- In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
I am so happy that I’ve worked under this brilliant man at national geographic !
I loved his documentary, “The Journey Of Man”. Just amazing. We are all one.
I have watched it 3 times on RUclips. Fascinating stuff.
really ahead of its time.
I'm glad to found his book by accident about last three days ago. Now, I am here to watch his speaking at TedTalk video. Though-provoking worth my time.
The role of citizen science cannot be trivialized. Trying to do science without it is trying to box with one hand tied behind your back. Scientists do not have the numbers to be able to do all the work, nor the brain power to do all the thinking. We must all participate in the process. This is one of the best argument for education of all of us.
I really enjoyed this talk. I find the whole story of human evolution and the human journey over the millenia endlessly fascinating. So glad that RUclips hqas this sort of contact. Just sad that the Geno 2.0 project has closed.
I can´t resist to this talks about genetic field, it´s explore our nature as humans and in addition to that we figure out so much about ourselves, it´s just one of the best things in the world with no doubt !!!!
I am from Ecuador and it is so amazing hear this really interesting conference.
Thank you very much for upload this video.
very good and informative lecture for common man
This man is my prophet for mankind being one family
I bought one of the Human Genome kits for my father. The results were quite interesting
Letter go! 2.0!
I LOVE GENETICS!!!
why??????
@@gwkqkqkkasmsmsmw2025 why not!?
I find this subject very fascinating. I did my dna and was surprised how much of a mutt I am. It makes you rethink about were you come from.
@Rising Sun
If the DNA could be submitted anonymously, would you still dis tie idea?
God works in mysterious ways. The people everyone hate are the original people of the earth ....made from the dust of the ground!
70,000 years ago, only 7,000 humans existed, because of a super volcano.
We are all closely related.
Start there!
(laughs in 2020)
"Facts" like that are quite often proven wildly wrong. The underlying data is sparse and based on very speculative assumptions.
Let's get this data on the Geode blockchain
I’d be interested in seeing the DNA results of Papuan New Guinea natives and Australian Aboriginal’s. I want to see if their the same because it was joined via a land bridge during the Ice Age.
What about US and Brazilian geneticists of Harvard have shown members of the Surui , Karitiana and Xavante peoples of Brazil's Amazonia region have distinctive DNA sequences that descend from earlier colonists called Australoids. They say these people left Africa 50,000 years ago are related to the Australia's Aborigines, the Onge People of India's Andaman Islands, and Papua New Guineans. Maybe it has something to do with the plant fossils found in the connecting southern reaches of land and in the same fossil plants found on the rock shores of Antarctica. During the Ice Age , a bridge could have formed the lands might have been closer. Connecting New Guinea to Australia and Tasmania was connected to Antarctica and along to the bottom of South America. The same Birch trees are still in all countries today Tasmania , New Zealand and Southern South America and the fossils of them are in Antarctica so the lands were connected. Maybe people migrated earlier than thought. And when the Ice Age thawed the lands were isolated and a second wave of people walked to Australia with Dingoes in canoes hence no Dingoes in Tasmania.
@@celticgypsy6067 Interesting. Future science investigations will advance our knowledge.
If you can find his Journey of Man documentary he discusses this with Australian aboriginals.
The more our cultures meld the better. Less ways to not get along and better communication.
lollollol.... funny guy, and amazingly informative
Voice volume goes from ten to two every sentence.
Why has the project stopped reporting Denisovan DNA to participants? is the estimate correct of the what had been reported?
Maybe it has to do with a new discovery that People with Denisovan DNA actually contain DNA from three very distinct groups of hominins that were related but only slightly more closely to each other than they are to Neanderthals. There is the northern group, where also the bones from Siberia come from, present in People from Tibet, Mongolia, Eastern Siberia and Northeastern China, the southern group, present in Pakistanis, Indians, Southeastern Chinese and Southeast Asians and a third group which was only detected in the DNA of Papuans.
It could be that they refine the testing for these three distinct genetic subgroups.
Thats my interpretation also. A Daily Mail article demonstrates the commonality of Neanderthal rendering many studies little value in isolation Denisovan ancestry. (You would capture this anyway)
Article "Neanderthals interbred for longer with East Asian humans, DNA reveals"
Daily mail you serious about this tabloid
Okay here's a question now that we can go back in time. How does the bloodlines tie into his research? If all life originates from Africa, and O is the predominate blood type. What mutations in the timeline evolved the 7 other blood types. Where does there begin a boom of the other blood types based on region, and cultural diversity? And what might have sparked the need for those mutations in the first place?
We barely even knew where we cane from until recently, good luck finding the answers to the rest of the at.
Trust me they are learning more everyday as the data base grows. I just sent in my autosomal dna sample to ancestry.com but first chance I get I'll be doing my geno 2.0 to find out my mtDna origins.
Please study to scientist, and find out the answer. Then tell us. :-)
watch a documentary by Alice roberts "the Incredible human journey" it explains some of ur questions
Climate,environmental changes, diet all played a part.
somebody knowledgeable in genetics or have participated in this project please help me out:
i wonder how they'd give results because every one of us each has countlessly many lineages. in the video they talked about only the mother's and father's side, but each side of parents have 2 different lines of ancestry and each of THEIR parents again have 2 different lines of ancestry and so on... so is there some way they can show this data in an intelligible way? or do they just talk about 1 of many many of those ancestry lines?
you'll get percentages of various dominant genetical lineages (for example" 14% nordic, 26% persian, 12% north african,...and so on)
@@ExploreLearnEnglishWithGeorge adding to your answer... Keep in mind that these percentages only apply to YOUR particular composition. Your full sibling might have slightly different percentages because they inherited different parts of your parent's DNA. So your results are just a piece of the bigger puzzle. The part that "belongs" to you.
They are basically saying which mutations you have. The mutations tend to have spread from certain groups at certain times. The assumption is that such mutations only occurred once. Thus, they are only connecting to you original source groups of mutations. They don't know which of your ancestors had the mutations (unless the mutations are on the Y-chromosome or the mitochondrial DNA, in which case the mutation completely followed the male line or the female line respectively).
Each of us has a unique maternal lineage: mom's mom's mom's mom's ... mom's mom and dad's dad's dad's dad's ... dad's dad. Thirty generations gets us to a billion ancestors.

What is the link to the DNA testing?
Does anyone knew here about Spencer's comment or explanation about the 700,000 year old butchered-rhino. I'm really curious about it.
That date sounds good for h. erectus. There’s good evidence for early humans butchering and consuming not only small animals but also animals many times larger than their own body size, such as elephants, rhinos, buffalo, and giraffes (whereas chimpanzees only hunt animals much smaller than themselves), thanks to their stone tools.

I'm a scientist, he's a good speaker, but I was disappointed in the general lack of scientific information and the overall commercial Aspect of the talk. Disappointing.
So i would like to see the Spencer Wells, 3 minute video, that basically says
here is the story,, apes,, people when 200,000 years ago,, when did the start moving, and
they were from Africa, you basically used a DNA marker instead of looking where people dropped their ash trays. , So the , show the migration, and what you know, because , the point is , like because of what you are doing, which could not have been done in the 60s, and the people to follow would not be not admixed in another some years so that is the point
1. There are no races 2 what we see is adaptations, in places where it is hot,, ,, 3 , can you trace that they came down through china, Korea and crossed to Japan and then got cut off to develop different cultures? I want the 3 minute video of Spencer Wells making that point and showing the map of the World that i can email to everyone , it should be required viewing in 6th grade, and 12 th Grade
So interesting. Love it
I was interested in the lecture until he went off on a side tangent / mini-commercial. Typical TED talk, broad overviews and little content.
Typical cynically comment vague offering no substance , just a smash and run comment ...empty ..
Keeping a Language from going extinct? I don't get it. I WILL happen at some time.
dammage no translate to french...
You can actvate subtitles to english, and then choose autotranslate to french.
@booklover Neanderthals only differ from us by 99.8% the difference is highly minor.
you meant to say they differ from us by 0.02% and are 99.8% alike..
yes i was using similarities not differences when calculating a mishap of an error.
Neanderthals of course are cousins of Modern Humans spring from the same hominid line just diverged at different times.
davidcici11Evolution 99.8 is “highly major” me thinks.
Adam and Eve ?!! Really?!
Adam and Eve yes but in a genetic way not in the biblical way.
All humans are related. We all have common ancestors. You and I have a common ancestor. It might have been 500 years or 5000 years ago.
All women can trace their mothers mother mother back to just one woman’s surviving lineage. There were other women living and having babies at that time but only that one woman's line was lucky enough to pass on her DNA to all women on Earth today.
The same goes for men. They can trace back their DNA to just one man.
Remember I'm talking about genetics. This wasn't two people mating and populating the world. This man and woman may have been separated by thousands of years. This is tracing ALL women or ALL men back to our earliest DNA ancestor. WOW can you wrap your head around that!!!! Just amazing!!!
This happened (I think) some time around 150 - 200 thousand years ago.
"Y Chromosomal Adam and Mitochondrial Eve"~
@Grady Whitman My comment wasn't on the validity of the idea, but do go on and explain how it was "deunked"
Grady Whitman What do you mean by non-human DNA?
@@beachbum200009 - You should clarify that you are referring ONLY to the mitochondrial DNA, not the nuclear DNA, which drives every single cell of the body except for the sub-cellular organelles called mitochondria.
So the alien Annunaki used a modern human ancestor evolved from Africa and added their own DNA to create modern humans. Makes sense since Ancient Sumeria is located close to Northern Africa. Just stirring the pot here. 😉
Michelle Despres you are definitely on the right track.. in my opinion
Seriously?
@@jaysteve4442 come on, you're joking ?
The Sumerian tablets, the Jewish Torah and the Christian Bible reference the same creation story.
Yep, a regionally popular *story*. :-)
So no talking snake? Let's face it if god made us, he did a bad job.
