adaptations
endeavors to demonstrate that various traits of organisms are needed adaptations are called the
adaptationist program
3 steps to the adaptationist program
1 observe or define a trait
2 determine use or usefulness of trait
3 demonstrate that individuals possessing trait have higher fitness
traditional explanation of oxpeckers and mammals was thought to be a co adaptation calle d
mutualism
a symbiotic relationship or interaction between 2 individuals (or different species) in which both partners benefit
mutualism

licking a licking blood from wounds
picking through ears
running bills through ox hair
the birds were not actually helpers to the mammals, but
pests
the traditional explanation of oxpeckers and large mammals living together in blissful mutuals is
incorrect
a caveat for adaption studies based on the oxpecker/mammal system
differences among populations or species are not always
adaptive
a caveat for adaption studies based on the oxpecker/mammal system
not every adaptation is driven by the same selective
pressure
a caveat for adaption studies based on the oxpecker/mammal system
adaptations are rarely, if ever
