Atapuerca, the great discovery - PAU inglés Andalucía 2013 resuelto

>Exámenes selectividad inglés resueltos Andalucía


Atapuerca, the great discoveryToday’s society has a deep interest in the origins and evolution of our species. Scientists have come a long way since the discovery of the Neanderthals, more than 150 years ago. They now have much more complex theories in which genetic studies play a central role.
We can certainly situate our ancestors in Africa and relate them to other primates from whom they diverged about 7 million years ago. This evolutionary process was marked by the physical signs of adaptation to climate and environmental changes: upright position and mobility based on back legs, which freed arms and hands. But the most important adaptation was the change of their brains, which grew and became the body’s main energy consumer. With roughly a 600 cm3 brain, this Homo habilis developed the ability to produce simple tools for the first time in the history of humankind. After many repeated experiments, another ancestor, Homo ergaster, whose brain was probably around 1000 cm3, began to make sets of symmetrical tools called “bifaces”. The production and use of these tools constantly reinforced their cognitive skills. They were also able to create artefacts composed of different materials by using different techniques. All this finally led to changes in their social organization.
The best evidence of human life from more than a million years ago has been discovered in Atapuerca. Several species have been reconstructed thanks to the remarkably good state of the unearthed human skulls and bones. They have been used as a basis for studies on human evolution. However, two things remain unclear: how they migrated and extended throughout the different areas and how they communicated.
