I’ve mentioned before in Dynamic Earth about experiments to reactivate dormant genes in chicken embryos. The develop into rather dinosaur-looking creatures. This is pretty solid verification of the theory that birds are a development of dinosaurs.
Pick one of the articles, read it and write a one-page review, telling me about the article, what you learned and how you felt about it (was it well written, was it boring, etc.) Turn the assignment in when we return to school.
So Wednesday in Dynamic Earth I showed you two TED talks on oceans. The first is a very upbeat and hopeful view from Dr. Robert Ballard, the famed ocean explorer. He is a link to the talk if your interested.
The second video is more worrisome. Coral Ecologist Dr. Jeremy Jackson has seen massive ocean ecological destruction by the hand of man during his career and tells of a dark future, with a damaged ocean.
So I get home Wednesday night and who do I see on PBS? Jeremy Jackson. The new PBS show is called Earth: A New Wild. And looks at how humans are trying to effect a positive change on the environment by managing wilderness. Dr. Jackson and many, many others, are trying to regrow coral reefs, farm fish in the ocean instead of on land, introduce species that filter toxins from the water, and other amazing ideas.
Good show and you can watch it online. The episode I saw was “Oceans”
