Like last week, I’ll explain some concepts:
Let’s recap some of last weeks’s concepts:
Sexual selection theory1 Darwin (1871) / Parental investment theory2 Trivers (1972)
Fisherian Runaway3 Fisher (1930) / Handicap principle4 Grafen (1990);Zahavi (1975);Zahavi & Zahavi (1999)
Sexual Strategies Theory5 Buss & Schmitt (1993)
Other concepts:
‘Good Genes’
‘Dad’ vs. ‘Cad’
