The four postulates of natural selection are-All individuals in a population have equal reproductive success,Individuals in a population vary in the traits they possess,Survival and reproduction success are variable among individuals in a population,Some trait differences are heritable.
Explanation:
Natural selection is a process by which those organisms that adopt the environmental condition have the chance to increase in number and those organisms that are unable to adopt the environmental condition will be less favorable.
Natural selection have 4 conditions that are Reproduction,Heredity,Variation in fitness of organisms and variation in traits of the individuals.
Reproduction-is a condition which is important for evolution as the parent produce offspring that will survive.
Heredity-is a kind of mechanism when the transmission of genetic information takes place from parent to offspring.
Variation is important as it considers the fitness of organisms as they have different heritable factors.
