- The first step leading to allopatric speciation is (a) hybrid inviability (b) hybrid breakdown (c) adaptive radiation (d) geographic isolation (e) paedomorphosisarrow_forwardExplain into details the concept of speciation .arrow_forwardExplain how the map represents a visual example of the process of speciation.arrow_forward
- What is a reason that speciation can occur? Organisms within a species are brought into closer proximity by a physical barrier. Organisms within an ecosystem make adaptions that involve different breeding times or interactions. Organisms develop traits that are not beneficial to their survival, and these traits are passed from generation to generation. Organisms develop traits that are beneficial and pass on the same traits to all future generations within the same species.arrow_forwardPre-mating barriers to reproduction often evolve relatively late in the process of speciation. Describe why post-mating reproductive barriers typically evolve before pre-mating barriers.arrow_forwardwhich statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forward
- Define allopatric speciation and provide a hypothetical situation through which it could occur.arrow_forwardIn what theory of speciation do new species emerge within the geographic range of their ancestors?arrow_forwardSpeciation can occur when two populations of a species become separated from each other. What is the best explanation for why speciation occurs?arrow_forward
- Speciation can occur rapidly between diverging populations, yet the time between speciation events is often more than a million years. Explain this apparent contradiction.arrow_forwardHow does one species diverge from another? (When do we call a group a new species—and how does that process happen?) Using anole lizards or another very specific example(s), compare and contrast microevolutionary processes with speciation. As you discuss speciation, be sure to compare and contrast sympatric speciation with allopatric speciation and say whether the example you’ve chosen is allopatric or sympatric.arrow_forwardDescribe the steps necessary for geographic isolation to lead to speciation.arrow_forward
