Are homologous structures an example of convergent evolution?

Are homologous structures an example of convergent evolution?

Examples of convergent evolution include the relationship between bat and insect wings, shark and dolphin bodies, and vertebrate and cephalopod eyes. Analogous structures arise from convergent evolution, but homologous structures do not.

What is a homologous structure in reference to evolution?

Homologous structures are similar structures that evolved from a common ancestor.

What is divergent evolution examples?

Divergent evolution is commonly defined as what occurs when two groups of the same species evolve different traits within those groups in order to accommodate for differing environmental and social pressures. Various examples of such pressures can include predation, food supplies, and competition for mates.

Is homology and convergent evolution the same?

Homology refers to the existence of shared ancestry between a pair of structures or genes in different taxa while convergent evolution refers to the independent evolution of similar features in species of different periods in the timeline.

How does homologous structures support evolution?

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.

How homology is different from convergent evolution?

The main difference between homology and convergent evolution is that homology is the evolution of the similar structures in species evolved from a recent common ancestor whereas convergent evolution is the independent evolution of similar structures in unrelated organisms.

Which one of the following is an example for homologous organs based on divergent evolution?

Wings in birds and bats. Hint: When two structures are similar in morphology or genetic sequence and are derived from a common origin or ancestor, it is said to be homology and the structures are known as homologous structures. Homologous organs or structures generally result due to divergent evolution.

Are gills and lungs analogous?

The organs which have similar functions but are different in their structural details and origin are called analogous organs. Similarly, gills of prawn and lungs of man, both are respiratory organs yet they have very different basic structure.

What characteristics describe homologous structures?

Homologous Structures Definition. Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function.

Which of the following best describes how homologous structures support the theory of evolution?

Which statement best describes how homologous structures evolve? A basic structure inherited from a common ancestor may evolve different variations in different species.
