Behave

Genes are not autonomous agents commanding biological events. Genetic influence is complex. While genes play a role in behavior, their effects are often small and highly dependent on environmental factors. Gene-environment interactions mean that the same gene can have different effects in different contexts. For example: Cultural factors are crucial. Culture shapes how genes are expressed and how environmental factors impact behavior. Some key cultural influences include: Crucially, the final brain region to fully mature (in terms of synapse number, myelination, and metabolism) is the frontal

This insight from Behave challenges conventional wisdom about success. Robert M. Sapolsky demonstrates through research and case studies that how we think and feel about the subject matters more than technical knowledge or raw intelligence.

Lesson 2: The brain's structure and function evolve throughout life, influencing behavior

This insight from Behave challenges conventional wisdom about success. Robert M. Sapolsky demonstrates through research and case studies that how we think and feel about the subject matters more than technical knowledge or raw intelligence.

Lesson 3: Hormones play a nuanced role in shaping social behavior and aggression

This insight from Behave challenges conventional wisdom about success. Robert M. Sapolsky demonstrates through research and case studies that how we think and feel about the subject matters more than technical knowledge or raw intelligence.
