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. After you've finished checking out those links, if you have some spare change (or more) and would like to support Techdirt, take a look at our Daily Deals for cool gadgets and other awesome stuff.

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.

–The Techdirt Team

    Er, typo?

    "our most recent common ancestor (MRCA) likely lived just 2,000-4,000 years ago."

    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?

      The human MRCA is based on a mathematical model and a lot of assumptions, but largely the date may seem far off because MRCA probably doesn't mean what you think it means.

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