Molecular Clocks of Evolution, 1989-11-28 - 1989-12-01

 File

Scope and Contents

The meeting Molecular Clocks of Evolution discussed how a considerable amount of data has been produced using differences in DNA between different species to measure the relatedness of species. Some of the data obtained using DNA as a molecular clock have required radical revision of previously accepted taxonomic relationships, and the purpose of this meeting was to examine whether the assumptions underlying the use of molecular clocks are justified. Data was presented with time scales measured in millions of years rather than the minutes or hours of conventional molecular biological data.
