Last year, before she went on maternity leave, ABC anchor Elizabeth Vargas made a specialty of selecting stories on the sex-&-family beat. Vargas, substituting for Charles Gibson, stayed with familiar themes for ABC's closer from Ned Potter.
In December, Potter told us about a National Geographic TV documentary entitled In The Womb, which showed the fetal development of non-human mammals. On Sunday, NGTV will air Multiples in the Womb, showing how the embryos of human triplets behave, holding hands and kicking one another: "what happens when three brothers are growing at once," as Potter put it. "Incredible," Vargas murmured.
