Shapeshifting
There are old folktales and legends of people who can become animals. Animals who can become people. And there’s a lesson for our own time in those shapeshifting stories — a recognition that the membrane between what's human and more-than-human is razor thin.
Human identity cannot be separated from our nonhuman kin. From forest ecology to the human microbiome, emerging research suggests that being human is a complicated journey made possible only by the good graces of our many companions. In partnership with the Center for Humans and Nature and with support from the Kalliopeia Foundation, To The Best Of Our Knowledge is exploring this theme of "kinship" in a special radio series.
