ExplanationA. True. For example speciation by polyploidy, the more plant species in alineage, the more species are available to hybridize with one another toform new species.B. True. Animal-pollinated plant families have, on average, have more manyspecies than their closely related families pollinated by wind have.C. False. Animals with complex behavior are likely to form new species at ahigh rate because they make sophisticated discriminations among potentialmating partner. Such discriminations can greatly influence whichindividuals are most successful in producing offspring and may lead torapid reinforcement of reproductive isolation between species.D. True.Reference: Life science of Biology 7th edition.
