Your Inner Fish

Wednesdays April 9, 16 & 23 @ 10pm on HD

April 9 Your Inner Fish Our arms, legs, necks and lungs were bequeathed to us by a fish that lumbered onto land some 375 million years ago. The genetic legacy of this creature can be seen today in our own DNA, including the genes that build our hands and limbs.

 

April 16 Your Inner Reptile The show identifies some amazing connections: the amniotic sac was an innovation to keep our reptile ancestors’ eggs from drying out; our complex teeth can be traced to beasts that lived millions of years before dinosaurs; and our hair is linked to the whiskers of reptile-like mammals. 

 

April 23 Your Inner Monkey Our primate progenitors had bodies a lot like those of modern monkeys and spent tens of millions of years living in trees. From them we inherited our versatile hands, amazing vision and capable brains — but also less beneficial traits, including our bad backs and terrible sense of smell.
