Sudden heat spikes did in Ice Age’s mammoth mammals

Rapid climate change put mega-sized Ice Age mammals on the ropes before ancient humans delivered the final blow, new research indicates.

During Earth’s last glacial period, around 12,000 to 110,000 years ago, woolly mammoths, sedan-sized armadillos and other massive mammals walked the land. Over time, these megafauna mostly died out. The instigator of these extinctions has become a topic of heated debate among scientists, with fingers pointed at both ancient humans and sustained frigid temperatures.
