And the original question examined by Charles Darwin—what is the mechanism that causes new species to evolve—has yet to be fully explained. And another related question looms: How important are chance events, as opposed to natural selection, to shaping organisms? Another Great Mystery: Why Do...

Contemporary context properties such as turbulence, chaos and high velocity are explained as important exogenous determinants of evolution. Variation understood as a process of adaptation is an important evolutionary mechanism. As a result of the foregoing considerations it is concluded that...
development across the entire state of Florida using a dataset containing nearly nine million parcels. Further details on the machine learning and econometric approaches employed here are given in the following sections. Meanwhile, the next paragraphs go to the matter at hand—what drives urban ...
Telomere erosion in proliferating pre-neoplastic cells functions as a tumour suppressor mechanism that cancer cells can bypass by engaging telomere elongation pathways. The recent identification of mutations affecting telomere-associated proteins in cancer samples suggests that telomere deprotection has a ...
It is the departure from holographic equipartition that drives the time evolution of the spacetime. This result, which is equivalent to Einstein's equations, provides an elegant, holographic, description of spacetime dynamics. 展开 关键词: Emergent gravity horizon entropy Noether current holography ...
