Answer is (C). : Biological evolution is the process of biological change over time based on the relationships between species and their environments. As the environment changes, it creates a selective pressure such that only some individuals in the population will survive. Th ose that survive are able to pass on the genes that gave them the advantage, assuming the advantage was a heritable genetic trait. If so, the off spring will inherit the trait and will also be better able to survive the environmental conditions, passing the trait along to their off spring. Over time, this results in populations that are adapted to their environmen.
