Study Notes
- Behavioral ecology studies how ecological pressures lead to the evolution of animal behaviors.
- Instinctual behaviors are inherited and often adapted due to external factors.
Social Behaviors
- Evolved behaviors can benefit individuals directly or through social group formation.
- An evolutionarily stable strategy (ESS) is a set of interacting social behaviors that creates stable social relations.
- Penguins huddling together in winter is an ESS that improves their chances of survival.
Territorial Behavior
- Territorial behavior evolves in response to limited resources in an ecosystem.
- Lions protect their territory to ensure their food supply isn't depleted by other predators.
- Territorial behavior is an evolved instinct, not a conscious calculation.
Mating
- Mating, involving mate selection and offspring production, is crucial for species survival.
- Species find qualities attractive in mates that indicate a higher chance of survival for offspring.
- Male elk fighting demonstrates strength, indicating offspring could fight off predators.
- Bird mating rituals with gift-giving indicate resourcefulness.
- Females typically select mates while males compete, increasing the chance of offspring survival.
Child Raising
- Many species evolve tighter family units for a better chance at survival through shared child-raising responsibilities.
- Humans have evolved to raise children socially, with influences from various individuals beyond parents.
- Tighter family groups, found in many primates, enable shared responsibilities like childcare, food production, and defense, benefiting the entire group.
