Researchers challenge a popular scenario put forward to explain the arrival of the first eukaryotic organisms

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the planet. Matters would remain largely unchanged in terms of evolutionary development in these so-called prokaryotic cells-;the bacteria and archaea-;for another billion and a half years.

Unnatural DNA bases: an interview with Professor Floyd E. Romesberg, The Scripps Research Institute

The natural DNA bases that form the letters of DNA are usually referred to as G, C, A, and T. Those are only the first letters of the chemical names. They’re often called nucleotides by their scientific name and all of them have in common a phosphate part, a sugar part and a nucleobase part.
