Which factor most likely caused animals and plants in India todiffer greatly from species in nearby southeast Asia?(A) The species became separated by convergent evolution.(B) The climates of the two regions are similar.(C) India is in the process of separating from the rest of Asia.(D) India was a separate continent until 45 million years ago.
After the mass extinction that occurred 65 million years ago, mammals rapidly diversified to occupy habitats that were previously unavailable to them. What concept does this illustrate? A. Adaptive radiation B. Cretaceous selection C. Reproductive isolationD. Heterozygote advantage
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.
