Historically, attempts to elucidate evolutionary relationships among members of the genus Epinephelus (Teleostei: Serranidae), commonly known as groupers, have been hindered by the overwhelming number of species (98, sensu stricto), a pan global distribution, and the lack of morphological specializations traditionally used in ichthyological classification. To date, no comprehensive phylogenetic study, morphological or molecular, to evaluate the monophyly of this genus has been presented. In this study, previous hypotheses regarding the relationships among the American grouper species and the allied genera were evaluated by examination of mitochondrial DNA sequences of the 16S ribosomal DNA region. A 590-bp region of the …

Genetic Biotechnology And Evolutionary Theory: Some Unsolicited Advice, David Depew
David J Depew
In his book The Biotech Century Jeremy Rifkin makes arguments about the dangers of market-driven genetic biotechnology in medical and agricultural contexts. Believing that Darwinism is too compromised by a competitive ethic to resist capitalist depredations of the “genetic commons,” and perhaps hoping to pick up anti-Darwinian allies, he turns for support to unorthodox non-Darwinian views of evolution. The Darwinian tradition, more closely examined, contains resources that might better serve his argument. The robust tradition associated with Theodosius Dobzhansky, Ernst Mayr, and others provides an alternative, scientifically sound basis for challenging the rhetoric of genetic reductionism.
