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 naturally select traits that help them survive and reproduce.
Organisms with traits that help them survive and reproduce in their environment pass on those traits.
Over time, this process of natural selection leads to the evolution of new traits and characteristics in a population. The main driving force behind evolution is the need for organisms to adapt to their changing environment in order to increase their chances of survival and reproduction.
When the environment changes, certain traits or characteristics may become less advantageous while others may be beneficial. Organisms that possess these advantageous traits are more likely to survive and reproduce, passing on the genes responsible for those traits to future generations.
Moreover, random genetic mutations can lead to new traits or variations within a population. If these mutations provide a survival or reproductive advantage, they are more likely to be passed on to future generations through natural selection.
Overall, organisms evolve in response to changes in their environment to increase their chances of survival and reproduction, ensuring the continuation of their species.
