World's Largest Family Tree!


At-home genetic testing kits like AncestryDNA and 23andMe have become increasingly popular.  Geni.com is another heritage mapping company with over 130 million family tree connections worldwide.  Using these profiles, researchers were able to link 13 million people, possibly creating the world’s largest family tree.  How creepy is that?!

Europe: An Unexpectedly Close-Knit Continent



In research conducted by scientists in California, it was found that Europeans

are more genetically similar to one another than was previously thought. Using

genetic information obtained from 2,257 people across Europe, scientists Peter

Ralph and Graham Coop were able to ascertain that even people as far apart as

UK and Turkey share genetic similarities. This can be traced back to a group of

ancestors that many Europeans share. These ancestors came to the continent 6,500

years ago, which is earlier than previously thought. It is through these shared

ancestors in the not-so-distant past that Europeans across the continent are connected,

and considered “one big family.” This finding, however, is said by researchers to

not mean much in terms of peace between groups. For example, if anti semitic white

supremacists from one country find that they are related to Ashkenazi Jewish people,

it is unlikely that these Anti Semitic people will change their ways just because they

discover that they are related to Ashkenazi Jewish people.



















Although the findings of this research would prove to be surprising to some,

I personally am not surprised by these findings. I’ve heard the theory before

that everyone on Earth is related to everyone through five points of connection,

whether it’s through a friend’s family member, or a friend’s friend’s friend. I have

also heard that many people are the descendents of the Islamic prophet, Muhammed,

including the current queen of England. I have a friend who is a descendent of the

prophet Muhammed, and this would mean that he is related to the queen of England.

If my friend and the queen of England are so close in relation, I find it easy to believe

that the people of Europe are related to one another, and I find it understandable that

although these people are related, bad blood will likely not disappear. Bad relations

between family are easy to come by, after all.

Differing DNA Ancestry in Siblings

     You are taught throughout your life that "blood is thicker than water". Meaning that no matter what, your family will always be there. Because you are closer to them than anyone else in life. However, this may not actually be the case. According to recent studies, biological siblings may actually have less in common with one another than they might think. In one study two siblings, Kat and Evan Abraham, used a genetic ancestry test to determine their ethnic background. While expecting the results to be similar, they received the opposite in some cases. Kat was found to be 13% genetically related to Italy and Greece. While her brother Eddy was 23%. In another similar study, six  complete strangers had roughly the same genetic ancestry according to National Geographic's Geno 2.0 DNA kit.

     Biological siblings can have differing genetic ancestry based on a variety of reasons. DNA shuffle is the slight variations inside of an egg and sperm's DNA. This variation comes from the genetic recombination of DNA. After this shuffling of genetic material, the resulting sperm and egg have their own specific combination of genes. Meaning that each offspring will inherit slightly different DNA from each parent. One can take DNA testing with a grain of salt. As these genetic ancestry tests only compare the incoming DNA material with the samples in the database. And the majority of the samples come from North America and parts of Europe. Resulting in the data from other places to be less specific.

     I myself have a younger brother. This information makes me wonder how similar our genetic ancestry is. All my life i have believed we are incredibly similar. This newfound knowledge on genetic ancestry makes me question myself and the person I call my brother.

Family use of Marijuana:

There is a study being down that examines he familial aggregation of marijuana use, abuse, and dependence.  During the experiment, 2,546 individuals from 781 families were interviewed and the risk factors were calculated for each situation, and the data showed that for all three areas, the risk ratios were elevated in the family members of clinical pro bands. Meaning that the risk factor is transferrable from parent to offspring. This shows how some people are more prone to the addictive qualities of marijuana than others based off of their genetics passed down to them from their parents.

Heart Attacks Not Linked to Genetic DNA


It was always believed that heart attacks could be due to agenetic history of your family, studies now show that this is not a true fact. Researchers at the Intermountain medical center in salt city are discovering that heart attacks are not linked to family history.


Benjamin D Horne and his team studied many patients with different kinds of coronary diseases who did not suffer heart attacks.These patients were picked and identified by the research team by linking 700,000 patientsin a clinical data warehosue where family pedigrees are located. The research team had discovered that yes, coronary heart disease can be family gene associated but heart attacks are not.  Since cornary heart disease and heart attacks are so closely realted to eachother many people automatically believed that this trait would be inherited as well. Since this study began in 2008 it has shown that this is not true. The study was able to find out that only one genetic mutation was associated with heart attacks. This shows that heart attacks are rarely from inheritance of family members.

I think that this could be very helpful for a lot of people because many people believe that if someone in their family has a heart attack they are also likely to have one or be at risk for one. This study is very interesting and could be useful to many families who had a heart attack happen in the family.
