- Natural selection (will/will not) produce absolute perfection, not do we always need, as far as we can judge, with this high standard in nature - Darwin
- --- may increase the fitness of parents as well as the siblicidal offspring if the offspring that is killed is likely to die anyways
- T/F Behavior that results in indirect fitness gains is favored by KIN SELECTION
- T/F Sexual reproduction imposes different selection pressures on females vs. males
- T/F older birds/chicks that are more closely related to their parents are more likely to be recruited to take care of new chicks
- T/F Organisms face fundamental trade-offs in their use of energy and time
- is "selection for" essentially an adaptation?
- In regards to Number & Size of offspring, selection on parents favors a compromise between the quality and quantity of offspring BUT....
- T/F Natural Selection CAN always explain sexual dimorphism
- differential reproductive success due to variation among individuals in success at getting mates
