Within the genus Homo, cranial capacity again doubled from H. habilis through Homo ergaster or H. erectus to Homo heidelbergensis by 0.6 million years ago. The cranial capacity of H. heidelbergensis overlaps with the range found in modern humans.
The original height of the Pyramid was 146.5 m (488 ft), but today it is only 137 m (455 ft) high, the 9 m (33 ft) that is missing is due to the theft of the fine quality white Tura limestone covering, or casing stones, for construction in Cairo. It is still the tallest pyramid.
Cairo at 75 m/ 244 ft has a subtropical hot desert climate (BWh). Average temperature in Cairo is 21.4Â°C/ 25.2Â°F Rainfall 26mm/ 1in across 12.5 days. See graphs, tables, comparisons, more.
