Which process in a hybrid zone increases the likelihood of speciation? A. stability – when a hybrid zone remains the same B. reinforcement – when a hybrid zone widens and fewer hybrids are formed C. convergence – when a hybrid zone narrows and more hybrids are formed D. fusion – when a hybrid zone disappears and separate species fuse into one
The three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.
