According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? 

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals are better adapted to exist in their environment than others are. 
• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes. 
• Some individuals tend to produce fewer offspring than others in the same environment.
