Episode notes
INSIGHT

Sex Evolved for Genetic Variation

  • Sex evolved to increase genetic variation beyond mutation alone.
  • This variation provides adaptive advantages to changing environments over time.
INSIGHT

Anisogamy Defined and Prevalent

  • Anisogamy means reproduction via two different-sized gametes.
  • Most animals use anisogamy, with distinct small sperm and large eggs.

Male, Female, and 3G Clusters

  • Male and female are heuristics based on gamete size but vary by species.
  • In humans, 3G sex clusters genetics, gonads, and genitals but have exceptions.
