[单选题]
What sequence of events usualb2wbhc*b8s+ 8 96:zm*k l6o6ih)q pqxf tgiry ly occur during the process2hsada+cnf9)le 8o4t of speciation?
A. Reproductive isolation → one species becomes two species → random mutations
B. Random mutations → reproductive isolation → one species becomes another species
C. Geographic isolation → reproductive isolation → one species becomes another species
D. Geographic isolation → reproductive isolation → one species becomes two species
参考答案: D
本题详细解析:
Choice D is correct because geographic isolation leads to a buildup of different mutations between two populations, leading to reproductive isolation and the production of two species from one. Choice A is incorrect, as reproductive isolation cannot occur prior to a buildup of random mutations. Choices B and C are incorrect because speciation involves one species becoming two, not one.
