chapter 53 :
53.1 :
ethology: An approach to the study of animal behavior developed in Europe.
Emphasizes the causes of the evolution of behavior.
53.2:
deprivation experiment : investigators rear a young animal so that it is deprived of
all experience relevant to the behavior under study. If it still exhibits the behavior,
we may assume that the behavior can develop without opportunities to learn it.
genetic experiments : investigators alter the genomes of organisms by interbreeding
closely related species, by comparing individuals that differ in only one or a few
genes, or by knocking out or inserting specific genes to determine how these
manipulations affect their behavior.
example of deprivation experiment : Squirrel grew up in cage not allowed to learn
from other squirrels, was given a nut and bam it naturally tried to bury it and shit
Selective breeding : Used on this like dogs and plants, so like hybrids
Interbreeding : same breed of ducks like mating calls of same breed of ducks, hybrid
ducks suck at the mating call
Gene knockout experiments : Elminating a gene and seeing what happens, ex. In
mouse they took off the mother caring motivation gene and the mom's didn't give a
fuck about their kids
releaser: A sensory stimulus that triggers the performance of a stereotyped behavior
pattern. (ex. the nut in the squirel experiment)
Wasps get lost if the evironmental cues are displaced
genes help learning, sparrows learning species specific song
Hormones affect certain areas of the brain
53.3:
habitat: The environment in which an organism lives.
Chemicals help chose a habitat

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
