Re: Theories - Origin of Life

aptitude Because the ribosome seems to be ubiquitous in almost all organisms, the ribosome must have originated very early in the history of life. Ribosome evolution began with a complex of nucleic acids that probably had another function early on, but acquired the function ...

... funny, scottie. You are arguing that the cell cannot function since the ribosome is part protein, and the ribosome is responsible for peptide synthesis; ... very early in the history of life. Ribosome evolution began with a complex of nucleic acids that probably had another function early on, but ...
