Darwin proposed that three conditions of life underlie the reason that species change through time adaptively. They are as follows:
A) Populations grow beyond what the environment can handle; organisms vary; and some of the variation is genetic.
B) Populations are adapted to avoid growing beyond what the environment can handle; organisms vary; and some of the variation is genetic.
C) Populations maintain equilibrium; species are immutable; and most of the individuals in a species are the same.
D) Populations grow beyond what the environment can handle; organisms vary; and variation that is acquired in life can be passed on genetically.

Darwin's theory of natural selection is based on the idea that populations can grow beyond what the environment can support, leading to competition for resources. Organisms within these populations vary, and some of this variation is heritable. These conditions create the basis for natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to the next generation.
