A palaeontological perspective
Current Opinion in Genetics & Development, 1994Palaeontology and molecular biology researchers need to develop a better dialogue. The recovery of biological information from Precambrian ecosystems that are thousands of millions of years old, the search for radical genomic reorganizations that might explain the irruption of groups with novel body plans, and the recovery of diagnostic molecules from ...

Proteins and molecular palaeontology
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1991Abstract Protein taxonomy has existed as a concept at least since 1958, but despite the efforts of the past 30 years, comparative studies of protein sequence, structure and distribution have not revolutionized any areas of systematics.

The concept of the biospecies as a comprehensive taxon is, however, only notional amongst the vast majority of living organisms, and it is not directly applicable to fossils.
