Massive genetic study shows how humans are evolvingAnalysis of 215,000 people's DNA suggests variants that shorten life are being selected against.doi:10.1038/nature.2017.22565Bruno MartinNature
You still have to share it. You still want to understand whether or not it's going to show up in the SERP. You're going to use elevation to ensure that it's ultimately set up to do that, but you're going to do it much faster because you embraced the evolution of content. Content...
the islands where the dovekies breed. and you can imagine as that ice gets farther and farther away, the dovekies have longer and longer to travel to reach a place where they can get food for their offspring. and they have long been predicted to be an early casualty of climate change....
All across the globe, I've seen cultures who have been living with floods for thousands of years by evolving these ancient technologies that allow them to work with the water. In the southern wetlands of Iraq, which are formed by the confluence of the Tigris and the Euphrates rivers, a un...
Stories about dinosaurs have existed for as long as people have been aware of the existence of trackways and fossils. Some researchers suggest that legends of behemoths and dragons come from the discovery of dinosaur bones and footprints [source: Sanz]. There are also cave paintings that appear...
However, it’s not without its challenges. The work itself is dangerous in nature, requiring welders to be up close with extremely high temperatures, molten materials and welding fumes. The work can also be repetitive, involving long simple welds or hundreds of identical welds. Perhaps unsurprisin...

I have looked long and hard, as a biologist, into the various issues surrounding vegetarianism, and I have concluded to my own satisfaction that a vegetarian diet is: (i) better in terms of the ethics of animal suffering (though not as good as a vegan one); (ii) better for the ...
this long-lived species in response to a decade and a half of human hunting. 我把读书最后的几年花 在研究非洲大象的进化,以应对象牙偷猎。在莫桑比克,1977到1992年之间, 发生了一场内战。这段期间,戈龙戈萨国家公园里 (Gorongosa National Park)大象的数量减少了百分之九十象牙贸易,让大象因其标志性 的...
Dozens of genes previously thought to have similar roles across species are in fact unique to humans
