Natural selection fosters certain qualities so aliens shouldn’t look extremely different from humans.
Once with the advent of agriculture, and its spread to Europe from the Near East, human society was transformed forever. Resources became more plentiful, communities could stay in one place and develop, and humans were free to pursue other activities. Agriculture turbo boosted the division of labor, an essential prerequisite to any civilization. Agriculture not only transformed human society, it also modified our DNA. A first of its kind study compared the DNA of ancient humans who lived between 8,500 and 2,300 years ago. The analysis revealed that humans underwent widespread genetic changes that influence height, immune system, digestion and skin colour once agriculture was introduced.
Scientists have made a significant step towards developing fully artificial life – for the first time, they demonstrated evolution in a simple chemistry set without DNA. In a way, the researchers showed that the principle of natural selection doesn’t only apply to the biological world. Using a simple a robotic ‘aid’, a team from the University of Glasgow managed to create an evolving
Charle’s Darwin’s original notes during which he first scribbled down the ideas which led to evolution have been digitized and published online by Cambridge University. Over 12,000 high-res images have been published online – including the ones with the pages where he actually coins the term ‘natural selection’. “One may say there is a force like a hundred thousand wedges
An exceptional Biologists duo who have studying an ecosystem from the Galapagos Islands for the past 40 years have made one of the most important discoveries in evolutionary biology – the birth of a new species!
Though Siberia stretches across about 10% of the world’s land surface, it’s only occupied by 0.5% of the world’s population, which isn’t too hard to explain why. Recent temperature measurements read on average -25°C for the month of January, but it’s not unheard of to experience temperatures below -40°C. Extreme weather, temperatures and terrain, however, call for extreme humans, and who
Evolution, in very loose lines, is defined as the process which allows a species to survive by passing on the differentiating traits most likely to help offspring adapt to the world through means of natural and sexual selection. Considering the world around us has been shaped so much by human hand, a lot of people have questioned whether the natural
