Final answer:
The evidence supports the position that woolly mammoths became extinct due to changes in their environment.
Step-by-step explanation:
The evidence provided supports the position that the woolly mammoth became extinct due to the changes in their environment. As the ecology of the area developed into extensive forests of birch and conifers, the vegetation became less favorable for the mammoth and difficult to digest. Since the mammoths heavily relied on vegetation for food, the lack of suitable food sources led to a decline in the mammoth population in the area.
