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
and the lengthening of cortical RG cell cycles is a well-documented feature of primates with larger brains [66,120,125,126,127]. Human cortical RG cells likely have the longest cell cycle and the longest neurogenic period. Humans also have the longest gestation period among ...
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), ...
Using the platinum-based mutational signature as a barcode, we determine that the clonal expansion originating the secondary AMLs begins after the start of the cytotoxic treatment. Its absence in clonal hematopoiesis cases is consistent with the start of the clonal expansion predating the exposure to...
We review some recently published results on sex chromosomes in a diversity of species. We focus on several fish and some plants whose sex chromosomes appear to be ‘young’, as only parts of the chromosome are nonrecombining, while the rest is pseudoaut
TheCambrian explosionbegins, withmany new body layoutsappearing on the scene – though the seeming rapidity ofthe appearance of new life formsincreasingly looks like an illusion asever more older fossils come to light. 530 million years ago ...
Genes associated with the neurodevelopmental disorder microcephaly display a strong signature of adaptive evolution in primates. Comparative data suggest a link between selection on some of these loci and the evolution of primate brain size. Whether or n

Whatever most people think evolutionary is for the most part a pure parody14 of the evolutionist's opinion. But a more serious error than all these pervades what we may call the drawing-room view of the evolutionist theory. So far as Society with a big initial is concerned, evolutionism ...
Bayesian Networks (BNs) offer a potential solution. BNs can capture spatial–temporal relationships and causal factors in habitat change. BNs are probabilistic models that use Bayes’ theorem to study causal relationships [36]. The construction of the model begins with prior knowledge, while ...
