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.
What is the main difference between a homologous trait and an analogous trait?
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.
What is difference between homologous and analogous?
| Homologous Structure Analogous Structure | They are developed as a result of the adaptation to a different environment They are developed as a result of the adaptation to a similar environment |

What is the difference between homologous and analogous structures quizlet?
Homologous structures share a common ancestry , but not necessarily a common function. Analogous structures share a common function, but do not share a common ancestry. ... Similar patterns of embryological development provide further evidence that organisms have descended from a common ancestor.
What are analogous traits?
Analogous structures are traits shared by species that live in the same environment but are not related to each other . Learn what species have analogous structures through the examples provided.
What are the examples of analogous?
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
What are homologous analogous organs give examples?
(a) Analogous Organs: Organs which performs similar function but are different in structure and origin. Example – wings of a bird and wings of an insect . Homologous Organ: Organs which have different functions but similar structure and origin. Example – fore arm of frog, lizard, bird and human.
What is a homologous trait?
Homologies are traits present in two or more organisms that were inherited from the common ancestor of those organisms . The human five-fingered hand and the five-toed foot of a lizard, for example, were both inherited from our common ancestor that lived more than 300 Mya (Fig.
Why are wings analogous?
Bird and bat wings are analogous — that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight . Analogies are the result of convergent evolution.
What structures are analogous to one another?
Analogous structures are similar structures in unrelated organisms . These structures are similar because they do the same job, not because they share common ancestry. For example, dolphins and sharks both have fins, even though they aren’t related. Both species developed fins because of how (and where) they live.
What is an example of homologous structures?
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 . ... An example of this are the wings of a bat and the wings of a bird.
What does analogous structure mean?
Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.
Do analogous structures indicate common ancestry?
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
What are analogous organs give examples?
Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings .
What are some examples of analogous colors?
- Yellow, yellow-green, green.
- Violet, red-violet, and red.
- Red, red-orange, orange.
- Blue, blue-violet, violet.
What is an analogous relationship?
a similarity between like features of two things , on which a comparison may be based: the analogy between the heart and a pump. ... an analogous relationship.
