What type of structure is represented by the wing of a bird and the wing of a butterfly?

What type of structure is represented by the wing of a bird and the wing of a butterfly?

analogous organs
Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous, but not homologous.

Is a penguin wings homologous?

But not all bird forelimbs are wings. So penguin flippers are homologous to an analogous structure to butterfly wings, but are not themselves analogous to butterfly wings!

What are penguin wings called?

A penguin’s wings are designed perfectly however for gliding through water. They are often referred to as flippers because of their shape. The wings are super stiff and penguins can actually rotate them in different directions at the same time! This helps them act as the perfect paddle to help catch their prey.

Are bat wings and bird wings homologous?

Sometimes it is unclear whether similarities in structure in different organisms are analogous or homologous. An example of this is the wings of bats and birds. These structures are homologous in that they are in both cases modifications of the forelimb bone structure of early reptiles.

What is the function of butterfly wing?

A butterfly’s wings are used for flight, but also have many other functions. Patterns on the wings can help camouflage the butterfly, warn predators that a butterfly is poisonous, surprise or distract predators with flashy displays, and help a butterfly attract and communicate with other butterflies of its species.

What is the function of bird wing?

Wings. The shape of a bird’s wing is important for producing lift. The increased speed over a curved, larger wing area creates a longer path of air. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift.

Why are butterfly and bird wings analogous structures?

Analogies are similar characteristics shared by two different organisms because of convergent evolution. For example, the wing of a dove and the wing of a butterfly are analogous; the bird lineage and the insect lineage evolved wings independently of one another.

Is heart of man and bird homologous?

Organs that are structurally similar and functionally different are called homologous organs. The hearts of birds and mammals show similarities in the basic structure (possess 4 chambers), but functionally the heart of humans is more complex than birds.

Why can’t penguins fly despite having wings?

Scientists believe penguins can’t fly because they likely had little or no threat from predators in their past. That means they never evolved to fly because they didn’t have anything to fly away from. Instead, these birds evolved to become more aquatic to better survive in their habitat.

Do bats and butterflies have a common ancestor?

Bats (Vertebrata) are deuterostomes. The ancient last common ancestor of the butterfly and the bat had nothing like wings. This tells us that the wings of the butterfly and the wings of the bat evolved independently, long after their ancestral lineages diverged from the gastrula-like ancestor.

What are 3 interesting facts about butterflies?

10 Fascinating Facts about Butterflies

  • Butterfly wings are transparent.
  • There are almost 20,000 butterfly species.
  • Butterflies use their feet to taste.
  • Butterflies only live for a few weeks.
  • The most common butterfly in the US is the Cabbage White.
  • Some butterfly species migrate from the cold.

How are the wings of a Penguin used?

Penguin wings are paddle-like flippers used for swimming. The motion of the flippers resembles the wing movements of flying birds, giving penguins the appearance of flying through water. The wing and breast muscles are well developed, to propel penguins through water – a medium much denser than air.

What kind of feathers does a penguin have?

It is a hard, rigid paddle covered with tiny stiff feathers that are not waterproof (unlike the feathers on the rest of a penguin body). A penguin flipper has a shape comparable to an airplane’s wing. Birds normally have hollow bones, since little weight helps in flying.

What kind of shape does a penguin Flipper have?

A penguin flipper has a shape comparable to an airplane’s wing. Birds normally have hollow bones, since little weight helps in flying. Due to the shape of their wings, normal birds only gain speed by the down stroke. Penguins however have solid bones, which are heavier.

What kind of structure does an emperor penguin have?

Emperor Penguins. The penguin has a special type of structure to help it adapt to its conditions around it. For an example the penguin has a small flap like structure located in between its legs. This is called the Brood pouch and the Brood pouch’s function is to keep his and her young warm.

What do penguins do with the wings they have?

Penguins are classified as birds and like other birds have wings too, but these wings are not used for flying. Penguins are carnivorous sea birds and spend a lot of their time hunting for smaller fish under the ice sheets of the Southern Hemisphere.

Why are penguins called flippers and not birds?

Penguins are classified as birds and like other birds have wings too, but these wings are not used for flying. Penguins are carnivorous sea birds and spend a lot of their time hunting for smaller fish under the ice sheets of the Southern Hemisphere. The wings of a penguin are called “Flippers” because of the way the Penguins use them.

How did Penguins evolve from birds to swimming?

It is believed that over decades of using their wings, penguins have evolved from using their wings from flying to swimming. Penguins are classified as birds and like other birds have wings too, but these wings are not used for flying.

How are penguins able to communicate with each other?

The penguins use their wings for communicating with each other too. They are seen touching another penguin’s flippers displaying courtship behavior. Birds have various ways in which they communicate when they want to attract a receptive mate. Penguins keep an eye out for a suitable mate and slightly tap flippers to communicate interest in mating.
