The formation of a mountain range gradually divides one population of lizards into two. Once the mountain range is formed, there is no gene flow between the two populations. One population experiences a dry, hot climate, and the other is exposed to a much wetter environment. Over time, you would expect:
A. sympatric speciation
B. the genotypes of the populations to diverge
C. each population to accumulate adaptations to its current environment
all of the above
B and C only
