BIOGEOGRAPHIC ISOLATION

Why do species evolve during adaptive radiation? to fill different niches to create variation to become reproductively isolated to provide evidence of evolution

Which of the following is the best definition of biogeographic isolation? the separation of members of a species through geographical or biological forces the separation of members of different species through geographical or biological forces the separation of populations of different species through time the separation of members of a species through anatomical forces

Scientists today can use many experimental methods to study evolution. Which method was developed after Darwin's time? DNA comparisons observations fossils experimentation

Cardueline finches can be found in many areas of the world, including North America and Asia. Hawaiian honeycreepers, which are found only in Hawaii, have been found to have DNA commonalities with this group of finches that indicate they have a common ancestor. Which mechanism might have led to the appearance of the Hawaiian honeycreeper? anatomical isolation temporal isolation geographical isolation behavioral isolation

The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern California. Their typical breeding season lasts from January to March. The foothill yellow-legged frog, or Rana boylii, is found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to July. What mechanism might keep Rana aurora and Rana boylii from mating? anatomical isolation temporal isolation geographic isolation behavioral isolation

Which of the following could result in speciation from biogeographic isolation? the isolation of two populations of the same species the isolation of two individuals of the same species the isolation of two populations of different species the isolation of two individuals of different species

Gentoo penguins will present a mate with a pebble that they find to attract a mate. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate? temporal isolation behavioral isolation geographical isolation anatomical isolation

Which lists the correct sequence of events for evolution to occur through isolation? founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results genetic changes occur, founding population arrives, reproductive isolation results, biogeographic isolation occurs biogeographic isolation occurs, founding population arrives, genetic changes occur, reproductive isolation results founding population arrives, genetic changes occur, biogeographic isolation occurs, reproductive isolation results

Which is most likely to happen to a population that becomes anatomically isolated from the rest of its species? The entire species will become extinct. The population will become a separate species over time. The population will breed with a different species nearby. The entire species will continue to have viable offspring together.

Marsupials, such as kangaroos, koalas, and wombats, are mammals that care for their newborn young in a pouch. All marsupials that are found in Australia are thought to have evolved from a single species that migrated to the island and then adapted to the various niches. What does this example illustrate? behavioral adaptation adaptive radiation geographic isolation population explosion

What is the main difference between adaptive radiation and other forms of speciation? Adaptive radiation is a mechanism for evolution. Adaptive radiation happens over a relatively short time. Adaptive radiation requires a founding population. Adaptive radiation occurs only on islands.

Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe? behavioral temporal geographical anatomical

Horses and donkeys can mate, but they produce a mule, which is always a sterile animal. This means that they cannot produce viable offspring and are ______________ isolated.

Which of the following must occur for speciation to happen? geographic isolation reproductive isolation temporal isolation behavioral isolation
