Human and animal communication: Von Frisch's bee study
The study
This study changed the way scientists thought about animal communication.
Method
Von Frisch put a food source close to the hive (within about The specificatio Difference human and anima von Frisch Know the tas Bus old de Lenneberg different one recall future Berinmo apir Whorf Hopi time English memory 10-20 metres), as well as one further away (up to 300 metres). van Over 20 years he made more than 6000 observations
Aim
To describe the dance of the honey bee as a means of communicating information to each other
Conclusion
Bees use a sophisticated form of animal communication The signalling system has evolutionary value as it helps their survival.
Results
Worker bees tell the others where pollen is located by two
types of dance:
Round dance: Bee moves in a circle to indicate food is less than 100 metres away.
Waggle dance Moving in a figure of eight, bee waggles its abdomen on the straight line in the middle of the eight. This line points at the source of pollen Speed indicates distance
60% of bees went to food sources at the distance indicated by the dances
Evaluation
Scientific Value
A strength is that Von Frisch's work made an important contribution to science. People knew that bees danced but had no understanding of the meaning of the movements.
Sound matters too
A weakness is that the importance of sound was overlooked Another researcher found that when bees performed dances in silence, other bees would not then go on and investigate food Source.
