the scientific method1
The Scientific Method
  • Observation and causal question: Beewolves find the entrance to their own nests. How do they do it?
  • Hypothesis: They use local landmarks as cues
  • Predictions: If they use local landmarks then manipulating those landmarks should mislead them
  • Test of predictions: Experiments
  • Conclusion: Yes, local landmarks are used by beewolves as cues in finding own nest

The Scientific Method
  • Observationand causal question - black headed gulls remove eggshells. Why did black headed gulls evolve behaviour of eggshell removal?
  • Hypothesis - maybe this behaviour helps parent gulls to conceal their offspring from predators
  • Predictions - if so, broken eggshells should help predators find food
  • Test of predictions - experiment
  • Conclusion - yes, eggshell removal

appears to help parent gulls conceal

offspring from predators
