Early human observing a supernova, illustration. Supernovae occurring during the early evolution of humans may have triggered such evolutionary changes as encouraging bipedalism. A global increase in wildfires linked to a supernova 7-8 million years ago led to an increase in grasslands, which in turn led to a need to not only see above the grass but to evade predators as well. | |
