An example of convergent evolution is the
similar nature of the flight/wings of insects, birds, pterosaurs, and bats
. All four serve the same function and are similar in structure, but each evolved independently.
What are 2 examples of evolution?
- Peppered Moth. This light-colored moth became darker after the Industrial Revolution due to the pollution of the time. …
- Brightly Colored Peacocks. …
- Darwin’s Finches. …
- Flightless Birds. …
- Pesticide Resistant Insects. …
- Blue Moon Butterfly. …
- Deer Mouse. …
- Mexican Cavefish.
What is an example of convergent evolution?
Convergent evolution is when different organisms independently evolve similar traits. For example,
sharks and dolphins
look relatively similar despite being entirely unrelated. … Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.
What is an example of convergent and divergent evolution?
Divergent evolution occurs when two separate species evolve differently from a common ancestor. … Convergent evolution occurs when species have different ancestral origins but have developed similar features. A good example of convergent evolution is
the similarities between the hummingbird and the hummingbird moth
.
Are birds and butterflies convergent or divergent?
Development of similar adaptive functional structures in unrelated groups of organisms is called
convergent
evolution. It shows analogy. Examples are wings of butterfly and birds, eyes of octopus and mammals, flippers of penguins and dolphins, etc.
What is an example of convergence?
The definition of convergence refers to two or more things coming together, joining together or evolving into one. An example of convergence is
when a crowd of people all move together into a unified group
. The point of converging; a meeting place. A town at the convergence of two rivers.
How does convergent evolution occur?
Convergent evolution occurs
when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures
. Traits that arise through convergent evolution are referred to as ‘analogous structures’. They are contrasted with ‘homologous structures’, which have a common origin.
Are humans still evolving?
It is selection pressure that drives natural selection (‘survival of the fittest’) and it is how we evolved into the species we are today. … Genetic studies have demonstrated
that humans are still evolving
.
Where do humans evolve from?
Humans first evolved in
Africa
, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
What are the 6 types of evolution?
Groups of species undergo various kinds of natural selection and, over time, may engage in several patterns of evolution:
convergent evolution, divergent evolution, parallel evolution, and coevolution
.
What’s the difference between divergent and convergent?
Whereas convergent evolution involves unrelated species that develop similar characteristics over time, divergent evolution involves
species with a common ancestor that change to become increasingly different over time
.
Is convergent evolution rare?
When multiple taxa independently evolved the same trait to cope with the same, or similar, environmental pressures, the trait is likely adaptive in that environment. … As each paper in this issue shows, convergent evolution at the phenotypic level
is rather common
.
What is the main difference between convergent and divergent evolution?
Convergent evolution
shows how species have evolved separately but have similar (analogous) structures
. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.
Are eyes convergent evolution?
The single-lens camera eye is found in vertebrates and in two groups of molluscs, octopus and squid. … Therefore,
the eyes of humans and octopuses
have been described as a typical example of convergent evolution (Fig. 2; Brusca and Brusca 1990; Futuyma 1997).
Are dolphins and sharks an example of convergent evolution?
We know that dolphins and sharks are not closely related, and they didn’t inherit their similar body shapes from a common ancestor. Their streamlined bodies, dorsal fins and flippers are the result of
convergent evolution
.
Are Penguins examples of convergent evolution?
Convergent evolution is this phenomenon where similar characters evolve independently in multiple lineages. … Cormorants, penguins, puffins, and gannets, each with minimal relatedness to the others, have
evolved
to have a “pygostyle” tail, which is straight and elongated.
