The Genus Australopithecus

Important skeletal fragments discovered in Africa have allowed scientists to reconstruct the history of the first ancestors of the human species: Australopithecus. These discoveries confirmed their ability to walk upright.

Bipedalism provided a significant evolutionary advantage, as it freed their hands to identify and collect food rich in protein and calories. While some features of this species resemble modern humans, other skeletal traits remain closer to those of apes.

A long process of natural selection favored individuals and groups that collaborated to secure food. The most successful groups retained mental maps of the landscape, organized to defend against predators, and improved their rudimentary tools. This...

Inca Architecture

The Inca architecture is the architectural style that was in effect during the Inca Empire, especially from the reign of Pachacutec Inca Yupanqui until the Spanish conquest (1438-1533).

The architecture developed in the Inca state was characterized by its simplicity of form, solidity, symmetry, and how its buildings harmonized with the landscape. Unlike coastal societies such as the Chimu, the Incas used a fairly sober decoration. The main material used was stone. In simpler constructions, it was placed uncut, but not in the most complex and important ones. Inca builders developed techniques to build huge walls, a mosaic of carved stone blocks that fit perfectly, without even a needle being able to pass through. Often these...
