Without heredity what use would there be to selection and why evolution? Just take beneficial mutations in the germ line for example. No heredity and nothing to enter the populations gene pool and no evolution. No heredity and there would be no variation in populations and the first environmental challenge would carry your population to extinction.
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
In order for the theory of evolution to hold true within a population, there must be genetic variation among individuals, a mechanism for inheritance of traits from parents to offspring, and differential survival and reproduction based on these inherited traits. These conditions allow for natural selection to occur, driving the process of evolution within a population over time.
All organisms must reproduce.
For evolution by natural selection to occur, there must be genetic variation within a population, some of which must be heritable. The environment must exert selective pressure on the individuals, favoring those with advantageous traits that increase their chances of survival and reproduction. Over time, these advantageous traits will become more common in the population due to differential reproductive success.
For evolution to occur, there must be genetic variation within a population, inheritability of these genetic traits from one generation to the next, differential survival and reproduction based on these traits (natural selection), and long periods of time for changes to accumulate across generations.

There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
The process of evolution is affected by changing environments over time. Species must adapt to changing conditions in order to survive and reproduce successfully. Those that are unable to adapt may face extinction.
