Human Evolution: From Hominids to Homo Sapiens
**Hominization: The Evolutionary Journey to Humanity**
Biological anthropology defines hominization as a process of humanization. Changes promoted by the evolution of animals have allowed the emergence of the human species. The process began with the appearance of:
- Bipedalism: A factor that differentiated hominids from other species.
- Encephalization: A determinant of the occurrence of the genus Homo.
Hominids
The first phase is defined by the appearance of the family of hominids. The African continent

Decolonization
Causes:
- The weakening of European powers after the two World Wars.
- The existence of indigenous elites: The metropolises had created colonial cultures and enriched a minority of future leaders that emerged from decolonization.
- The role of the U.S. and the USSR was instrumental in supporting the decolonization process: Both states provided ideological, political, and military support. Decolonization weakened the European powers and helped consolidate the new order led by the two superpowers.
Contract Law: Essential Elements, Types, and Sales Agreements
Contracts: Definition and Key Elements
A contract is formed when several people agree on a declaration of common resolve to regulate their rights. A convention includes any expression of intent; it is a generic term. A contract, however, is a convention that aims to create property rights and duties.
Elements of Contracts
Contract elements are classified as:
- Essential: Indispensable for the existence of a contract, such as capacity, consent, object, and, in some cases, form.
- Natural: Implicit but can
Nihilism: Active vs. Passive and the Death of God
Nihilism: A Disease of Western Culture
In the Nietzschean conception, nihilism is not a theory but a way of life, a way of feeling and acting. More strictly, nihilism is a disease. It is the broken line of Western culture from Socrates until now. As Heidegger says in the Introduction to Metaphysics, nihilism is the destruction of the earth and of man’s gregarization. We call “nihilism” the unhappy consciousness and lack of ability to create that characterizes Western man. We are all immersed in the

The Nature of Light
The nature of light has always interested humankind. Scientists, philosophers, and thinkers have attempted to answer seemingly simple questions, such as “What is light made of?” since the oldest civilizations. Science, particularly physics, has no simple answers to these questions. For example, to answer that light consists of photons does not respond unless one agrees on the meaning of the word photon. A photon is not an object that belongs to our ordinary experience, like a

Military Uprising and Internationalization
The Military Plot
The coup plot against the Republic was born on the day of the February elections. The organizer and director until July was General Mola. The plan consisted of a simultaneous delivery of military garrisons, with Madrid and Barcelona as keys to success. In reserve was the African army, under General Franco. The supreme leader who should lead the uprising was General José Sanjurjo, in exile in Portugal, and respected by all managers. The

Item 1: Methods in Social Science Research
In the epistemological realm of the Social Sciences, there is no single rigorous, detailed, universal, and manual-like scientific method. The purpose of investigating the Social Sciences is complex, changing, and subjective, encompassing both society and the individual. There are multiple and different scientific methods to seek an approach to social reality to be measured. The methods of sociology are not interchangeable and random but are appropriate in

Formation of Rocks
Rocks are formed through various processes:
- Cooling of magma
- Disintegration, transport, and deposition
- Precipitation of inorganic salts in water
- Condensation of gases containing mineral particles
- Deposition of animal and vegetable remains
- Partial or complete recrystallization of minerals in a rock due to high temperatures and pressure
In short, igneous rocks are formed by the crystallization of magma. These rocks may be basic, acidic, or intermediate, depending on their composition, and

Product Attributes and Dimensions
In any company, the product is something that is produced or sold in the market. However, from a more market-oriented perspective, the product is not only a series of physical and technical characteristics, but rather a set of utilities that the client appreciates. Generally, a company does not sell a single product but a set of them, which is called a portfolio or range of products. A range of products can be composed of one or more lines of products.

Ideological and Political Evolution of Franco’s Regime
After the victory in the Civil War, which spread to the whole of Spain, a state was established whose foundations had been laid in the “nationalist zone” during the conflict. These can be summarized as follows:
- Concentration of political power in Franco. The “unwavering commitment” to the Caudillo was the key element of the whole political edifice of Francoism.
- Defense of the “unity of the homeland.” Refusal of any political autonomy of the regions
