ANSWER 6.5
Yes, some individuals with certain traits are more likely to survive and pass those traits to their offsprings.
Reason - This is due to the survival advantage that these individuals have over others. These positive advantageous traits get accumulated in the population over time and ultimately result in individuals who would look different their ancestors. For example, the evolution of horse.
ANSWER 6.6
There must be sudden environmental change.
Reason- This is because the the evolution by natural selection happens when the indiduals have heritable adaptive traits that help them to better suit to the changes in environment as compared to other who cannot adapt to those environmental changes.
