How did the changes in temperature lead to evolution of early man? |
|
Answer» All organisms encounter some amount of environmental change. Some changes occur over a short time, and may be cyclical, such as daily or seasonal variations in the amount of temperature, LIGHT, and precipitation. On LONGER time scales, hominins experienced large-scale shifts in temperature and precipitation that, in turn, caused vast changes in vegetation – shifts from grasslands and shrub lands to woodlands and forests, and also from cold to warm climates. Hominin environments were also altered by TECTONICS – earthquakes and uplift, such as the rise in elevation of the Tibetan Plateau, which changed rainfall patterns in northern China and altered the TOPOGRAPHY of a wide region. Tectonic activity can change the location and SIZE of lakes and rivers. |
