If a phylum's body plan fails to enable its members to survive and reproduce, it may face extinction over time. Natural selection will favor organisms with more advantageous traits, leading to a decline in the population of the less suited phylum. This process can result in the phylum becoming obsolete or, in some cases, evolving new adaptations to survive in changing environments. Ultimately, if the body plan remains ineffective, the phylum may vanish entirely from the evolutionary landscape.
