Depending on your religon (or lack there of) you probably have a belief of how we humans got to be on this earth.
What's your view on it?
Here's mine (based on a collection of reading over the years):
About 4 million years ago in East Africa a particular type of ape lived in the jungle. This ape was the prececessor of what we now call humans and chimps. The climate was changing in that part of Africa to be a lot dryer forcing some of these apes to begin leaving the trees. The ones that stayed became chimps. The ones that went out there mostly died.
They died because they couldn't see the lions and other nasties out there. But a handful of them figured out that if you stood on your hind legs that you could see further. Hence those lived and passed their genes on. As time went on, more and more of these surviors were walking up right. This was important not just because they could see further but they could walk further.
This freed their hands up to do other things and most of them were still dying to lions and other nasties. But some of them were bright enough to throw rocks and they lived, to pass on their genes. Repeat this cycle for 3.9 million years and you have homosapiens. Add some other birth defects in that pushed us alon gin having to obtain a variety of food that chimps don't (humans can't produce Vitamin C, we have to consume foods that have it) and only the smarter ones survived.
Around 60,000 years ago these homosapiens, for reasons I don't know, figured out how to communicate verbally. Perhaps it was a mutation (all humans have a birth defect that causes us to be unable to drink and breath at the same time, this allows us to make a lot more sounds than any other mammal - while we're not choking anyway). Once we were able to start communicating like this, ideas could be passed along and within 60,000 years we went from hunting and gathering to farming (around 8000 years ago) to where we are now.
So what's your view?
