Biological natural selection often requires hundreds or thousands of years to conspicuously change a population, but this won’t be the case for AIs. The important ingredient is not absolute time, but the number of generations that pass. While a human generation drags along for decades, multiple...
All organisms carry traits that no longer confer any real benefit to them in terms of natural selection. If the trait doesn't harm the organism, then natural selection won't weed it out, so these traits stick around for generations. The result: organs and behaviors that no longer serve the...
activity other than feeding at dusk (Fig.2b). The analysis of the 3 early morning periods from all 15 days of the 5 replicates indicated that fly numbers at the grapes increased during the morning. There were more males than females on grapes but no change in fly numbers over the 3 days...

Here is an explanation of Wilson’s change of mind: Wilson said he first gave voice to his doubts in 2004, by which point kin selection theory had been widely accepted as the explanation for the evolution of altruism. “I pointed out that there were a lot of problems with the kin select...
All life forms represent the simplest of prokaryotes (unicellular organisms that do not have a nucleus) or forms that arose from them through natural selection. Evolution is a progression of change within populations to environmental pressures. The chapters in this book discuss the similarities and ...
and Bonan2019; Baunaz2011; Cheng and Rooryck2000; Mathieu2002, for a stand similar to ours on Colloquial French). Indeed, the theory predicts that thewh-term should always be rightmost (i.e., the “sentence-finality requirement”), whereas Colloquial French displays sentences likeT’as vu ...
The selection of best energy source or combination for MD technology, which considers the dynamic energy availability, capital cost, and the MD energy efficiency synergistically, will facilitate the practical implementation of on-site UOG wastewater treatment, thereby promoting water sustainability in the...
A number of bacteria can directly induce carbonate minerals35,36,37. At indirect carbonate precipitation, the microorganisms do not influence the precipitation, it is only a side effect of their influence of the environment due to their metabolism, e.g. uptake or production of CO2or pH change....
This information would also provide a stronger basis for risk assessment and for the selection and operation of appropriate remedial systems. Natural attenuation of BTEX contamination relies heavily on anaerobic biodegradation processes (Rifai et al., Alvarez et al. The effect of fuel alcohol on mono...
