Why do scienctist think the ICE AGE encouraged people to move around the world?

Was a good program that answered part of your question on BBC 2 last week...not sure when it will be repeating but it's worth looking for...it was on our U.S. Discovery channel yesterday.  The driving force seemed to be food as other post have stated.

so it would be faster to travel. and also so it would be easier? and it can get across oceans faster. and humans have wanted to fly from the beginning of time.

what do you think they are billions of tons moving across material mostly softer than the Glacier so they grind ,away mountains and soils and anything in the way ,\nthe titanic was no match for just a minute piece of ice ,\nclaciers are a hundereds of times bigger,they also carry huge rocks with them which do a bit of grinding on their own,\nin some parts of the world .like the high veld in South Africa the land got its shape by huge masses moving over them.

I dont think the early map makers were the ones thinking the continents moved.. \n\nI think it was geologists who discovered the tectonic plates and how the earth's crust is moving, then they analyze ancient rocks from two continents and compare them, if they are the same then they must come from the same continent

they kept moving south, away from the ice. They were following the food.  So improvments in hunting helped them branch away from the demanding path of the mammoths.  Then, fire and the wheel, basic I know, but they needed to get far enough south to avoid the ice, OR skin the animals for their most valuable fur.

Cold weather is the result of non-will in us. If none of us step up and start Being that which we really are, then maybe an ice age will come. I live in Sweden, and yes it is getting colder.....

actually we saw a movie about this in science, we will not be alive because there will be an ice age that happens in cycles. think about it, we will not last because we do bad when it is only 30 degrees f outside. plus, 1 million years is not that long for evolution compared to the eras is the past ex precambrian was 3900 million years long.

It's full of lies. Keep in mind, this is the same person who predicted another ice age in the seventies...sorry, i really don't believe in global warming until i get some real facts. After all, how do you think the glaciers melted? The earth had to warm...and that was long before SUV's were around. just my thoughts.

No, becasue, if you ever watch old shows from the 70's.. they were all hyped up that there was an ice age coming. odd how we suddenly changed it into global warming? yes.\n    if you actually study charts of the history of our planet's heating and cooling over time, its quite normal for earth to heat up and cool down by a few degrees over a couple hundred years. \n    do you know where the big concern is? 1.5 degrees on average. Over 200 years. of course a BIT of it might have been influenced by the coming of the industrial revolution, but as already mentioned on here, volcanoes etc give way more crap into the atmosphere than we ever did. and besides.. with all the tree huggers etc businesses arent allowed to put nearly as much gas into the atmposhere as before. we're almost cleaner than before the industrial revolution. we dont use coal furnaces... everything is cleaner on the whole. \n       and also.. i always find this funny...if you look up the past ice ages... you'll notice how the tempurature rises for a time steeply.. then plunges. i forget the interval of years exactly... but i do know we're ready... and guess what? then temps rising. i'd be moving towards the equator, not the poles in coming centuries. \n\n      besides... how could ppl make money in the news etc if they didnt make a big hype about something so non-effecting as global warming? they should at least get their information straight and threaten us about an ice age. then maybe you can beleive them.\n\nif all else fails people... DO YOUR OWN RESEARCH! dont trust what everyone else says. you cant even tell where the facts are coming from.

Totally agree. although I do believe in the spirit world.\n\nDue to freak weather that can happen in that region there was a sheet of ice on the river that moses parted.  He basically cracked the ice with his staff and it split.\n\nAlso Jesus walking on water was him probably walking on ice.\nOther stories can be explained in a similar manner without the disciples deliberately telling lies or being brainwashed.\n\nJesus in the speak they used during that time to me referred to our sub conscious mind.  Which is obviously a part of evolution and has developed for centuries.  We can probably tap into information that floats around like micro waves radio waves etc we cant see them we just need to try in tune in like mediums do.

dude educate your self before you make a broad statement like that. please dont be ignorant. in my opinion is it doesn't exist. because think about it we are coming out of an ice age. it makes sense doesn't it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinosaurs piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in Minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glaciers, etc. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freeze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in Texas and it would only be as densely populated as NY city). so our vehicles and combustible engines couldn't have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasn't but it was because of the CFC's(chloral floral carbons) which broke up the ozone by attaching to ozone molecules. but the CFC's are no longer around. the ozone is healing itself as it is meant too. their was no real hole only a thinning which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isn't that much and while the earth was cooling after being created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here doesn't mean that the earth will stop having ice ages as it has done by its self for billions of years. think about it. am i a genius or what i mean i just looked at what has happened in history wow who would have thought history would repeat its self

no thats wrong. you want to look up the Milankovitch theroy of excentricity of orbits. he said it goes in 40,000 to 100,000 year shifts between 22.5 and 24 degrees.  If the previous answer is right we would have a global ice age every 6 months.  and it would be NOTHING like winter in the N.Hemisphere.  sea levels globallly would rise and fall by hundreds of meters every 6 months. basically we would be dead.

The currently-favored theory has to do with Milankovitch cycles:  periodic variations in Earth's axial tilt and orbit that cause it to oscillate between cold and warm epochs.  \n\nThe theory seems to work well, but it has some holes; it can't explain all the ice ages of the past million years, nor why most of the planet's history has been ice free with only a few glacial periods.  In short, there's a lot we don't know about what causes ice ages.

actually, because of Global Warming, we would be in the ice age.  The increase in temperature causes a higher density of water vapor in the air, as a result the net temperature on the surface of the earth drops, and we get lots and lots of percipitation.  The Earth is making drastic attempts to shift it's self to remedy this.  Al Gore thinks we can control it because WE caused it, and so it would stand to reason that we fix it.

Depends on how you look at it..we seem to be in the effects of global warming..that does mean that the planet as a whole is warming up... but there are areas..where..global warming means more severe temperatures and weather as well..it certainly is hard to tell what the planet is doing on its own and what exactly we as humans have done to cause changes..I would say nope we are not near another ice age..it really wasn't that long ago that we did have an ice age..

Well I think it is because God was roaming the earth. There was no war, there was no sickness, there was peace and that's why people back then lived a lot longer than they do now. :)
