Although bats and birds are both vertebrates, they evolved flight separately. Bats move the air with thin skin rather than feathers. And the bones in bat wings reach the wingtip, while birds have short wing bones and long flight feathers..sorry if i havent answered your questions properly im only 12..:) but hopefully you would have learned something
They all have the same bones, albeit evolved to suit different needs.
This is 'convergent evolution', where completely different, unrelated organisms develop a similar feature.
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
This is an example of an observation, as it describes a physical characteristic of the bird.
Similar structures that evolved independently are called convergent evolution. This occurs when different species adapt to similar environmental pressures and develop analogous traits, even though they do not share a common ancestor that had those traits.
yes and also an example of evolution
Homologous structures indicate a common ancestor
Analogous structures are body parts that serve similar functions in different species but have different evolutionary origins. They arise from convergent evolution, where different species independently develop similar traits to adapt to similar environments or ecological niches. Examples include the wings of birds and insects, which serve the same purpose of flight but have different anatomical structures.
observation not inference
A bird has got its wings thanks to the evolution, life started in the sees and pools and found his way to the land, it's likely that the organisms who lived on land in someway splitted in another group for flying animals. in the years after that wings have developed furtherlike they're now in most of the birds :)
Analogous structures are features of two different species that are similar in how the function, but the structure of the two features is different. The wings of an insect and the wings of a bird are analogous structures.
The possessive form of the noun bird is bird's.example: We sat quietly and listened to a bird's call.
