Haldane's 'Causes of Evolution' after 60 years

Article Abstract:

J.B.S. Haldane published his work, 'Causes of Evolution' in 1932. To determine the specific knowledge or misconceptions it may have contributed since then, an analysis of Haldane's work and the progress in the field of genetics since its publication was conducted. The analysis showed that Haldane was instrumental in stripping genetics of many misconceptions, like Lamarckian soft inheritance, orthogenesis and saltationism. In retrospect, Haldane was never really wrong in his interpretations, although he may have underestimated the importance of isolation for speciation and selection for reproductive success.

The establishment of evolutionary biology as a discrete biological discipline

Article Abstract:

The establishment of evolutionary biology as a credible science was hindered by the presence of contradicting and varied evolutionary theories and lack of support from recognized scientific organization. The acceptance of evolutionary biology as a formal science was mediated by novel discoveries and problems encountered in paleontology, genetics and systematics. Furthermore, evolutionary biology was needed to analyze the evolutionary aspects of molecular biology and physico-chemical factors in phylogenetics and systematics.

A mammalian molecular clock?

Article Abstract:

The molecular clock hypothesis proposed by Zuckerkandl and Pauling states that nucleotide and amino acid sequence mutation is a stochastic process. Various studies to determine the absolute and relative rates of molecular evolution imply that there is little variation in the mutation rates of mammalian lineages. However, additional studies are needed to reach a definitive conclusion.
