Stone tools in India suggest earlier human exit from Africa

I wonder if the Toba volcanic eruption ended this period of hominid colonization of the India sub-continent?

Some researchers claim that the Toba event drastically reduced the hominid population to just a few thousand of our Homo Anthropophagus ancestors.

However, other researchers are claiming not to find a widespread extinction event among other animals or plantlife.

It has been my (unverifiable) opinion that there was a lot more migration via rivers and along coastlines with dugouts or rafts. And that was what made them vulnerable to a major volcano blowing off with concurrent tsunamis.

The coastline/riverine migration hypotheses are reasonable, not new at all, and very hard to support with solid evidence -- mostly because of changing sea levels.

As the article states, the Indian subcontinent is very poorly-known archaeologically. That's a great pity, because good look at the map shows that it's an excellent candidate for an eastward migration route.

As is so often the case, the operant phrase is "stay tuned."

#RRW: Toba blew at ~ 75ky BP, so much later than period in question.

Lack of fossils proves nothing. India is a hot, humid subcontinent FILLED with plants and animals that would have happily dined on whatever remains anybody or anything left after gettin' killed. Gettin killed was the usual fate of hominids,nins or anything animal or vegetable in that area of the world and is still so today. So fossils, if thay even exist, should be few and far between

So in that sense, those arrow/spear heads are the most significant find in the light of other similar finds. 385K yrs is significant. This also says that those humans invented almost NOTHING more of value for hundreds of thousands of years. This lends credence to the theory that we are a synthesis of a native species and an alien species bioengineered into WHO we are today. Such was probably done in a lab that is under the Persian Gulf, if it yet exists. As we go to space, we should try to find the other half of who we are. The truth is out there!

Out of Africa hypothesis is not science, it is a political doctrine masquerading as such.

Yes, genetic analysis is sooo political.
Get real.

You mean the same genetic analysis that Jews claim make them a "people".

The idea that life originated solely first in Africa takes more hits every day.

Jews are people.
Get real.

Once again, comments on an interesting article descend quickly into insanity and straight-up ignorance.

Yes, the bigoted comments are further proof to my assertion that the evolution of intelligence is a dead-ended failure.

Jews are people.
Get real.

Oh really? I thought it was a religion... Oh they are a people when convenient and a religion when not?

I guess this geneticist is a fraud huh?

Define failure? Failure of what? What does bigotry have to do with failure? Are lions bigots for viciously favoring their own feline genetics? Are they failures? Are Slave making ants failures for being bigoted towards their own species and enslaving their own "kind"? You ACTUALLY believe that intelligence was achieved by solely being a goody two shoes? You really are naive. You are just weaponizing words for political points, too bad you wield a limp noodle.

No, you are a bigot since you deny your own genetics. All humans are obviously a single species, unlike your contrived examples.

species is merely word and ill defined method of categorizing life.

Yet species exist!

What are you getting at?
What are you trying to justify.
You seem to want to split up humans into different species, why?

Species do not exist. The idea of speciation is a social construct created arbitrarily by "scientists" to measure likeness of organisms. You are deluding yourself if you actually think speciation is some sort of natural set in stone marker for seperating the relatedness of organisms to one another. I could argue that bees are actually an expression of flowering plants, but you would classify them as different life forms.

The real question then becomes, why are you opposed to humans being classified as being made of various sub species? The answer is most certainly related to emotional and political motivations. For instance you have Species: lupus (gray wolves); rufus (red wolves) yet they are genetically less diverse than many human populations. I really dont understand the mind games you play with yourselves. This is why speciation is a joke and should not be taken serious by any real critical thinkers.

Just because there is not some clear line that can be drawn between some species does not mean that a species does not exist, your logic fails.
Speciation happens gradually, of course there is no set in stone line, so what?
Different species, different life forms, call them what you want, they still exist.

You sure could try to argue that bees are actually an expression of plants, but you would fail.

You still have not addressed the reasoning behind the classification of wolves and even dogs as separate species. Yet humans are somehow immune to speciation despite being genetically more "diverse".

Because it is not true, science proves it. Why would I not oppose a false concept?

Yet humans are somehow immune to speciation despite being genetically more "diverse".

OK, I see your mistake.

Human genetic diversity is substantially lower than that of many other species and the out of Africa theory has been proven correct by genetics.

You said "Just because there is not some clear line that can be drawn between some species does not mean that a species does not exist"

This tells me and any real intelligent person that you are drawing the lines of species arbitrarily. Let me give you an example. Take the sun for instance. How do we define the sun? Do we define the sun by the extents of it's light? Or the extents of it's heat? No, we arbitrarily define the physical sun by the extents of it's plasma. You are in essence arguing where the fist begins and the hand ends. By the way "science" is never settled nor does it supply "truth", it only reinforces preconceived narratives in an attempt to furtively influence the conscious direction of perception.

Yet humans are somehow immune to speciation despite being genetically more "diverse".

OK, I see your mistake.

More genes does not equate to "greater diversity". It is the QUALITY of the genes not the number that counts. 25,000 vs 500,000. Wheat has 500k but for all it's "diversity" it sure doesn't stop the combine ( developed by the less diverse 25k humans) from harvesting their brethren lol.

Genetics and diversity are fool's gold at best. When you have science claiming that a single troop of chimps possess greater genetic diversity than the entire human population on earth, that statement should cause you to question the validity of the concept of genetic diversity as it is related to actual physical observation.

No, I'm talking about genetic diversity within a species.

You should question your sanity, there is indisputably more genetic diversity in chimps than humans.
Maybe you are confused with phenotypic diversity.

And? Is phenotype not a function of genetics? What exactly is your point? You are ascribing importance in an arbitrary manner, or worse yet , you are interpreting data to support a political or social narrative.

No, I just think he is terminally confused, full stop. There is also more genetic diversity within Africa than outside of it, which also points to an 'Out of Africa' scenario.

Everyone is terminal. At least I'm not deluded.

I disagree. As does the science.

This conversation seems to have become deluded with a UFO abductee called StevePidge from Alabama claiming that the low genetic diversity of humans away from africa is not the same as when he takes an african plant home from the garden center and claims that he is supplying the garden center with the african plants, even though they have 500 different colors of them and he only has a pot with a garden center label in it.

No one is charmed in your delusion StevePidge, it's like when mr nobody was taking my stuff in school. Steve still exists in mr nobody world... and he will take us all on if we say that mr nobody doesnt exist. END OF STORY. BYE STEVEPIDGE.

Just a week after scientists reported evidence that our species left Africa earlier than we thought, another discovery is suggesting the date might be pushed back further

Science has debunked that early humans came from Africa. Early Humans were White According to Latest Fossil Find by Scientists, Scientists Discover DNA Proving Original Native Americans were White etc...

Shall I start with the bigoted monkeys first? Alright here goes. Ahem... A Species is any group of biological organisms that can sexually reproduce within that group.

Otherwise all the whiny bigots wouldn't be raping every unprotected female they can catch. Otherwise it's bestiality. The very definition of bigot as a subhuman subspecies.

As the recent article on zebras pointed out. It was overly enthusiastic nineteenth century explorers and naturalist that insisted there were six separate species of zebra based entirely upon external features. And they were wrong.

It does not matter how many books or articles they published on the subject. Nor on how many professional awards and degrees were bestowed. Or how many public and academic lectures they gave extolling their conclusive findings.

They are now proven wrong through new technology and evolving procedures.

We should all consider this embarrassment before we claim we alone have the FINAL TRUTH!

And? Is phenotype not a function of genetics? What exactly is your point? You are ascribing importance in an arbitrary manner, or worse yet , you are interpreting data to support a political or social narrative.

You have it backwards again.
You can have very low genetic diveristy with high phenotypic variability, think domestication.
This happens due to pleiotropy.
Google "peliotropy" in relation to domestication, if you dare.

No, I think you have misunderstood. By the time they got to the Americas they may have been pale skinned. Not surprising given that they came over from Siberia. Europeans are light skinned, for the most part. However, the ancestors of the native Americans left Africa ~ 50 000 years before they got to America. And at that stage they would have been dark skinned.

And? What of it? Phenotypic variability is still just a physical observation of genetic change. What is your point? You keep making arbitrary distinctions. How are phenotype changes recorded? In the Genome. It's all genetic. you are like a barber who claims to be a "spit end" specialist that does not work on hair.

Key words here. MAY. 50,000 years lol. Even your dating systems are not capable of accurately determining age that long ago. 50,000 years ago is so long ago that it is impossible to know what happened or what takes place over such long periods. Yet we have all these "intellectuals" claiming to know and possess truth through their "scientific" study. Get real. Better yet, get a real job.

This is not even intelligible banter. You are quite strange.

Wrong. We can date rocks going back 4.6Ga. 50 000 yrs is a breeze.

Wrong. Multiple lines of evidence tell us when the most recent common ancestor left Africa.

Get real. Better yet, get a real job.

How about getting an education? You obviously know nothing about the subject. Just another Dunning-Kruger blowhard.

Jonesdave, you obviously feel insecure. You can believe any narrative you want. But dont expect anyone with half a brain to believe you can date anything. You are only able to read isotope decay, you have no idea if the decay rates are steady, nor do you know the original makeup of the rocks. Your rock dating is as accurate as Nostrodamus.

And? What of it? Phenotypic variability is still just a physical observation of genetic change. What is your point? You keep making arbitrary distinctions. How are phenotype changes recorded? In the Genome. It's all genetic. you are like a barber who claims to be a "spit end" specialist that does not work on hair.

See, you don't even get my point, you keep getting it wrong. Let me try again.
Phenotypic variability in a species has little to nothing to do with genetic diversity.
You cannot tell anything about genetic diversity in a species by looking at it, get it!
The only way is to look at the genetics, duh.

Who is this science? Where can i meet him?

This is not even intelligible banter. You are quite strange.

You are correct, this is beyond STUPID.
How can you have intelligent banter with someone who asks ridiculous questions like that?

You are obviously in denial and feeling insecure.
It is an impossible and thankless task trying to defend a position that had its foundations ripped from under it with the introduction of genetic sequencing.
Unfortunately for you the genome of a species is clear map of genetic changes through time and even if it cannot be precisely dated the basic cladistics are clear as a bell.

Wrong. Again. You are obviously not very well educated, so I won't go into huge detail, but one can, for instance, for relatively recent times, date a volcanic eruption. You can then have a look in the ice core data to check that date. You can also use different types of dating; say K/Ar, ESR, etc. However, like I say, this all seems to be beyond your pay grade, so you carry on believing whatever helps you sleep at night. Just don't forget, before you nod off, to say a little thank you to your (black) forefathers.

Once again you completely ignore your built in assumptions on steady decay rates and the original composition of the sample. Figures you would just ignore such a simple logical problem with radiological dating of all types. With argon especially it seems to me to be a certainty that water and gas will enter rocks through tiny cracks and invalidate almost all radiometric ages. I suspect your (black) forefathers did not bequeath you enough erudition.

It seems to you? Lol. I couldn't give a tupenny cuss what you think, you are an irrelevance. Link me to the science behind your baseless assertions. You're opinion is of no value.

Your self inflation means nothing to me, your spells are powerless in the face of truth. Ignorance is your commodity for you are poor of mind and wisdom.

And the truth hurts...

I've always wondered why we find Lascaux and the Venus of Willendorf in Europe but nothing comparable elsewhere on the planet til very much later. Anyone have thoughts as to why that seems to be the case? It strikes me as a glaring anomaly that I've not found discussion about.
