Zorluk: OrtaContextual Examples

Read the following passage about evolutionary biology. Based on the text, match each specific biological example (left) to the broader evolutionary strategy it is explicitly used to illustrate (right).

In the study of evolutionary biology, mimicry serves as a compelling illustration of natural selection, taking on several distinct functional forms. The most traditionally cited form, Batesian mimicry, occurs when a harmless species adopts the warning signals of a noxious species to deter predators. The classic illustration of this is the hoverfly, which lacks a stinger but sports the bold yellow and black banding of a yellowjacket wasp, thereby deceiving avian predators. Conversely, Müllerian mimicry involves two or more genuinely noxious species that have evolved to share similar warning signals, creating a mutually beneficial reinforcement of the predator's learned avoidance. The convergence of wing patterns among various species of Heliconius butterflies perfectly exemplifies this mutualistic defense strategy. Beyond defensive strategies, mimicry can also be predatory. In aggressive mimicry, a predator deceptively resembles a benign entity or a resource to lure unsuspecting prey. The female Photuris firefly, for instance, imitates the mating flashes of females from the Photinus genus to attract and consume Photinus males. Finally, automimicry involves a species developing morphological features that resemble other parts of its own body, often to redirect a predator's attack toward a less vulnerable area. The prominent false eyespots on the posterior wings of the hairstreak butterfly serve to deflect bird strikes away from the insect’s critical head region, thus increasing the chance of survival despite minor wing damage.

  • The convergent wing patterns of Heliconius butterfliesEstablishing a shared defense system to reinforce predator avoidance
  • The mating flashes emitted by the female Photuris fireflyExploiting the reproductive behavior of another species for predatory gain
  • The posterior eyespots on the hairstreak butterflyMisdirecting a predator's attack by creating anatomical confusion

Cevap

The hoverfly illustrates benefiting from the protective reputation of an unrelated, dangerous species. Heliconius butterflies illustrate establishing a shared defense system to reinforce predator avoidance. The female Photuris firefly illustrates exploiting the reproductive behavior of another species for predatory gain. The hairstreak butterfly illustrates misdirecting a predator's attack by creating anatomical confusion.
Each example provided in the passage corresponds to a distinct form of biological mimicry. The correct matches strictly link the specific organism (the contextual example) to the precise evolutionary strategy the author uses it to illustrate.

Adım Adım Çözüm

1
Locate the mention of the hoverfly in the passage.
The hoverfly is cited as a classic illustration of Batesian mimicry, where a harmless species adopts warning signals of a noxious one.
To determine the conceptual function of the hoverfly example.
2
Locate the reference to Heliconius butterflies.
They exemplify Müllerian mimicry, a mutualistic strategy where genuinely noxious species share warning signals to reinforce predator avoidance.
To map the second example to its specific evolutionary abstraction.
3
Examine the role of the female Photuris firefly in the text.
It is an example of aggressive mimicry, imitating mating flashes to attract and consume prey.
To identify the illustrative purpose of the firefly example.
4
Identify the purpose of the hairstreak butterfly's eyespots.
They serve as automimicry, deflecting bird strikes away from the critical head region.
To match the final example to its broader evolutionary function.
