Long-Term Climate Factors Led Early Humans Into Patchwork Evolution

RedOrbit: In the past, scientists concluded many of mans defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately. Based on analyses of fossil evidence, the study researchers said the shrinking of forests and expansion of savannas in East Africa led to walking upright, which freed our forebears hands up for the creation and use of stone tools. "Unstable...

Early humans were less primative than previously thought

Telegraph: Early humans were less primitive than previously thought, being able to carry out many of same tasks as man, such as making tools and adapting to the environment, researchers have found. Archaeologists had believed hominids like Australapithecus, which lived between four and two million years ago, were less physically and culturally advanced than early man. It was thought early species like Homo Erectus evolved long limbs, a larger brain and the ability to make tools to cope as the African...

Three simple reasons why climate change real & humans causing it
2014-06-23 09:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Conversation: Dire warnings of imminent human-induced climate disaster are constantly in the news but predictions of the end of the world have been made throughout history and have never yet come true. Even in the brief period of recorded history, natural climate change has always been with us whether it is the volcanically induced crop failures that helped precipitate the French Revolution or the Medieval Warm Period that allowed Vikings to colonise Greenland. So how can we trust that the computer models scientists...
SpaceX says it will put humans on Mars by 2026, almost 10 years ahead of NASA
2014-06-18 14:56:06| Extremetech
Elon Musk, speaking to CNBC about how the future of humankind is rather closely tied to our ability to get off this planet, is "hopeful that the first people could be taken to Mars in 10 to 12 years" -- with SpaceX rockets and spacecraft, of course. This lines up with some of his previous comments about establishing a Mars colony in the 2020s. Meanwhile, NASA recently announced that it would try to put a human on Mars in 2035 -- and only if it can secure the necessary funding and carry out a number of important milestone missions beforehand. Tantalizingly, Musk also spoke about SpaceX going public on the stock market -- perhaps to raise the necessary funds to fly (and establish a colony?) on Mars.
Florida Congressman: If Humans Cause Climate Change, Why Did The Dinosaurs Go Extinct?

ThinkProgress: A Republican lawmaker from Florida dipped his feet deeper into climate denial on Monday, saying it is "foolish" to believe humans can cause global warming, and justifying his logic with a strange comparison to dinosaur extinction. MSNBC host Richard Lui asked Rep. Jeff Miller (R-FL) if he was concerned about the fact that voters tend to believe scientists on the issue of climate change. Miller replied by saying scientists were not in agreement, and that the climate has been naturally changing...
