Physiology - ✔✔The branch of biology that deals with the functions of living
organisms and their parts
natural selection - ✔✔Organismal function has been shaped by _________
in different environments.
Darwin's 4 postulates of natural selection - ✔✔1. Phenotypes vary within
populations
2. Some of this variation is passed on to offspring
3. In every generation, more offspring are produced than can survive
4. Some individuals survive and reproduce more effectively that others, and
this success is associated with their phenotypes
predict - ✔✔Evolutionary reasoning allows us to ________ physiology
based on knowledge about local environments, not just
catalogue it across organisms and environments.
Intergrative - ✔✔Physiology affects and/or responds to all levels of
biological organization; Physiology is an inherently ________ discipline.
,Mechanisms and Origins - ✔✔What are the 2 broad types of questions in
animal physiology about?
What is the mechanism by which a function is accomplished? - ✔✔State
the question on mechanisms.
proximate causation - ✔✔What is the question about mechanisms about?
How did that mechanism come to be? - ✔✔State the question on origins.
ultimate causation - ✔✔What is the question about origins about?
Mechanism - ✔✔Interactions between the components of living animals
that enable these animals to perform and function as they do.
Mechanism - ✔✔The field of physiology is most clearly differentiated from
other fields (e.g. ecology, animal behavior) by this focus on _______.
Evolution - ✔✔Questions about the origin of a physiological function are
fundamentally about the ________ of that function and its broader
ecological and adaptive significance
Inference - ✔✔Answers to questions about origin are usually understood
with less certainty than questions about mechanism, because they often
rely on indirect forms of _______.
Adaptations - ✔✔Physiological mechanisms are almost always
_________—traits that have arisen as a result of natural selection.
, Animal Physiology - ✔✔________ is an inherently integrative field of study
that asks questions about the origin of, and mechanisms underlying, animal
function.
Evolutionary - ✔✔The field of animal physiology is based heavily in
_______ biology, and specifically, the ways in which physiological features
have arisen via natural selection.
Predict - ✔✔Evolutionary theory allows us to ______ what physiological
functions a given species might have, and it gives us a basis for making
hypotheses.
Continuous; dynamic - ✔✔The atoms of animal bodies undergo ________
and _______ exchange with the atoms of their environments
organization - ✔✔In animals, it is the general ________ of these atoms that
persists through time, rather than the individual atoms themselves
Energy - ✔✔To maintain organization of atoms, animals require the input of
______.
Homeostasis - ✔✔Because animals dynamically interact with their
environment, they must maintain _______.
Homeostasis - ✔✔The maintenance of a stable (or nearly stable) internal
environment
