Which of the following assumptions or observations is not part of darwin's idea of natural selection?
a) organisms compete for limited resources.
b) whether an organism survives and reproduces is almost entirely a matter of random chance.
c) heritable traits that promote successful reproduction should gradually become more common in a population.
d) populations produce more offspring than their environment can support.

The branch of science which deals with the gradual change of an organism is called evolution.

The correct answer is B.

Charles Darwin is considered the father of evolution. He wrote the book Origin of species.

He gave the theory of natural selection in which he gave postulates about the adaptation of the species and the survival of the species in nature.

The Incorrect option is B because reproduction is not a random process. reproduction is a process to pass the genes to the next generation and for that species must survive.

Hence, the incorrect option is B that is Whether an organism survives and reproduces is almost entirely a matter of random chance.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
