Aristotle's Rational Choice Theory

Rational Choice Theory

• Human beings make decisions based on rational choices, according to Aristotle
• Individuals select actions or scientific investigations that align with their personal preferences
• Rational choice theory models this decision-making process
• The theory is used to analyze how people make choices based on their individual preferences

Changes in Human Body

• Earliest human species (6 million years ago): small, long arms, short legs, and long guts to digest plant-based food.
• Adaptation to hot climates (9 million years ago): narrow bodies, long legs, and short guts to allow for efficient heat dissipation and quick digestion of meat.
• Adaptation to cold climates (400,000 years ago): short, wide bodies to conserve heat, dependent on raw and cooked meat, with compact bodies and short guts.

Evolution of Bones

• From 50,000 years ago: bones became sleeker and weaker due to less physically demanding lifestyles and a diet that included meat and cooked foods.

Complexity of the Brain

• Environmental changes drove the evolution of larger and more complex brains, enabling early humans to process and store more information, facilitating social interactions and adapting to new habitats.
• Brain size tripled, becoming the largest and most complex of any living primate.
• Ability to process environmental information drives evolution, enhancing survival chances.
• Human brain evolution focused on selective pressures from physical (climate, diet, food availability) and social (group size, parental care) environments.
