I suggest you read more of that first link than just the headline.
Can't C/P from it but it goes on to tell that it's not a bad thing, for instance, that the smaller brain that survived evolutionarily is more efficient without the need for size.
This proves..what? That evolution is going backwards? That it disproves evolution because something is happening that shouldn't? That our braisn are becoming more efficient, perhaps by increased folding, improved neurons, or less wasted space thinking about the footling claims of religion?
Kitty, I never said anything about Creation-ism in my posts of this thread, nor are
the phrases or links I posted from creation-ist websites. You may feel free to copy
and paste the sentences into your search engine of choice.
Oh per-lease, don't be faux -ingenuous. The swipe at Radiometric data, the creationists source and the pointer to RATE trying to discredit deep time in hopes to keep YECreationism afloat makes it pretty clear what your last attempt to prove that evolution isn't happening (in fact brain shrinkage tends to show that it IS ) shows clearly enough what your agenda is, even if you don't actually type the words.
P.s the way we work is, the burden of proof is on the one making the claim. It is NOT for us to scamper off and find your sources, evidence and argument for you. YOU do that yourself. We then have the job of refuting it, if we can.
People have overlooked the very small human population for most of our history. Pulling from WikipediaWorld population - Wikipedia, the free encyclopedia, the total number of humans in existence only 35,000 years ago was about 3 million.
It was presumably much less for most of human existence. In addition to a lack of knowledge upon which to build and lack of educational institutions to pass along the knowledge, there were simply not enough people with leisure time to develop additional knowledge. If all of your time is spent hunting, gathering, tanning furs and chopping wood, you simply aren't going to spend a lot of time in the evening developing mathematical techniques.

Even if it is less efficient, shrinking brains would be an example of evolution. Evolution is a change over time, and decreased brain capacity is a change. Evolution does not necessarily provide advantages, and it is a fallacy to think of any creature as being more advanced or superior to another.
As an example, we are certainly smarter than insects, but there are a lot more of them than there are humans. If evolution is a contest, we are losing in that respect.
and no-nothing can't explain from single cell to human in 500,000,000 years. Thats fast. Thts 1/28 the time from big bang to human. dat real fast. Let alone from single cell to human in 10 months.
That's because your claim is predicated on fantasy.
The first organisms with a nucleus appeared about 1.75 Billion years ago.
That's 1,750,000,000 years and not the 500 Million years you claim.

I'm just speculating that perhaps for the first 90,000 year (if you have a different time line fine by me) the tribes either didn't see the long term values (cost versus benefits) in agriculture. Or perhaps though the idea of sitting around waiting for a crop to grow was risky business. Basically our ancestors might have thought of agriculture before 10,000 years ago. But thought perhaps their current ways of doing things had proven successful enough as to not wish to risk the tribes continued survival on this new lifestyle.
Of course there is the important technological issue of figuring out how to store abundant crops for leaner times that also probably was an important issue that may have inhibited the agricultural lifestyle.
But that's just my 2 cents.
What?
C'mon people, think.
See that?
That's how your world really is.
Only worse.
90% of the time, Earth is just like that map.
The Glacial Cycle is akin to your Sleep Cycle.
Imagine waking up at 5:00 AM, and everything is covered in several feet of snow and ice. You go to bed later that night at Midnight, and the snow and ice melts over the next 2 hours. For an hour while you're sleeping, it's warm and mild and delightful outside. Then for the next 2 hours, it starts getting frigid cold, and when you wake again at 5:00 AM, everything is covered snow and ice.
What you are experiencing now in terms of climate is unusual, abnormal, uncommon, atypical, deviant, irregular, anomalous, and whatever other synonyms exist.
Having said that, let's talk about the Mini-Ice Age.
In 1685, there's near-famine conditions in the New England Colonies, because of the Mini-Ice Age.
Your growing season is 6 weeks. You got 6 weeks to plow your fields, plant your crops, grow them, and harvest them, before you lose them. In the region that is now between Interstate 80 and just south of Interstate 70, the growing season was 10 weeks from about the 1st week of June to the 2nd week of August.
Why?
Because the ground was frozen until the time it unfroze.
The soil is frozen; you can't plow; and you can't plant. You have to wait until the first couple of inches that's out before you can plow and plant, and then the first frost in August will kill everything.
It was horrible in Central Europe, mostly Scandinavia and what is now Germany and Poland.
Millions of people died of starvation or starvation-induced diseases.
Let's jump back.
The period 25,000 BCE to 18,000 BCE shows evidence of cannibalism. Conditions on Earth were so bad, that humans restored to eating other humans. Were humans killed to eat, or did they simply eat the dead? That's unknown. However, a number of sites dated to that period show human bones with markings and scrapings, plus having been cracked open to get the bone marrow.
You can imagine the conflicts between groups as they competed for what few food resources were available.
Again, I refer you to the map. Those are glaciers, not snow.
Human habitation was effectively limited to the region between 30°N and 30°S of the Equator.
The ability to cultivate crops requires security and stability. You don't have that until very recently.
Most of your crop domestication takes place around 14,000 BCE to 13,000 BCE. Between 18,000 BCE and 15,000 BCE would be the transition from the Glacial Period to the Post-Glacial Period, when global temperatures began warming.
What will you do when the Pre-Glacial Period begins anew?
Nobody knows when that will be. It could be now, or the next few thousand years, but it will be soon (in terms of geologic time).
Pre-historically...

Mircea. I didn't say climate didn't play a major role. I was adding in a possible psychological element to the equation as to why we have been only farming (consistently )for the last 10,000. Relax dude.

Everyone seems to be ignoring the evidence we have cast in stone all over the planet, of advanced civilizations that pre-date our known history.
Ignoring also the wars and destruction, described in religions far older than Christianity.
Nonsense. There really isn't any evidence of previous advanced civilizations. Where are the mines? The nuclear waste deposits? The evidence of plastic in the environment? We are an advanced civilization and we have changed the planet in ways that will be detectable for hundreds of thousands of years.
I don't believe you even said that, the lists are virtually endless.
