chapter 43 Flashcards
What is a behavior?
Any action by an organism, genrally a response to an stimulus, (a pieace of information gathered about the enviroment.
What is behavior a part of?
phenotype
Proximate
short term process acting within an individual’s lifetime affecting the behavior.
Ultimate
Long term evolutionary processes affecting the behavior.
Origin of a behavior
Developmental and Evolutionary
Developmental Behavior
How is the behavior acquired over an individuals lifetime?
Evolutionary Behavior
Where and how did the behavior arise in the past?
Implementation of a Behavior
Mechanistic and Adaptive
Mechanistic
How is the behavior caused through neural, muscular, and other processes?
Adaptive
How does the behavior enhance the survival and/or reproduction of individuals?
What are the 4 Niko Tinbergen’s question about any behaviors
Causation, development? , adaptive function’s? , evolutionary history?
Causation?
What causes the behavior to be performed example Responding to day length shift, air is passed through the syrinx, another male is singing nearby.
Development
Varies across bird species listen to father sing, hearing other, innate
Adaptive functions
Territory, mate, offspring , etc
Evolutionary history
Species specific songs are selected for through natural selection.
Did dinosaurs sang
yes!!!
How is the animal behavior shaped?
Animal behavior is shaped in part by genes acting through the nervous and endocrine systems.
What is learning a behavior of?
Learning is a change of behavior as a result of experience
Where does behavior comes from?
Behavior is influenced by both genetic (innate) and environmental(learned) factors
What did behavior evolved by?
Behavior evolves by natural selection just like another traits
What does behavioral traits vary on?
Populations
What basis does behavioral traits have in populations?
genetic basis
What do individuals with more advantageous behavior reproduce?
more offspring
What do advantageous behaviors do?
Increase
A common way to interpret a behavior?
Why does it increase survival and reproductive success? (ultimate causation!!!)
Courtship displays?
species- specific, highly repeatable similar among individuals of the species- WHy??
what is a fixed action pattern in Geese
Normal egg retrieval by a goose is an example of fixed action pattern, a stereotyped behavior in response to a stimulus
When does the behavior still persists?
Even if the egg is tied with a sting preventing it from being brought to the nest and a soccer ball elicits an even stronger response.
