"Evolution" is the eighth episode and mid-season finale of the ninth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on November 25, 2018. Plot Daryl, Jesus, and Aaron follow a missing Eugene's tracks. They observe a herd of walkers milling around in the middle of a field and talk about how unusual it is of the walkers to be doing this, and decide to walk around it.
