说得很好。根据发现的化石,可以推测出古猿生活在距今700万到800万年前的森林中。后来气候环境发生了变化,森林面积大幅减少,出现了大片的草原。那这时候古猿该怎么办?

Very well-said. According to the fossils that have been discovered, it can be inferred that prehistoric apes lived in forests from 8 million to 7 million years ago. Afterward, the climate changed. Forested areas significantly decreased, and vast grasslands came about. When that happened, what were the prehistoric apes to do?
