Liu, Carbone, Brasier, Corfield, Wood - Ediacaran Marine Ecosystem - What scientists sound like.

Here are some more excellent videoed talks discussing the Ediacaran Period before I move onto the Cambrian Period in this Pageant Earth's of Evolution.  

The first is an presentation by Alex Liu, the sound suffers from some unfortunate interference, still the talk is well given and worth hearing out.  The second features Calla Carbone at 2016 Royal Tyrrel Museum speakers series, while she reinforces Liu's message, she also expands with further insights into early ecological community development and the varied environmental niches that appeared.  She's a bit nervous, but considering she was a newly minted Masters at this point, it's an outstanding talk.  This is followed by an audio of a fascinating BBC Our Time Podcast conversation hosted by Melvyn Bragg with guests Martin Brasier, Richard Corfield and Rachel Wood.

Mary L. Droser - Ediacara Biota - What a scientist sounds like.

There are many excellent videos about the Ediacaran Period in Earth's Pageant of Evolution - each speaker touches on aspects the others don’t.  It's what makes learning about this so fascinating, the endless surprises and aha moments.   
It's a reflection of the new appreciation that the dawn of animal evolution was way more complex and amazing than anyone imagined - that is, before the scientific evidence really started coming in these past decades.  No ID needed.  Makes me think I’ll be sharing a few more lectures focused on the Ediacaran before moving on to the Cambrian Period.  
This time I’m highlighting Professor Mary L. Droser because she does such a nice clear job of describing the variety and complexity that showed up in these oldest of creature communities.  Below the fold you'll find screen shots of key slides outlining her talk.
