Which option lists examplesb.;y mdgey:3a of evi8 :gxedoo+9 m,x c9k-gvr7awidence that can be used to support the theory of kw,a:x xe7mo +-c v8grd9oi9g evolution?
A. Sudden appearance of complex organisms, fossil record, homologous structures
B. Fossil record, homologous structures, size of organisms
C. Homologous structures, speciation, fossil record
D. Speciation, the complexity of organisms, increasing size of organisms
参考答案: C
本题详细解析:
The fossil record provides evidence of evolution, as the sequence in which fossils appear matches the sequence that they would be expected to evolve. Homologous structures provide evidence of evolution as they provide evidence that organisms shared a common ancestor. Speciation provides evidence of evolution as when populations become reproductively isolated, then natural selection can act differently on those populations, resulting in the formation of new species. Choice C is correct. Choices A and D are incorrect as the organisms becoming more complex does not necessarily correlate with evolution. Choice B is incorrect, as the increasing size of organisms does not necessarily correlate with evolution.
