Why do species evolve during adaptive radiation?
Gentoo penguins present a potential mate with a pebble. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?
Which of the following must occur for speciation to happen?
Which lists the correct sequence of events for evolution to occur through isolation?
Which is most likely to happen to a population that becomes anatomically isolated from the rest of its species?
Scientists today can use many investigative methods to study evolution. Which method was developed after Darwin’s time?
Which of the following could result in speciation from biogeographic isolation?
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?
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?
A student argues that being separated geographically is the only way for speciation to occur. Why is he wrong?
