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.
Which of the following are true about outgroups?
