Evolution Exam 3 – FAU Study Guide – Comprehensive Revision Notes
Adaptation - ANS ✔✔A trait that helps an organism survive and reproduce
The process whereby the members of a population become better suited to some feature of
their environment through change in a characteristic that affects their survival or reproduction
Recognizing True Adaptions - ANS ✔✔Complexity
Design
Experimentation
Comparative Method
Argument from Design - ANS ✔✔Find a watch, clearly someone design this watch, put thought
into it. The fact that we see complex functions indicate a creator (GOD).
All traits adaptations - ANS ✔✔A trait may be a consequence of physics or chemistry
Traits - ANS ✔✔Evolve by Genetic Drift
Evolve by Genetic Hitchhiking
Consequence of Phylogentic History
Not all necessary adaptions
Complexity - ANS ✔✔The eye, highly vascularized structured. Highly complex. (pecten)
oxygenate the retina in a bird's eye.
Experimentation - ANS ✔✔Manipulate to see what happens when I play with this feature, is it
beneficial or detrimental?
, Comparative Method - ANS ✔✔Seeing same features popping again and again, in unrelated
lineages, then it's necessary for certain things. It's not a coincidence.
Preadaptation - ANS ✔✔Possession of the necessary properties to permit a shift to a new niche,
habitat, or function.
Preadaptation - ANS ✔✔An organism's use of an anatomical feature in a way unrelated to the
feature's original function
Exaptation - ANS ✔✔Shaping of a useful feature of an organism by natural selection to perform
one function and the later reshaping of it by different selection pressures to perform a new
function
Not to Expect from Adaptation - ANS ✔✔Necessity
Perfection
Progress
Harmony & Balance of Nature
Morality & Ethics
Necessity - ANS ✔✔Just because the environment changes, doesn't mean the organism has to
adapt. Controversy, adaptations happen because of dramatic changes.
Harmony & Balance of Nature - ANS ✔✔Prevalent in a lot of documentaries, bees looking
buzzing from flower to flower, making sure they pollinate every flower, no, the bees are looking
for themselves, not for the flower.
Sexual Selection - ANS ✔✔Differential success due to variation among individuals in their
success at getting mates.
