Hello, listeners,
Today I released Carina Hoorn on the evolution of the Amazon Basin, just in time for Christmas for those of you who celebrate it and may appreciate some intellectual nourishment in addition to the gastronomic kind.
Finding outcrops in the densely vegetated Amazon basin is no mean feat. Carina has cultivated relationships with indigenous people there who have shown her where to find them. The result of her team's extensive research is a picture of great biological change starting in the Early Miocene about 23 million years ago when the northern Andes were undergoing rapid uplift. Erosion of the newly-formed mountains brought nutrient-rich sediments to the Amazon basin. Subsequent subsidence (related to flat-slab subduction under the west coast of South America) brought on marine incursions, with a consequent diversification of aqueous environments. The result is Earth's most biodiverse region.
I hope you enjoy listening.
Merry Christmas and a happy New Year!
Oliver
