Question

Woolly mammoths were grass-eating mammals that resembled elephants but with heavy coats, large tusks, and small ears that made them suited for extremely cold weather of the ice age. In addition to hunting by humans, which other conditions may have caused woolly mammoths to become less reproductively successful and eventually become extinct at the end of the last ice age? (2 points) Decreased grassland habitat size caused by a warmer climate
Decreased mammoth predator population size caused by warmer climate
Increased production of offspring adapted to the changing environment
Increased genetic variation in mammoth populations in warmer latitudes

Answer 1

Decreased grassland habitat size caused by a warmer climate

Answer 2

Answer:

The two points included here are options (1) and (2)

Explanation:

The Woolley mammoths have existed on earth upto the Pleistocene age and has significant decreased after that and by the end of Holocene, they were extinct.

This extinction of mammoths were due to the episodic global change in the temperature. Due to the rise in the temperature of the earth before the Pleistocene, the water level on earth decreased. As a result of which these organisms were affected including the mammoths. The environment was very hot that made it difficult to survive.

Again, during the Pleistocene age, ice age started and the sea level eventually rised. As a result of which the vegetation-covered areas were buried under the thick sheets of ice. It made them difficult to obtain their food from nature. Thus, it made them difficult to exist.

Hence, these are the two options that are responsible for the extinction of woolly mammoth species.

Therefore, the correct answer is option (1) and (2).
