earth, it is possible that they could exist on other planets. This is because carbon is one of the most abundant elements in the universe and is found in many different environments. However, the conditions on other planets may be vastly different from Earth, so the exact form of carbon-based life forms may vary.
The atomic structure of carbon is unique in that it has four valence electrons, allowing it to form strong covalent bonds with up to four other atoms. This allows carbon to create a wide variety of molecules with different shapes, sizes, and properties. It is this versatility that allows for the incredible diversity of life on Earth.
While there is no definitive answer, it is possible that carbon-based life forms could evolve into other forms. Evolution is driven by genetic variation and natural selection, and carbon-based life forms have shown a remarkable ability to adapt and evolve over time. However, the exact mechanisms that would drive this evolution into new forms are still unknown.
