What are Tindenberg’s 4 Questions?
1-Causation/Mechanism
2-Development/Ontogeny
3-Function/Adaptation
4-Evolution/Phologeny
Causation/Mechanism explains?
What type of stimulus would cause organism to react/ What type of stimuli would elicit a response
Development/Ontogeny explains?
How the behavior changes with age/ What earlier experiences need to occur for behavior to be shown?
Function/Adaptation explains?
How does the behavior impact the animal’s chance of survival and reproduction (AKA fitness)
Evolution/Phylogeny explains?
How the behavior compares to similar behavior in related species
What is fecundity?
of offspring produced in each reproductive episodfe
What is parity?
how many times a organism reproduces in a lifetime
What is the behavior being displayed in the prairie vole example?
Monogamy
What is the mechanism in which the prairie voles demostrate?
The mechanism is the avpr1a gene, which produces proteins on the ventral palliadum section of the brain, which after intercourse the hormone vasopressin binds to the protein and a neurological signal is transmitted to the body of the prairie vole causing them to feel happiness and contentment.
This feeling cues the prairie vole to stay with the female
How does the prairie vole and the Montree vole differ?
Both voles produce the avpr1a gene, however the Montree vole has a modified promoter region which doesn’t allow as many receptors to form. A genetic mutation which affects the transcription of mRNA.
How did scientists test to see if the avpr1a gene was the one causing the prairie vole’s monogamy?
Larry Young (the discoverer of the avpr1a gene) virally infected polygynous voles ventral pallidum and inserted avpr1a
The results of this was that these voles exhibited more monogamous behavior after experiment
What is the development that must occur for the prairie voles to exhibit the behavior?
There has to be proper development of ventral pallidum/brain in young vole and gene must be present; receptors must be present.
Must reach sexual maturity and must have reproductive event/opportunity to experience circulation of vp horomone through body and brain.
What is the evolutionary aspect to why the Prairie voles exhibit this behavior?
Guaranteed reproductive certainty/paternal certainty
Increased fitness
What is the adaptive aspect of why the Prairie voles exhibit this behavior?
It gives the male prairie voles more parental care
kin recognition comes into play
PROMT:
Describe Eusocialty
Eusociality the highest level of organization of animal sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes called castes. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste.
PROMT:
Altruism
the principle or practice of unselfish concern for or devotion to the welfare of others
PROMT:
Hapliodiploidy
Haplodiploidy is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid
