Evidence demonstrates that Escherichia coli and bacteriophage T4 engage in reciprocal evolutionary adaptations, such as phage genome modifications countering bacterial defense systems.
The retrieved literature contains specific studies and reviews discussing the evolutionary interactions, genomic modifications, and defense/counter-defense mechanisms between Escherichia coli and bacteriophage T4. Papers [4] and [10] directly address these coevolutionary processes, providing clear support for the claim.
