Abiogenesis is a science that studies how life on Earth came to be from organic and inorganic molecules. The word is made of two parts (one relates to Ancient Greek "bios" - life; the other to "genesis" - birth or origin). Some people talk about Chemical Evolution.

People like Jean-Baptiste de Lamarck and Charles Darwin saw that the plants and animals on earth change over time. They developed theories to explain this phenomenon: de Lamarck developed Lamarckism, and Darwin developed the Darwinian therory of Evolution. This article is not about biological theories of evolution, it looks at the chemical aspects.

A scientific study done in 2002 says that geological formations like the stromatolites shown in the picture do in fact contain 3.5 billion year old fossilized algae microbes. If this study is true, they would be the oldest known life on earth.

According to scientific research, abiogenesis happened sometime between 4.4 billion years ago, when water vapor first liquefied, and 2.7 billion years ago, when the ratio of stable isotopes of carbon (12C and 13C), iron (56Fe, 57Fe, and 58Fe) and sulfur (32S, 33S, 34S, and 36S) points to a biogenic origin of minerals and sediments and molecular biomarkers indicate photosynthesis.

Even though it has a great impact on biology and how people understand the world, Abiogeneis is in fact a very limited field of study. Progress is sometimes slow, but If progress is made, now and then, it causes big attention. This is because the question
