"Anthropologist and National Geographic Explorer-in-Residence Spencer Wells describes his race to produce an invaluable genetic snapshot of humanity before modern-day influences erase it forever."
Stray thought after watching this.
Assuming that we move along the current emmissions pattern/world line to at least a PETM scenario by end of century, and assuming a Tainter Symplification with enough other species to hunt/gather/eat are left, would we in a rough and rocky manner become hunter-gatherers again, only to "rediscover" agriculture, 1 or 2 million years later at the end of the "long tail" of the warming, when we re-enter the dance of glacial/interglacial cycles?
