Convergent evolution is when non-related organisms evolve extremely similar characteristics completely separately. They develop these characteristics because they live in similar environments or ecological niches. Similar environments impose similar challenges, and traits improving survival are favoured.

Similarly one may ask, what is the most confused animal?

Leopards inhabit parts of Africa and Asia, and Jaguars are found in South and Central America, as well as occasionally the southwestern United States. Here are a few other ways to distinguish them. Both cats have clusters of dark spots on their fur, but jaguars have smaller spots inside each cluster.

Also Know, how can two species that look very different from each other be more closely related?

1 Answer. Nature selects the traits that give an organism an advantage over others. These traits are found in many other organisms. What they evolved from differs, but their mutations remain the same/similar.

What is the difference between a animal and a mammal?

The main difference between animal and mammal is that the animal refers to any type of organism classified under kingdom Animalia whereas a mammal is a type of animal that has mammary glands and a body covered with fur. Furthermore, not all animals are vertebrates but, mammals are vertebrates.

Who are species?

A species is a group of organisms that can reproduce and create fertile offspring. In general, individuals of a species are recognizable because they are similar in form and function. In the past, species were classified according to their shape.

Are vestigial structures convergent or divergent?

Divergent Evolution – The evolution and accumulation of different traits between groups, which results in the formation of new species. Vestigial Structures – A structure or attribute, which is present within an organism but has lost its ancestral function.

What are analogous structures?

Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.

What are 2 examples of convergent evolution?

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.

Are analogous structures convergent or divergent?

Analogous structures arise from convergent evolution, but homologous structures do not. Convergent evolution is the opposite of divergent evolution, in which related species evolve different traits.

What is it called when one species evolves into many?

It normally takes many generations to see major differences, but it's all evolution. This process where evolution gradually creates major change in a species or splits it into two or more genetically separate groups, is called speciation.

What is a homologous trait?

Homologous traits are traits that are similar to one another due to shared ancestry. As species adapt to their environments and evolve over time, these traits may change in appearance and in function, but ultimately they still share the structure, genetics, or embryonic structure of their common ancestor.

What is divergent evolution examples?

One of the most famous examples of divergent evolution is the case of Darwin's Finches. During Darwin's travels to the Galápagos Islands he discovered several different species of finch that shared a common ancestor.

What is a convergent trait?

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

How do analogous structures evolve?

Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.

Why are wings considered analogous structures?

For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.

Are bat wings and bird wings homologous or Homoplastic structures?

Wings in birds and bats have evolved separately in each group; these features are homoplastic as wings. However, they are homologous as forearms, because they evolved in each case from the front limbs. Characters change from one state to another through the process of evolution.

How do analogous structures arise in different species?

6. How do analogous structures arise in different species? A) A basic structure inherited from a common ancestor develops different variations in different species. Structures developed by an ancestral species are found in several distantly releated species.

How are convergent and divergent evolution similar?

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.

What is the difference between homology and convergence?

Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Functionally similar features that have arisen through convergent evolution are analogous, whereas homologous structures or traits have a common origin but can have dissimilar functions.

What type of evolution do you think typically illustrates homologous structures?

Structures that are the result of convergent evolution are called analogous structures or homoplasies; they should be contrasted with homologous structures, which have a common origin.

What is the difference between Homoplasy and analogy?

is that homoplasy is a correspondence between the parts or organs of different species acquired as the result of parallel evolution or convergence while analogy is a relationship of resemblance or equivalence between two situations, people, or objects, especially when used as a basis for explanation or extrapolation.
