Document Summary
General question: how do traits at di erent levels of biological organization evolve in a coherent fashion? organisms are complex and hierarchical entities. you can make gures with dna on bottom, and with behavior at top. Darwinian tness - 3 primary tness traits: age at rst reproduction, how many babies per year (fecundity), lifespan (reproductively). Although scientists tend to specialize on particular levels of biological organization, organisms evolve as coordinated wholes. therefore cross-disciplinary studies are required to understand how organisms work and evolve. Selection: a correlation between tness and one or more traits at lower levels of organization ex- organelles and organs to how many pups u make. Usually you think is going on selection is often acting up to the level of behavior. generally speaking, when we put it in and oherent context we thing behavior is the most direct target of selection.
