Xin Xin, the last giant panda in Latin America, sits inside her enclosure at the Chapultepec Zoo, in Mexico City, Friday, November 11, 2022. Decades of study at the Chapultepec Zoo have yielded extensive knowledge, as well as genetic material – semen and ovarian tissue – that the scientists here hope will allow them to continue assisting in the pandas’ conservation even after Xin Xin is gone.
