What is an example of a divergent evolution?

Divergent evolution occurs when related species develop unique traits due to different environments or selective pressures. A classic example of divergent evolution is the Galapagos finch which Darwin discovered that in different environments, the finches’ beaks adapted differently.

What is meant by divergent evolution?

: the development of dissimilar traits or features (as of body structure or behavior) in closely related populations, species, or lineages of common ancestry that typically occupy dissimilar environments or ecological niches The finches that Charles Darwin described in the Galapagos Islands are a classic example of …

What is divergent pattern?

A divergent pattern occurs when the characters of closely related species are more dissimilar in areas of sympatry than areas of allopatry, whereas in a convergent pattern, the characters are more similar in areas of sympatry than in areas of allopatry.

What is the difference between divergent and convergent speciation?

Speciation is a result of divergent evolution and occurs when one species diverges into multiple descendant species. Convergent evolution occurs when species have different ancestral origins but have developed similar features.

How can biologists measure homologous structures?

In genetics, homology is measured by comparing protein or DNA sequences. Homologous gene sequences share a high similarity, supporting the hypothesis that they share a common ancestor. Homology can also be partial: new structures can evolve through the combination of developmental pathways or parts of them.

What is divergent evolution explain with the help of example?

In divergent evolution, two or more distinct species share a common ancestor from which they diverged. A common example is a modern elephant and woolly mammoth. They share a common ancestor and yet evolved into two different species. Another example is the dog, the wolf, and the fox.

What is divergent adaptation?

Adaptation is divergent when one user or group’s adaptation causes a subsequent reduction in another user or group’s adaptive capacity in the same ecosystem. Similar to other studies, we find that expansion of farmland and the consequent loss of pastoral space are restricting pastoral adaptation.

What is divergence in geography?

A BROAD AREA WHERE two tectonic plates are colliding is a zone of convergence. An area where plates are moving apart is a zone of divergence.

What is divergent and convergent in math?

A convergent sequence has a limit — that is, it approaches a real number. A divergent sequence doesn’t have a limit. In many cases, however, a sequence diverges — that is, it fails to approach any real number.

What is the meaning of divergent and convergent?

Divergence generally means two things are moving apart while convergence implies that two forces are moving together. Divergence indicates that two trends move further away from each other while convergence indicates how they move closer together.

What is the difference between homologous and analogous structures?

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. The wings of a butterfly and the wings of a bird are analogous but not homologous.

How do you identify a homologous structure?

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. These structures are not analogous.
