What evolved independently?

What evolved independently?

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.

What structures have a similar function but are structurally different because they evolved independently?

Analogous / Convergent Structures Some biological characteristics are analogous (also called “convergent”), which means that they serve the same function in different species but they evolved independently rather than from the same embryological material or from the same structures in a common ancestor.

Do homologous structures evolve independently?

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. They also have the same function. However, wings evolved independently in the two groups of animals.

Do species evolve independently?

Sometimes, similar phenotypes evolve independently in distantly related species. However, the wings of bats and insects have evolved from very different original structures. This phenomenon is called convergent evolution, where similar traits evolve independently in species that do not share a recent common ancestry.

What are some reasons that similar traits might arise independently in species that are only distantly related?

What are some reasons that similar traits might arise independently in species that are only distantly related? Can you think of examples among familiar organisms? A reason that they might arise independently is because of convergent evolution.

What are types of evolution?

shows the three main types of evolution: divergent, convergent, and parallel evolution.

Which are structures with similar function but different structure?

In evolutionary biology, analogous structures are defined as biological structures having similar or corresponding functions but not from the same evolutionary origin. In other words, species use these biological structures for the same purpose and yet these species are from unrelated evolutionary lines.

What types of features have similar structures but different functions?

Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.

What are the similarities between homologous and analogous structures?

Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale’s front flipper are homologous to the bones in the human arm.

How are the forelimbs similar?

The forelimbs of all mammals have the same basic bone structure. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside. They also have the same function.

What are the example of convergent?

Examples of Convergent Boundaries The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. The collision of this oceanic and continental plate was how the Andes Mountains were formed.

How is this similar to some evidence for evolution?

How is this similar to some evidence for evolution? Similarities can be seen among related organisms, which shows common ancestry. They are both explanations of the rate of evolutionary change.
