Hedgehog
Hedgehogs demonstrate remarkable environmental flexibility. Seventeen species have successfully colonised habitats ranging from European woodlands to African savannas to Asian deserts. The European hedgehog has adapted to suburban environments with impressive efficiency, treating gardens as bountiful hunting grounds and shed bases as premium real estate. Their omnivorous diet—encompassing insects, slugs, frogs, eggs, and the occasional snake—allows exploitation of virtually any ecosystem offering invertebrate prey. Hedgehogs have even adapted their ancient hibernation cycles to accommodate climate change, demonstrating metabolic flexibility that many larger mammals lack.
Panda
The giant panda represents adaptation's opposite trajectory: extreme specialisation. Having evolved as a carnivore, the panda inexplicably abandoned this efficient digestive heritage to consume bamboo exclusively—a food source providing such minimal nutrition that pandas must eat 12 to 38 kilograms daily merely to survive. Their digestive system retains carnivore characteristics, processing bamboo at a mere 17 percent efficiency. This dietary commitment restricts pandas to specific mountain ranges in central China where bamboo flourishes. When bamboo forests flower and die—an event occurring synchronously across entire species—pandas face starvation unless alternative bamboo species exist nearby. The panda has, through evolutionary stubbornness, painted itself into an ecological corner.
