english: It's particularly astonishing because each one of these organisms, each subsystem, each cell type, each gene, has evolved in its own unique environmental niche with its own unique history.
non_english: Posebno je zadivljujuće jer je svaki od ovih organizama, svaki podsistem, svaki tip ćelije, svaki gen, evoluirao u svojoj jedinstvenoj prirodnoj sredini, sa svojom jedinstvenom istorijom.
