- Which of the following statements is false? a. Gradual speciation is most likely to occur in a large population that lives in a stable climate. b. Punctuated equilibrium is unlikely to occur in a large population that lives in a stable climate. c. Gradual speciation and punctuated equilibrium both result in the divergence of species. d. Gradual speciation is most likely to occur in a small population that experiences a rapid change in its environment.arrow_forwardA species is a group of_________ that evolves___________. The biological species concept identifiesspecies on the basis of their_________ . The biologicalspecies concept cannot be applied to species that reproduce_______________.arrow_forwardWhich of the following scenarios best explains how resource partitioning can lead to adaptive radiation? The lack of competition between individuals leads to better survival and reproduction rates. The utilization of different resources requires different adaptations, selecting for different traits. The lack of competition leads to a more balanced ecosystem, resulting in more offspring. There is no connection between adaptive radiation and the resource partitioning in nature.arrow_forward
- What is Allopatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate themarrow_forwardIf the phylogenetic species concept (PSC) were used to define species, rather than the biological species concept (BSC), how might that change the estimates of species diversity (numbers of species) on a worldwide basis? True or False: Estimates of species diversity are likely to change if the PSC is used. In particular, one would expect the number of species to increase. This is because individuals from divergent allopatric populations that can potentially interbreed would belong to the same species under the BSC. These same organisms would be classified as members of different species under the PSC.arrow_forwardPlace a species distribution in order from smallest to largest.

- Which of the following is a conclusion drawn by the authors from the results of this study? Temperate marine invertebrate species are outcompeting endemic species which will soon become extinct in the surveyed areas. Tropical marine invertebrate species did replace temperate species from 1982 to 2021 in the surveyed areas. Tropical marine invertebrate species did not replace temperate species from 1982 to 2021 in the surveyed areas. The temperate marine invertebrate species density and richness will recover with sufficient monitoring and resources.
