In various cultures around the world, human identity cannot be separated from our nonhuman kin. The landscapes we call home — grasslands and forests, mountains and rocks, rivers and oceans — are shared by nonhuman beings who may be considered relatives. Age-old myths and modern science reinforce these kinship relationships. 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. Leading scientists, philosophers and writers illuminate ways in which “personhood” transcends the human species and shows how kinship practices can deepen our care and respect for the more-than-human world.
