They used this information to measure the ecological and evolutionary structure of each community, trying to find out whether it was best explained by present-day climate, Quaternary paleoclimate changes, recent human activity or prehistoric human activity. Their findings show, for the first time, th...
some of the fight scenes were forgettable, and important characters fromMK’s canon were not given too much time to shine. That said,Mortal Kombat 2has all the ingredients to improve upon the first movie, and the behind-the-scenes pictures have all been very promising. ...

Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive?Using genome sequencing, researchers from McGill University show that some fish, like...
While GHG concentrations—and thus their forcings—fall from 2070 to 2150, the effect of surface albedo continues on its smooth upward path throughout this period. Its time development is much slower than that of GHGes. It is the result of mainly Arctic ice melting—but it has enough ‘...
This is the first time that chimpanzees have been seen applying insects both to their wounds and to the wounds of others in their community. While animals have been spotted self-medicating before, those instances have mostly involved the animal simply consuming beneficial plants or insects, rather...
"Although most studies of bird plumage focus on dichromatism, evolutionary change has most often led to similar, rather than different, plumage in males and females," the authors write. Peter Dunn and Linda Whittingham, professors of biological sciences at UW-Milwaukee, wrote the paper with Jess...
aWhile the first may well aspire to positivist science, the second is evolutionary and clearly quite different. Kuhn's (1970) analysis of paradigm change is another version of this same multilevel approach. 当一个也许将向往到实证主义者科学时,秒钟是演变和清楚地相当不同的。 对 (范例) 变动的...
Our findings support a growing body of evidence showing stable and sustainable communities on the island. The ABC framework offers a novel approach for exploring regions and time periods where questions of climate-induced demographic and cultural change remain unresolved....
To understand the mathematics of the shape of DNA, you need to consider both its geometry and its topology. These are related but distinct concepts. Geometry describes an object at a particular moment in time – frozen rigid in space, like a sculpture. In the cell, the DNA helix coils upo...
