Studies reveal remarkable biological adaptations and behaviors: ants exhibit anticipatory path clearing via swarm intelligence; freshwater snails demonstrate molecularly distinct predator-induced plasticity across generations; and ladybirds’ distinct coloration arises from pigment and physical wingcase structures. Furthermore, laboratory mice with natural gut microbiota show wildling-like phenotypes, and bioengineered lymph node-on-a-chip models promise to enhance immune response research. These insights deepen understanding of natural and engineered biological processes with potential applications across ecology, evolutionary biology, and medical research.
