Nick Lane Takes on the Origin of Life and DNA
Recently, Nick Lane, a biochemist and Provost’s Venture Research Fellow in the Department of Genetics, Evolution and Environment at University College London, published a new book, Life Ascending: The Ten Great Inventions of Evolution. Nick Lane lays out ten biological phenomena for which he seeks to propose plausible evolutionary explanations. Among the phenomena discussed by Lane are the origin of life, DNA, photosynthesis, the complex cell, sex, movement, sight, hot blood, consciousness, and death. But does Darwinism have the goods? Or does Nick Lane offer us only a series of wishful speculations? New Scientist offered the following praise for Lane’s work: What makes this such a great read is that Lane, a biochemist by training, does not simply rehash the Read More ›
The ‘Junk DNA’ Paradigm Continues To Collapse As New Functions Are Discovered For Retrotransposons
The literature continues to flood in demonstrating that so-called ‘junk’ regions of the genome are not junk after all, but serve significant and important functions. One such recent paper reports evidence that retrotransposons may play significant roles in the cell. According to the abstract, Retrotransposons including endogenous retroviruses and their solitary long terminal repeats (LTRs) compose >40% of the human genome. Many of them are located in intergenic regions far from genes. Whether these intergenic retrotransposons serve beneficial host functions is not known. Here we show that an LTR retrotransposon of ERV-9 human endogenous retrovirus located 40–70 kb upstream of the human fetal γ- and adult β-globin genes serves a long-range, host function. The ERV-9 LTR contains multiple CCAAT and Read More ›
