success in environment have advantage
- Introduced by Darwin
- Nature/evolution selects characteristics/genetic mutations over time that increases
your chance of evolutionary survival and reproductive success
Genetic Transmission: Replication and mutations

“Genes ‘try’ to spread themselves by wiring animals’ brains so that animals love their kin
and try to keep them warm, fed, and safe” (Pinkser, 1997)
