These results could inspire social and nutritional guidelines that would lead to the optimization of physical growth in children and maximization of the genetic potential, both at the individual and national level.Only in exceptional cases can significant changes in landforms or landscape be observed directly; field experiments at real world scale are notoriously difficult to conduct.Some regions have been cooling for decades at a time.And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.According to Flood (2004), about 50 species of large animals, the megafauna, including marsupials, reptiles and birds, went extinct in Australia in the last 100,000 years, about 41 going extinct in the Late Pleistocene.

(AB ev)Purnululu National Park: The sandstone formation of the Bungle Bungle ranges is estimated to be 350 million years old, give or take a few millions.

The aim of this study was to identify the most important variables determining current differences in physical stature in Europe and some of its overseas offshoots such as Australia, New Zealand and USA.

We collected data on the height of young men from 45 countries and compared them with long-term averages of food consumption from the FAOSTAT database, various development indicators compiled by the World Bank and the CIA World Factbook, and frequencies of several genetic markers.
