Darwin wrote that individuals with superior physical or behav. traits are most likely to survive to produce offspring so their attributes (genetic traits) would be passed to future generation. This is known as “survival of the fittest Favorable (adaptive) traits will increase in population so population will gradually change. Remember- populations evolve, individuals do not evolve. Evidence for genetic change with time. Present day examples of the development of insects resistance to insecticide, bacteria resistant to antibiotics, Understand what homology is, and know examples.
