How Did Life Originate?naturalists adopted the idea that living organisms were the historical outcome of gradual transformation of lifeless matter. These views soon merged with the developments of biochemistry and cell biology and led to the proposals by Oparin and Haldane of a heterotrophic theory of the origin of life,

A Vestige of an RNA Apparatus With Ribozyme Capabilities Embedded and Functions Within the Modern Rinter. This embedded architectural element is a dimer of RNA chains with a pocket-like structure, which functions in peptide bond formation. We suggest that it represents an ancient apparatus for performing chemical reactions required in the RNA world era, with peptide bond formation capabilities, ca

Role of Symbiosis in Evolutione Genomic era, allowing deep knowledge on single or consortia uncultivable species. The establishment and maintenance of symbiosis are complex issues where partners’ fitness determines the evolutionary outcome. Comparative genomics allows to dissect the evolutionary process that begins with host inv

Endosymbiosis and the Origin of Eukaryotesntellectually stimulating articles being published these days. The phenomenon of cells living inside other cells has had an enormous impact on the evolution of life. This has occurred on the macroscale with the endosymbiotic origin of numerous phyla of eukaryotes including the primary photoendosymbi

Epochal Change: Sweltering Climate at the Paleocene–Eocene Boundary (55 Million Years Ago)million years (Ma) suggests a massive injection of biogenic methane into the ocean/atmosphere system. The clathrate gun hypothesis (Kennet et al. 2003) proposes that changes in the temperature of intermediate seawater led to a destabalization of methane hydrates, produced by anaerobic chemotrophic a

Insight into Speciation From Long-term Research on Darwin’s Finchesl species that colonized the Galápagos 2–3 million years ago. Each species occupies a distinct and unique feeding niche. For evolutionary biologists, they pose a challenge. What is the explanation for the evolution of such a variety of species in a relatively short space of time? What governs the ra
