Journal of Monetary Economics, 2012 Abstract Agriculture sector output (biocarbon) is a good substitute for oil in energy production but oil cannot be used as food. This one-way substitutability is analyzed in a dynamic general equilibrium model. It features three endogenous phases: a pure fossil, a mixed fossil and biocarbon and an absorbing biocarbon fuel only phase.

Archean molecular fossils and the early rise of eukaryotes.
Science, 1999Molecular fossils of biological lipids are preserved in 2700-million-year-old shales from the Pilbara Craton, Australia. Sequential extraction of adjacent samples shows that these hydrocarbon biomarkers are indigenous and syngenetic to the Archean shales,

Mites as fossils: forever small?
International Journal of Acarology, 2018Smallness being in the essence of a mite, the question is whether it has always been so during the geological history of Acari. Here I assemble measurements of over 260 published mite fossils, distributed from the Early Devonian (410 mya) to the end of ...

Origins of Life, 1976A comparative statistical study has been carried out on populations of modern algae, of Precambrian algal microfossils, of the 'organized elements' of the Orgueil carbonaceous meteorite, and of the oldest microfossil-like objects now known (spheroidal bodies from the Fig Tree and Onverwacht Groups of the Swaziland Supergroup, South Africa).

The origin of fossils After an animal dies, its behavior immediately stops. Of course! Thus, behavior is the first component of the phenotype to be lost. After this, DNA and soft tissues are also rapidly lost. Large and small animals may eat or scavenge the carcass, dismembering the body, stripping away flesh, and breaking open bones that are rich in

This article comments on the persistence of the creationism argument despite the multifarious evidence supporting evolution. Nineteenth-century English social scientist Herbert Spencer made this prescient observation: "Those who cavalierly reject the Theory of Evolution, as not adequately supported by facts, seem quite to forget that their own theory ...
