Difference Between Homology and Homoplasy

Homology is similarity that reflects common descent and ancestry. Homoplasy is similarity (some might say superficial similarity) arrived at via independent evolution.

What is the difference between homology and convergent evolution?

Homology is the evolution of similar structures in species evolved from a recent common ancestor whereas convergent evolution is the independent evolution of similar structures in unrelated organisms.

What is the difference between homology and analogy?

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. ... Analogous structures are structures that are similar in unrelated organisms.

What is an example of homology?

A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.

What does homology mean?

Homology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor. ...

What are 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. Some aspects of the lens of eyes also evolved independently in various animals.

What is a convergent trait?

Convergent evolution is when different organisms independently evolve similar traits. ... Biologists call this process — when two organisms share characteristics that they didn't jointly inherit from a common ancestor — convergent evolution.

What is the strongest evidence of evolution from a common ancestor?

Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

What kind of evolution gives rise to analogy?

Convergent evolution gives rise to analogous structures.

What are 3 examples of homologous structures?

Homologous Structures Humans Share With Animals

• A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures. ...
• The tailbone in human beings is so-named because it is a homologous structure to the beginning of many animals' tails, such as monkeys.

What are the three types of homology?

Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.

Which observations are examples of homologies?

Examples of Homology in Animals and Plants

• The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. ...
• The forelimbs of a frog, a bird, a rabbit and a lizard look very different because they have evolved differently to account for the specific lifestyles of each animal.

What is a homologous trait?

A homologous trait is any characteristic which is derived by evolution from a common ancestor. This is contrasted to analogous traits: similarities between organisms that were evolved separately. The term existed before 1859, but got its modern meaning after Darwin established the idea of common descent.
