Adaptionism Flashcards
how can we see the design in living systems?
ecology, development and biochem
what did Paley tell us?
rock vs watch analogy
rock natural you dont think it has a designer
what is it thats different about a watch to make you think someones desinged it - apparent design needs a designer
then compares it to the eye - complex - lots of types eg fish vs human differences in light diffraction
what does naturalistic trial and error show us?
survival of the fitest - increases reproductive success - provides an explanation for which organisms were designed for
what does adaptationism show us?
we can concede traits are shaped by more than ns but ns still supplies the only naturalistic explanation
a useful research tool
whats the critique to adaptationism?
just so stories - come up with an explanation but with little more than plausability
what is the optimal approach?
fitness by phenotype, the actual not quite what was predicted so a new model that the actual phenotype fits better
whats the comparative approach?
two different phenotypes best fit to the individual niche eg hot and cold
