On today’s Please Explain, Steve Bailey, Curator of Fishes at the New England Aquarium, and Marine Biologist and Chief Aquarist at the Monterey Bay Aquarium Michael Howard discuss why jellyfish are much more complex and interesting than scientists once thought.

Stewart Brand’s ‘Ecopragmatism’
In the 1960s, Stewart Brand became one of the country’s first and most famous champions of a new ecological awareness. His Whole Earth Catalog spoke to a generation of hippies and back-to-nature commune dwellers.
Now, at 70, Stewart Brand is calling on environmentalists to reframe their understanding of the problem — and solutions. It’s too late for back-to-nature, he says. Global warming is beyond that.
To survive now, Brand says, we need nuclear power, genetic engineering, giant cities. We must manage nature or lose civilization.
This hour, On Point: In the face of global warming, Stewart Brand redefines green.

Professor Christopher Dye: Are Humans Still Evolving?
Homo sapiens have been around for 250,000 years - surely long enough to have become fully evolved?
It was thought that the dramatic extension of life spans during the 20th century eliminated natural selection, but new evidence shows that to be false.
Will selection always be natural, or could postmodern also mean posthuman?
