Analogous Structures
What are Analogous Structures
• Analogous structures are those structures in
different species which perform the same
function, have similar appearance and
structure but are not evolved together;
therefore do not share a common ancestor.
History of Analogous Structures
• Carolus Linnaeus first began the classification
of species with taxonomy. He started grouping
all similar looking species together. This led to
the wrong classification of species because all
similar looking structures are not evolved at
the same time. Just because species look alike
does not mean they are evolutionarily related.
Examples of Analogous Structures
• Analogous structures evolve due to
convergent evolution when different
organisms adapt to the same environment.
1- Wings of an insect and wings of a bird.
2- Fins of a fish and a penguin.
3- Limbs of humans, horses and dolphins.
Conclusion
• It does not depend only on appearance to
determine which species are closely related, it
takes more than just looks. However,
analogous structures act as evidence that the
theory of natural selection persists and the
adaptations accumulate over time.
