; Sexual Selection Landmarks
: '''The 'Sexy Son' Hypothesis''' → The "Idea" that females "Choose" "Attractive Males" "So That" their "Sons" will "Also be Attractive" and "Reproduce More."
: '''Infanticide in Lions''' → A "Dark Side" of "Competition": a "New King" "Kills" the "Cubs" of the "Old King" to "Bring the Females back into Heat" (Maximizing 'His' genetic success).
: '''Extra-Pair Copulation''' (EPC) → The "Discovery" that "Socially Monogamous" birds (90% of species) are "Genetically Promiscuous" (~10-20% of 'Chicks' are not the 'Father's').
: '''Pheromones and the 'MHC' ''' → (See Article 599). The "Theory" that humans "Choose Mates" based on "Smell" to "Find" someone with a **"Different Immune System"** (Improving 'Child Health').
