Lion
Lions demonstrate remarkable but ultimately limited adaptability. Panthera leo has evolved to thrive in savannah and grassland environments, with some populations adapting to semi-desert conditions in Namibia and forest edges in Central Africa. However, lions cannot survive in urban environments, arctic conditions, or marine ecosystems. The Feline Adaptability Index, developed by Cambridge's Department of Evolutionary Biology, rates lions at 34 out of 100, noting their 'specialised apex predator design limits environmental flexibility.' Lions require approximately 7 kilograms of meat daily and struggle with habitat fragmentation, showing little ability to modify their fundamental behavioural patterns.
Tacos
The taco exhibits what food scientists call 'infinite morphological plasticity.' The basic taco template, a tortilla embracing fillings, can accommodate virtually any ingredient combination known to gastronomy. The International Taco Adaptation Registry documents over 15,000 distinct taco variants, from traditional carnitas to Korean BBQ tacos to the controversial breakfast taco. Tacos have successfully adapted to vegan, gluten-free, and keto dietary frameworks. They function equally well as street food or haute cuisine, at breakfast, lunch, dinner, or 3 AM. The taco thrives in all climate zones, economic conditions, and cultural contexts. Its adaptability rating on the Culinary Evolution Scale: 97 out of 100.
