Ice Age mammoths did not perish due to meteor crash but were killed by humans

#Mammoths #asteroidimpact #ClimateChange The generally accepted reason for the extinction of wooly mammoths and other giants of the Ice Age was due to asteroid or comet crashing on Earth millions of years ago. Woolly mammoths and other ice age giants may not have been killed off by an asteroid or comet impact.
Doubts have now been cast on this theory by archaeologists at University College London and the University of California. They have cast doubt on a major piece of evidence that is used to support theories that an exploding space rock was the culprit.
It had triggered an abrupt period of climate change at the end of the last ice age and discovery of melted droplets of rock and soil, known as scoria, that were probably scattered by the explosion could have killed the animals. But, the animals, in fact, died from fires that were created by humans.
The findings have questioned the old theories for what could have resulted in death of mammoths and other large animals other than by over-hunting by humans and changes to their habitat. Dr Peter Thy, a geologist at the University of California and lead author of the study, has suggested that there is no evidence as such that could point to the fact that siliceous scoria droplets resulted from very high temperature melting of soil and are the result of a cosmic event.
