An Early Earth Predisposed to Phosphorylation of Organics

The element phosphorus is important in the development and possibly origin of life on the earth. The formation of phosphorylated organics, such as those found in all life today, does not occur easily under plausible prebiotic conditions. Here I present new results on the chemistry of phosphorus in the Archean as sampled from the 3.52 billion year old limestone that shows a fundamental difference between archean phosphorus and the modern phosphate cycle. Additionally, I will show how these differences could have influenced the prebiotic chemistry of early environments from a "just add water" perspective.

What do biosignatures tell us

Started by Ken Jones in SAGANet Community Jul 11. 0 Replies

Lately there has been a lot of talk about biosignatures. I've even come across articles where they talk about using biosignatures to look for life beyond earth in the rocks here on earth by searching for biosignatures of past life in rocks. I'm just…Continue
