Life is a chemical reaction. Three major transitions in early evolution are considered without recourse to a tree of life. The origin of prokaryotes required a steady supply of energy and electrons, probably in the form of molecular hydrogen stemming fro

In the case of a Friedmann universe, where and evolve in time, the quantities of interest, as we will see in Sect. 2.2, are and , instead of and , with the ‘tilded’ quantities being time independent. For this reason, and for the sake of simplicity, we take in Eq. (1), ...
All living things begin as one cell with one copy of DNA. The laws of engineering prove that all the instructions to wire up and assemble a human must be contained in that one strand of DNA. We are not talking just "genes" here but point to point wiring instructions for all neurons, ...
In these mRNAs, the start codon is located either directly at the 5′-end or at a short distance from it. In this case, translation begins with the binding start codon by the associated 70S ribosome. In vitro studies have shown that although initiation factors do not play a key role in...
In the model system Drosophila melanogaster, doublesex (dsx) is the double-switch gene at the bottom of the somatic sex determination cascade that determines the differentiation of sexually dimorphic traits. Homologues of dsx are functionally conserved i
