Thought this worthy of a new thread. http://www.nature.com/news/controversial-study-claims-humans-reached-americas-100-000-years-earlier-than-thought-1.21886 Controversial study claims humans reached Americas 100,000 years earlier than thought Broken mastodon bones hint that Homo sapiens wasn’t the first hominin to get to the New World. Ancient humans settled in North America around 130,000 years ago, suggests a controversial study — pushing the date back more than 100,000 years earlier than most scientists accept. The jaw-dropping claim, made in Nature1, is based on broken rocks and mastodon bones found in California that a team of researchers say point to human activity. Their contention, if correct, would force a dramatic rethink of when and how the Americas were first settled — and who by. Most scientists subscribe to the view that Homo sapiens arrived in North America less than 20,000 years ago. The latest study raises the possibility that another hominin species, such as Neanderthals or a group known as Denisovans, somehow made it from Asia to North America before that and flourished.

Anything that ends in ology is open to interpretation and revision. Ology does not mean "the science of...", it means "the study of..." Includes Anthropology.

^^^ That's how science works, you form a hypothesis based on available data... and test it until new information invalidates it. No theory is set in stone, ever. --------- Very interesting finding, although I'm not too exited considering the hypothesis "is based on broken rocks and mastodon bones found in California that a team of researchers say point to human activity. " The researchers could simply be wrong, probably are if they're hanging their hat on such a weak link. It sounds like the global warming "hockey stick" hypothesis which was based on a few petrified tree rings analysis to deduce the historical climate data for the entire planet. It's a big joke today. The validity rate of new studies is pretty low after many eyeballs look at it... see http://retractionwatch.com/ yet the BF enthusiast in me hopes it's true.

No fire. Maybe they know an old trick to keep a baby happy and stop crying. You simply put a cantankerous baby lengthwise on your arm, kind of like you were going to let the little feller "fly" like Superman. They'll shut up immediately - and start taking in everything in front of them. Spread your hand across their chest, angle them up about 15-30 degrees, and that's how you can keep one quiet. Amazed at the number of parents who don't know that trick.

Arrived in North America 100,000 years earlier than previously believed, but only got to Central and South America in the last 20,000 years due to traffic in LA, probably...
