exam 1 definitions to know Flashcards
do individual learning and cultural transmissions make it across generations or between?
The information acquired via individual learning doesn’t make it across generations only within. cultural transmissions can affect both within- and between-generation effects.
inclusive fitness
the sum of its direct and indirect fitness
are the mind and body separate entities?
no they are connected
adaptive radiation
a process in which a single species rapidly diversifies into many new species that fill different ecological niches
parent-offspring regression
Parents pass on genes to their offspring, so when narrow-sense heritability is high, the behavioral variation in the offspring should map onto the behavioral variation observed in parents.
eusociality
An extreme form of sociality that is present in many social insect groups (ex: naked mole rats).
homology
a trait shared by two or more species because they share a common ancestor (ex: female mammals produce milk for their young because mammals share a common ancestor that produced milk) used in phylogeny trees
homoplasy
a trait shared between two or more species not because they share a common ancestor but natural selection has acted independently on each species (ex: wings on birds and wings on insects) not used in phylogeny trees
which is more representative of the way life has evolved phylogenetic ladders or phylogentic trees?
phylogenetic trees are. the phylogenetic ladder has simple life forms at the bottom and complex at the top
generalists
better able to adapt to changing environments (we are generalists)
specialists
better adapted in stable environments
genetic continuity
the process by which genetic information is passed from one generation to the next
contiguity
two events that occur close together in time will associate the representation of the two. 2 events will become associated regardless of what comes first
habituation
the diminishing of a physiological or emotional response to a frequently repeated stimulus
sensitization
a psychological phenomenon where repeated exposure to a stimulus leads to an increased response to that stimulus or similar stimuli.
foraging
the act of searching for and gathering wild food resources
polygenic
Polygenic traits are influenced by multiple genes
direct fitness
of offspring
reproductive fitness
of grand offspring
