DailyDirt: What Are We Going To Do With All This Genetic Information?
from the urls-we-dig-up dept
Genomic sequencing is becoming more readily available and cheaper by the minute. It's not quite as easy as it looks on TV (ie. we don't have a Star Trek tricorder just yet), but minuscule amounts of DNA are revealing a vast amount of information about our health and our ancestors. This treasure trove of data is literally lying around everywhere just waiting to be collected.- The genetic information of 2,636 Icelanders has helped researchers more accurately pin down when the father of all humanity lived -- some time between 174,000 and 321,000 years ago. Our mitochondrial Eve is estimated to have lived about 200,000 years ago. However, our most recent common ancestor (MRCA) likely lived just 2,000-4,000 years ago. [url]
- A routine blood test can determine the sex of a baby just 7 weeks into a pregnancy. Can we expect people to use the results of these tests responsibly? How accurate do these tests really need to be? [url]
- A diagnostic test for cancer based on a simple blood test could save a lot of time, money and stress. The Lymphocyte Genome Sensitivity (LGS) test is still in clinical trials, but early results suggest it might be possible to detect cancer or pre-cancerous conditions without requiring biopsies. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Er, typo?
Considering Jewish people can all trace their ancestry back at least 2500 years, I'm guessing that an MRCA is probably further out than that, no matter how many children Ghengis Khan had. Even 4,000 years is pushing it, but is somewhat more believable.
I can see some problems if our Eve was 200,000 years ago and our Adam was off by even 100 years as well... unless people used to live significantly longer lifespans.

Re: Er, typo?
Your "Adam" and "Eve" present absolutely no problems at all, however. Why would they have to lie anywhere near each other in time?
