Why do we have two eyes? Two ears? Two arms and two legs? Why is one side of the human body – externally at least – pretty much a mirror image of the other side?
CrowdScience listener Kevin from Trinidad and Tobago is intrigued. He wants to know why human beings – and indeed most animals - have a line of symmetry in their bodies. Yet, beyond their flowers and fruits, plants don’t seem to have any obvious symmetry. It seems that they can branch in any direction.
Anand Jagatia sets out to find out why the animal kingdom settled on bilateral symmetry as the ideal body plan. And it takes him into the deep oceans of 570 million years ago. Paleobiologist Dr. Frankie Dunn is his guide to a time when animal life was experimenting with all sorts of different body plans and symmetries.
Frankie shows Anand a fossil of the animals which changed everything. When creatures with bilateral symmetry emerged they began to re-engineer their environment, outcompeting everything else and dooming them to extinction.
Well... nearly everything else. One very successful group of animals which have an utterly different symmetry are the echinoderms. That includes animals with pentaradial - or five-fold - symmetry like starfish and sea urchins. And that body shape poses some intriguing questions... like “where’s a starfish’s head?” Dr. Imran Rahman introduces us to the extraordinary, weird world of echinoderms.
To answer the second part of Kevin’s question - why plants don’t seem to have symmetry – Anand turns to botanist Prof. Sophie Nadot. She tells him that there is symmetry in plants... you just have to know where to look! Beyond flowers and fruits, there’s also symmetry in a plants leaves and stem. The overall shape of a plant might start out symmetrical but environmental factors like wind, the direction of the sun and grazing by animals throws it off-kilter.
And, while the human body may be symmetrical on the outside, when you look inside, it’s a very different story. As listener Kevin says, “our internal organs are a bit all over the place!” Prof. Mike Levin studies the mechanisms which control biological asymmetry. He tells Anand why asymmetry is so important... and also why it’s so difficult to achieve consistently.

Ravi kicks off the show by reflecting on the final day of the DNC convention, how the past four days could impact Democrats’ chances against Trump in November, and the implications of Robert F. Kennedy Jr.’s pending withdrawal from the race.
Ravi then welcomes New York Times housing reporter Conor Dougherty to the show to discuss the current state of the housing crisis, how political dynamics influence progress, and why Obama may have decided to use his speech at the DNC to advocate for reform within the outdated housing market. Finally, Ravi and Conor delve into Silicon Valley billionaires’ efforts to create a new city in California.

Vice President Kamala Harris officially accepted the Democratic nomination for President Thursday night on the final day of the Democratic National Convention in Chicago. On a star-studded night that included appearances from Kerry Washington, Reverend Al Sharpton, and NOT Beyoncé, the energy on the convention floor was electric as Democrats anticipate the general election, less than 75 days away.
Harris’s speech included touching moments from her life story, remarks on the economy and the war in Gaza, and even a few jabs at former President and Republican nominee Donald Trump. “What a Day” host Juanita Tolliver joins us from the convention floor to tell us whether Harris’ speech met expectations and to give us an inside look at the excitement as the DNC comes to a close.
