Question

classify the following examples based on what phenomenon they describe. choices can be used more than once or not at all. a galápagos island contains 13 finch species, each adapted to their particular niche, all of which evolved from a single population. both spiders and snakes have fangs with which to kill and immobilize their prey. a species of orchid is pollinated only by the male of a single species of wasp. moths have long probosci necessary to glean nectar from the long - tubed flowers from which they feed and pollinate. two different species of fish within a river give rise to several new species, all with a streamlined shape, necessary for navigating the rough river currents of their habitats. the wings of a bat contain the same bone structure as the arms of humans. coevolution adaptive radiation convergent evolution

Explanation:

To solve this, we analyze each example based on the definitions of coevolution, adaptive radiation, and convergent evolution:

Coevolution

• Moths have long probosci...: Moths and flowers evolved together (moths’ probosci for flower nectar, flowers rely on moths for pollination).
• A species of orchid is pollinated...: Orchid and wasp evolved together (orchid depends on wasp for pollination, wasp likely depends on orchid for reproduction).

Adaptive Radiation

• A Galápagos island contains 13 finch species...: A single finch population evolved into 13 species, each adapted to a unique niche (diversification from a common ancestor).
• Two different species of fish...: Two fish species gave rise to several new species with a shared adaptation (streamlined shape) for their environment (diversification from related ancestors).

Convergent Evolution

• Both spiders and snakes have fangs...: Spiders and snakes (unrelated) evolved similar structures (fangs) for the same function (killing prey).
• The wings of a bat...: Bat wings and human arms (unrelated lineages) share the same bone structure (homologous structures, but here convergent in function? Wait, no—bat wings and human arms are actually homologous (same ancestor), but the question’s options: wait, no, convergent evolution is unrelated species evolving similar traits. Wait, correction: Bat wings and human arms are homologous (same bone structure from a common ancestor), but the other example (spiders and snakes) is convergent. Wait, recheck:

Wait, Convergent Evolution is when unrelated species evolve similar traits due to similar environments/functions.

• Spiders (arthropods) and snakes (reptiles) are unrelated, but both evolved fangs (similar trait for hunting) → convergent.
• Bat wings (mammal) and human arms (mammal) are homologous (same ancestor), but maybe the question considers it? Wait, no—bat wings and human arms have the same bone structure (homology), but the other option: maybe the question’s “convergent” includes this? Wait, no, convergent is for unrelated. Let’s re-express:

Final Classification:

• Coevolution:
• Moths have long probosci necessary to glean nectar from the long - tubed flowers from which they feed and pollinate.
• A species of orchid is pollinated only by the male of a single species of wasp.
• Adaptive Radiation:
• A Galápagos island contains 13 finch species, each adapted to their particular niche, all of which evolved from a single population.
• Two different species of fish within a river give rise to several new species, all with a streamlined shape, necessary for navigating the rough river currents of their habitats.
• Convergent Evolution:
• Both spiders and snakes have fangs with which to kill and immobilize their prey.
• The wings of a bat contain the same bone structure as the arms of humans. (Note: This is actually homology, but based on the question’s options, it is classified here as convergent evolution might be a misclassification, but following the question’s context.)

Answer:

(Filled into the Boxes):
