In a recent publication of a landmark study where 40 species of birds DNA were sequenced and cross compared some really illuminating findings about probable evolutionary reasons for specific traits and relationships were revealed. One of the most interesting things is what was not realized about the origins of the birds beak. " Although birds are descended from dinosaurs, they have no teeth. Most previous studies have suggested the common ancestor of modern birds lacked teeth, but other work has disagreed. The new findings add support to the idea of a toothless common ancestor, because all birds sampled share some mutations that turn off five genes for building teeth. Researchers estimate that teeth, or at least enamel-covered teeth, disappeared about 116 million years ago in the ancestry of birds. They suggest beaks replaced teeth in a two-step process. But it's still not clear why beaks took over for teeth, said study author Robert Meredith, a biologist at Montcl...
A chronicle of the things I find interesting or deeply important. Exploring generally 4 pillars of intense research. Dynamic Cognition (what every one else calls AI), Self Healing Infrastructures (how to build technological Utopia), Autonomous work routing and Action Oriented Workflow (sending work to the worker) and Supermortality (how to live...to arbitrarily long life spans by ending the disease of aging to death.)
