At first sight such claims appear to have considerable justification, but when the fossil evidence is closely examined it can be shown that there are some grave deficiencies, and the claim is not only factually unproved but also contains a ...

Protein fossils live on as RNA

A central challenge in genome annotation is determining the function of sequences that do not encode proteins, but make up the overwhelming bulk of large genomes — some 99% in humans. A significant fraction of these sequences are pseudogenes, or fossils of ancient proteins, and although many of them are transcribed into RNA, they have hitherto been deemed ‘junk’. However, given the abundance of...
