Study Notes

Homo sapiens appeared around 200,000 years ago, with big brains, and groups slowly got bigger.
Humans spend about 20% of their time grooming or preening, which releases oxytocin, the "love" or bonding hormone.
This bonding is not genetic, but arises through touch and communication.

The Emergence of Language

Around 130,000 years ago, some Homo sapiens began to talk, using simple, descriptive language.
The need for more efficient "preening" or "grooming" led to the development of communication.
Language became a primary inherited need, as even well-nourished human babies die without social interaction.

The Brain's Adaptation to Sociality

Around 50,000 years ago, the brain changed its wiring to better process complicated social information.
Cultural aspects of human society, such as music, abstract thought, and symbolic cave art, emerged.

The Shrinking Brain

Around 20,000 years ago, the brain began to shrink from 1500 cubic centimeters to below 1400cc.
Reasons for this include specialization and networked thought, as people didn't have to be as smart to survive in complex societies.
Multitasking is making us stupid, as it increases the production of stress hormones and causes mental fog.

We inherited biological traits, such as empathy, altruism, sense of equality, and sense of morality and fairness.
Mirror neurons help us achieve altruism by feeling sensations that others feel.
Emotions are a key aspect of human decision-making, with neural conduits for transmitting emotional information being faster than rational thought.
