Why do organisms evolve?

Organisms make changes to help them survive and reproduce in their environment.
Changes in the environment cause organisms to change.
Organisms with traits that help them survive and reproduce in their environment pass on those traits
. Organisms naturally select traits that help them survive and reproduce.

Evolution is driven by natural selection—organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. Over time, these beneficial traits accumulate within a population, leading to evolutionary changes. Additionally, random genetic mutations can also contribute to the evolutionary process by introducing new variations that may be advantageous in certain environments. Ultimately, the primary driving force behind evolution is the need for organisms to adapt to changing conditions in order to ensure their survival and reproductive success.
