Lecture 1 E Flashcards
Name three founders of Ethology
Karl Von Frisch
Konrad Lorenz
Nickolas Tinbergen
What is Karl Von Frisch known for?
The waggle dance in honeybees
Workers recruit other workers at hive to exploit food resources
What is Konrad Lorenz famous for?
Imprinting in geese
The process by which some nidifugous birds bond instinctively with the first moving object that they can see within the first few hours of hatching
What are the four major categories for explanations of animal behaviour
Causation
Development
Function
Evolution
What are the questions associated with CDEF?
Causation: how is the behaviour achieved?
Development: how did it develop?
Evolution: how has it evolved?
Function: what is the behaviour for?
Where has the tail wagging behaviour in dogs come from? How has it evolved in ancestral species?
From tail raising and tail vibrating behaviour in ancestral wolves
What is innate behaviour?
Not changed by the learning behaviour
What is spontaneous behaviour?
Those that occur in their completed form the first time they were preformed and that seemed resistant to the effects of learning
What is behaviour?
The total movements made by the intact animal
What are the proximate explanations of behaviour?
Causation
Development
What are the ultimate explanations of behaviour?
Function (what is the behaviour for)
Evolution (where has it come from)
What is ontogeny?
Describes how behaviour develops over an animals lifetime
What is phylogeny?
Describes how a behaviour has evolved
What is adaptive value?
Describes how behaviour contributes to an animals lifetime reproductive fitness
Why do dogs wag their tails when they see companions?
C- hormonal response to stimuli, signal transmission in NS
D- Around 3-4 weeks; genes x experience
F- To communicate
E- From an ancestral behaviour (tail-raising in wolves)
