Conditions 1 and 2 must always be true for populations to evolve due to natural selection. Variation in traits that are heritable is necessary for natural selection to act upon, and heritable traits that increase reproductive success will be selected for and increase in frequency in the population over time. However, individuals do not pass on all traits they acquire during their lifetime, as this is not how inheritance works.
