Scientific Evidence of Evolution
Classic Evidence
- Morphological: The study of comparative anatomy allows us to understand the similarities and differences that the same organ presents in different species.
- Paleontology: Paleontology studies fossils, which allow us to know the ways that life forms existed in the past and study their evolutionary relationship with current life forms.
- Embryological: Embryology studies the early development of organisms. The principle of recapitulation states that the embryonic
Economic Cycles: Inflation, Housing, and Oil Impact
Cyclical Inflation
When there’s high unemployment, stocks piling up in warehouses, and low production levels, the European Central Bank (ECB) might inject cash into the economy. The president of the ECB achieves this by buying government bonds from the capital market. This sale provides banks with high cash reserves. However, cash earns low interest compared to other assets, so banks prefer to lend it out.
Banks then offer businesses attractive loan deals, encouraging expansion. After expanding, the

Population, Gender, and Age Distribution, Mobility
Background: Populations can change through three processes: fertility, mortality, and migration.
Gender Distribution
- Masculinity Index (sex ratio): Number of males per 100 females = M/100 F
- Femininity Index (sex ratio): Number of females per 100 males = F/100 M
- In the Czech Republic:
- MI is highest in newborns = 105M/100F
- MI 35-40 years = 100M/100F
- MI 80 years = 50M/100F
Age Distribution
Biological Criteria – 3 Generations
- Children (pre-reproductive): 0-14
Spanish Economy: State Intervention & Infrastructure (1898-1929)
State Intervention
Another feature of the Spanish economy was the restriction of competition between companies and consistent state intervention in the economy. Companies established agreements to fix prices. This led to higher sale prices in Spain compared to other countries. The steel industry, particularly the company Altos Hornos de Vizcaya, clearly exemplified this restriction of competition, practically monopolizing Spanish iron and steel production.
State intervention manifested in two directions:
