How age did the irish elk fail to adapt ice age?

There is no evidence to suggest that the Irish elk failed to adapt to the ice age. The Irish elk (Megaloceros giganteus) was a species of deer that lived in Eurasia from the Pleistocene to the Holocene epochs, and it is believed to have gone extinct around 10,000 years ago. The exact reasons for its extinction are still debated, but it is thought to have been a combination of factors, such as climate change, habitat loss, and hunting by humans.
