The plants and animals of the Galápagos Islands have evolved distinct phylogenetic traits that are found nowhere else on Earth. Each island is home to species with unique characteristics not seen on any of the neighboring islands, reinforcing their biological isolation. These island-specific organisms are known as endemic species. As Charles Darwin noted in On the Origin of Species (1859), an endemic species is shaped by the particular conditions of the place it inhabits and cannot be found elsewhere. A parallel can be drawn in the field of architecture. Similarly, the study of typologies is a way to classify buildings that share similar features in their form. Analogous to evolution in flora and fauna, the development of building typologies is also influenced by the context in which they evolve. In this sense, typologies that originate in a specific location and are not found elsewhere may be considered architecturally endemic. This chapter presents a morphological analysis of the urbanized waterfront in Puerto Baquerizo Moreno, located on San Cristóbal Island, with a special focus on restaurant building types. Restaurants in San Cristobal exhibit typological characteristics unseen on mainland Ecuador that have emerged through adaptations driven by landscape, usage, and culture. These unique characteristics of the locale have resulted in newly emergent typologies of the Galapagos that have evolved in dialogue with the environment. The methodology employed juxtaposes and compares the urban and architectural scales of the built waterfront across specific historical periods. This chapter focuses on the typology of the restaurant, which has historically served fishermen, naval personnel, and tourists at different points in time. It examines how the morphology of this building typology reflects social and demographic shifts on the island of San Cristobal, in this way shaping the built environment. The research analyzes building typological transformations as adaptive responses to environmental, social, and geographical conditions, using San Cristóbal’s waterfront as a case study.
