Worldmapper Timeline of the Universe | Future Collision Andromeda | Future | Timeline Planet-sized computers dominate the Local Group of galaxies; humanity's descendants are a Type 3 civilisation on the Kardashev scale Purely biological (non-cyborg) humans are exceedingly rare now. The very few which do remain comprise only a tiny fraction of the total sentient minds in existence. Though free to come and go as they please, they have practically zero influence in any governmental systems on Earth or elsewhere, being regarded as wholly subordinate to AIs and other entities. As a species, homo sapiens has continued to evolve over time. This has led to a further increase in cranial size, a near-total absence of hair, an elongation of limbs, a more robust and capable immune system, and increased lifespan. The vast majority of humans have long since abandoned these primitive biological forms, making the transition to machines or other substrates and achieving practical immortality. A number of alien intelligences have been contacted by now. © Randall Mikulas | Dreamstime.com

EarthViewer Change The Way You See The World In 82 Seconds Earth Wind /Ocean Map Understanding Evolution The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. Read the rest of the story here | See the Evo in the News archive

100 Year Starship Night Earth Evolution Resources from the National Academies In the News: Your Inner Fish – A Scientific Adventure Have you ever wondered why people look the way they do? Why our hands and feet have five digits instead of six? Why we stand on two legs instead of four? Follow that adventure now on PBS Darwin's Insights Continue to Inspire the Academy's Work The ideas of Charles Darwin and the concept of evolution by natural selection continue to have a profound influence on modern biology – they permeate almost every area of scientific exploration. In 2009 the National Academy of Sciences joined many other organizations in the international scientific community to celebrate the 'Year of Science,' which commemorated Darwin’s 200th birthday and the 150th anniversary of the publication of his masterwork On the Origin of Species. In 2010, the National Academy of Sciences awarded its most prestigious award, the Public Welfare Medal, to Dr.

10 Space Myths We Need to Stop Believing Why you shouldn’t get your facts from Hollywood. 1. We explode in space Like many of the myths that will follow, this idea was mostly created by Hollywood. Oftentimes, moviemakers aren’t really that concerned with the facts. They will readily take liberties with reality in order to make a scene look more interesting. Exposure to space will definitely kill you, but not instantly and not in such a visceral way. 2. Venus is often referred to as our twin but this shouldn’t give you the impression that it is exactly like our planet. 3. The Sun is actually glowing, not burning. 4. Ask anyone to draw a Sun and they will immediately reach for the yellow crayon. Thing is, though, that we see it yellow thanks to our atmosphere. Regardless, we don’t need to see the Sun to know what color it is because we can tell from the temperature. 5. At a glance, this one seems logical enough. What isn’t a myth, however, is the idea that the Earth is sometimes closer and sometimes further away from the Sun. 6.
