Question

Scientists have found two leaf fossils that come from very different climates. The smooth-edged leaf is from a warm climate, and the toothed-edged leaf is from a forest in a cooler climate. If the toothed-edged fossil was found in the desert, what hypothesis could you draw from this information.
The climate changed from cool forest to hot desert.

Answer 2

Answer:

The first one has to be the answer

Explanation:

If the area had once been covered by ice or snow, then there would be no place to get the warm leaf from.

If the area was once underwater then I don't know how it would have grown a cold forest, a tropical forest, and then a desert.

It'd make more sense if you started with a cold forest with sharp leaves, that slowly became a warmer forest with smooth leaves, only so it could become a dessert with only leaf fossil remains.

so ya the first one is your answer.
