50:00 National Geographic – In the Womb: Identical Twins

Utilizing highly advanced 4-D ultrasound imagery and painstakingly rendered computerized graphics, the film illustrates the processes that determine both the similarities and the differences between identical twins while they develop in the womb.

Born from the same fertilized egg, identical twins often share common physical attributes, social interests and personality traits. As shown in one of the many personal stories featured in the film, even those twins who are separated at birth can engage in strikingly similar life journeys. These common bonds are proof positive that the genetic make-up of the human species goes a long way in determining everything from the color of our skin to our sexual orientation.

The film’s revelations deepen our understanding of the human species, and show us that there is much we have yet to learn.
