45) As a result of deforestation, the number of different habitats in a particular locale declines
while, at the same time, the rate of cladogenesis in a particular lineage of animals in this locale
increases. Choose the feature that most likely accounts for this observation. A) adaptive radiation
B) allopolyploidy C) autopolyploidy D) increased habitat differentiation E) increased sexual
selection Ans wer: E
Solution
cladogenesis is a phenomenon of evolution in which a species is splitted into two distinct species
called clade. Decrease in habitat will increase the chance of sexual reproduction due to
accumulation of organisms sharing the same habitat and accumulation of variation due to sexual
reproduction will cause speciation.
