But instead, the rough climate and the vegetation changes seem to have encouraged some of our ancestors to become meat eaters.

Periodic corrections to the map may be necessary, typically vegetation changes in forested areas.

Long term studies on the dynamic processes of vegetation change continue.

These can provide clues to past precipitation, temperature, and vegetation changes over the last 500,000 years.

They come from a region with a continental climate where the proposed vegetation changes had not (yet) occurred.

The vegetation changes as going up and down these mountains, but the Pine forests are predominant.

As the vegetation changes, the wildlife and birds will also change.
