1) Leopardiem tāpat kā citām zīdītāju sugām var parādīties melānisms. Mutāciju rezultātā ādā un apmatojumā lielā daudzumā uzkrājas tumšais pigments – melanīns. Melnie leopardi kas pazīstami kā ,,melnās panteras,, visbiežāk sastopami mitros,biezos mežos. Tuksnešos dzīvojošie ir blāvi dzelteni, bet zālienos dzīvojošie – tumšāk dzelteni. Kādi evolūcijas faktori ir ietekmējuši šādu leopardu dažādību? Kā varētu prognozēt turpmāko šīs sugas attīstību?
2) Salīdziniet 2 vienas ģints dzīvnieku sugas! Kādas ir viņu kopīgās un atšķirīgās pazīmes?
