Question: why did saver tooth tigers extinct?

There were lots of different species of sabre-toothed cats, and they probably all went extinct for various reasons – their habitats changed, or there was a natural disaster – we don’t know all the details. However the most famous sabre-toothed cat has the scientific name Smilodon, and lived up until about 100,000 years ago in North and South America. Scientists think that it went extinct from one of two causes. Firstly, it could be that it went extinct when the last ice age finished and so the environment changed. But this isn’t sure because it would have survived other ice ages coming and going before that. Secondly, and possibly more likely, it went extinct because humans got to North and South America, and killed it off either by hunting it or by hunting its prey so there wasn’t much food for it.
