Genographic Project Informative Speech

The Genographic insure I. INTRODUCTION A. (attention grabber) Every 1 here in all samelihood knows what ethnicity you be, where your immediate family came from, or maybe stooge even phantom your great-great grandparents. save what if I told you that you can find out where your ancestors came from tens of thousands of years ago from development this (hold up a cotton swab) B. (thematic statement) Today I will be talking to you astir(predicate) The Genographic Project and what it has discovered in terms of ancestry. C. (establish implication/credibility) study geographic has been conducting the Genographic Project since 2005.Consider the following article illuminating Speech on African CultureThey have been collecting deoxyribonucleic acid samples from batch, and by studying and grouping the contractable markers pile possess, it can be obstinate which path your ancestors took when populating the world It can answer why we ended up where were are, and why there is a wi de variety of colors and features amongst worlds. promptly, what I am going to be talking to you round today is National Geographics Genographic Project only, because the scientific community has not know to a concensus that their findings are valid, and the have is still ongoing. D. preview of main points) (pic) So today I will explain to what the National Geographic Genographic Project is, how it is being conducted, what their findings are, and how you can be a part of it. transition But first, lets talk slightly what this Genographic Project is, and a micro about the science behind it. II. BODY A. (main point 1) In 2005, National Geographic Genographic Project was launched. a. According to National Geographic News. Com, Dr. Spencer Wells (pic)and a police squad of scientists are using technologies to uncover the truth of our genetic roots.They are analyzing patterns in DNA from participants worldwide that can tell us where we came from. He created the regard to further v alidate his previous research about where humans came from. on that point is great debate about where humans originated and the paths they took to populate the world. http//news. nationalgeographic. com/news/2002/12/1212_021213_journeyofman. html b. According to Genographic Project website, So lets survive into a little scienceheres how it works Fathers pass on Y chromosomes to their sons, and for Mothers and daughters, its different. Mothers pass mitochondrial DNA to their daughters, and their sons.This genetic code becomes varied by the generations through occasional mutations. When a mutation occurs, it becomes a marker that can be traced, and serve as genetic signposts for tracing evolution. Scientists, like Dr. Wells, can very follow markers through time and tempt the earliest ancestor for for each one marker. These markers in our genes can also help us to chart human migrations from Africa to other continents. The markers continue to split and split and you can eventuall y describe the root of all these branches to a common ancestor in Africa. ttps//genographic. nationalgeographic. com/science-behind/genetics-overview/ transition/with signposting Ok, Now we have an idea of what it is and the science behind it, lets recognise a spirit at How they are doing it and what they found. B. (main point 2) How it is being conducted- The Results they are finding. a. Dr. Wells and his team are obtaining DNA samples from ordinary people like you and me, and they are also traveling around the world to indigenous peoples and conventional cultures and obtaining DNA samples from them also.He is focused on obtaining very different samples of DNA to get the complete picture. https//genographic. nationalgeographic. com/about/ b. As can be seen in The human race Family Tree, (a documentary about this project), (pic)the team set up a carrell at a street fair in Queens. Imagine the smorgasbord they found in that one street that day. They took DNA samples from vario us people and contributed the samples to the project. (They did share their findings with the people who participated weeks later) (Movie source The Human Family Tree- National Geographic) . The Results are amazing. (pic) They were adequate to chart a road map of sorts to identify the roots that people took when they migrated out of Africa, by grouping the markers they found in the DNA that was collected. (talk about chart/map and how to identify the markers) https//genographic. nationalgeographic. com/human-journey/ d. They estimate that all humans springy today can trace their DNA back to a adult female who lived in Africa between 150,000 and 170,000 years ago. pic) She wasnt the first human, of course, but when you trace the markers in our DNA, it ends with her. That means that all other lineages have died out anterior to hers, and her genetic marker lived on and is in each and every one of us. http//www. oldthingsforgotten. com/dna/mtdna. htm transition /with signposting Ok, lets move on to how you can amount of money in too, now that we know what the results are. C. (main point 3) How you can help/ hook up with a. (pic) If youve got about $200 bucks, you can purchase Geno 2. Genographic Project Participation and DNA Ancestry Kit, in which you will receive these really fancy cotton swabs, and an envelope to return the results back to National Geographic. Lets not forget you can keep the box as a souvenir A portion of the proceeds from selling the kid goes back into the project for funding. You can then join their website, and your results will be posted there. You can also interact, if you upgrade your account, with various other people with the same genetic markers as you- Distant Cousins http//shop. ationalgeographic. com/ngs/browse/productDetail. jsp? productId=2001246&gsk&code=MR20936 b. So basically, what you can waitress to find out is which root your genetic markers indicate you traveled. (back to map)So in a sense, you will find out which hi ghway your ancestors took around the world. So for instance, (talk about African-American gentleman whos roots did not indicate what he thought it would). III. CONCLUSION A. (review of main points) So today we have well-educated about what the Genographic Project is, how it is conducted and what the results are.Plus we are all going to run slap-up to the nearest computer and purchase the kit, right? B. (reminder of significance) National Geographic has been submissive in documenting and researching all kinds of things around the world with respect to human and living organism populations, across the globe. This project is no different. They have the resources and the scientists behind the research to determine where we all came from. C. (dynamic closure) So I bet the next time you look at one of these (cotton swab), you will remember that it can used the bring the mystery about where you came from
