Ever since the 1993 film based on Michael Crichton’s novel Jurassic Park was released, the thought of reviving extinct species using molecular biology techniques has been on the forefront of the collective imaginary.

The ribosome may be a missing link in the evolution of life. This suggestive proposal has been published by Meredith Root-Bernstein, Oxford University, UK, and her father Robert Root-Bernstein, Michigan State University, USA, in the Journal of Theoretical Biology . Their hypothesis is that primordial ribosomes were self-replicating intermediates between the prebiotic world and the […]
