DailyDirt: The Tree Of Life

from the urls-we-dig-up dept

Biology is a messy science. Nature doesn't lend itself to nice, orderly categories for people to understand. The tree of life is really tangled, and it's probably a bad analogy to start with. As we learn more about genetic analysis and find samples of ancient DNA, scientists are starting to reconsider some evolutionary processes. Here are just a few fascinating studies. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post.

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.

    is there an evolutionary tree for viruses?

    where do viruses fit on the tree of life?

    What about cataloging all the species before they evolve into new species? Remember, evolution is also about change, not just extinction.

    A Eukaryote has membrane bound internal structures

    Love your site, but some bio stuff is off once in a while(Like the Watson and Crick entry from last year). Eukaryote have internal compartments, like rooms, for specific functions/proteins. Bacteria, by your definition is a eukaryote(which it is not). Recently, bacteria have been found to contain microcompartments (Like eukaryotes except made out of proteins) however, they are not considered eukaryote as they lack lipid membrane bound complex structures. I'm tired so... Science*rainbow*
