The human journey-- a genetic odyssey: Spencer Wells at TEDxConnecticutCollege

[@thinwolf4516]

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 am so happy that I’ve worked under this brilliant man at national geographic !

[@suzanneengland8978]

I loved his documentary, “The Journey Of Man”. Just amazing. We are all one.

[@patrickwentz8413]

I have watched it 3 times on KZbin. Fascinating stuff.

[@zencat999]

really ahead of its time.

[@tupeauelua7197]

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.

[@JoaoVictor-dw2ci]

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 !!!!

"Facts" like that are quite often proven wildly wrong. The underlying data is sparse and based on very speculative assumptions.

[@BradleyLayton]

Let's get this data on the Geode blockchain

[@shahidparacha2367]

very good and informative lecture for common man

[@annettegustafson1435]

I bought one of the Human Genome kits for my father. The results were quite interesting

[@ladyphay]

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?

[@donteo508]

We barely even knew where we cane from until recently, good luck finding the answers to the rest of the at.

[@ladyphay]

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.

[@gagarinsspray982]

Please study to scientist, and find out the answer. Then tell us. :-)

[@thisbishawesome]

[@delgadojonesable]

Climate,environmental changes, diet all played a part.

[@celticgypsy6067]

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.

[@celticgypsy6067]

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.

[@gagarinone]

​@@celticgypsy6067 Interesting. Future science investigations will advance our knowledge.

[@squarebear619]

If you can find his Journey of Man documentary he discusses this with Australian aboriginals.

[@janedoe1146]

Why has the project stopped reporting Denisovan DNA to participants? is the estimate correct of the what had been reported?

[@obiwahndagobah9543]

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.

[@duckvenom]

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"

[@lonestarx4439]

[@nicolasfuertes8793]

Does anyone knew here about Spencer's comment or explanation about the 700,000 year old butchered-rhino. I'm really curious about it.

[@aleanbh3808]

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.

[@iranjackheelson]

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?

[@ExploreLearnEnglishWithGeorge]

you'll get percentages of various dominant genetical lineages (for example" 14% nordic, 26% persian, 12% north african,...and so on)

[@gitanafox9852]

@@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.

[@bruzote]

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).

[@BradleyLayton]

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.

[@razorgg]

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

Adam and Eve ?!! Really?!

[@beachbum200009]

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.

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.
