Homology refers to similarity between characteristics in different species of organisms. Bats and butterflies are quite different from each other, yet both have wings to fly; bats fly and whales swim, yet the bones in a bat's wing and whale's flipper are strikingly similar. While 'analogy' refers to different structures which perform the same function, 'homology' refers to similar structures which perform different functions. Prior to the advent of Darwinism, homology was attributed to the existence of archetypes: biological structures are similar because they conform more or less to pre-existing patterns.
Charles Darwin, however, offered a different explanation for homology. Darwin proposed that bats and whales possess similar bone structures, not because they were constructed according to the same archetype (which would imply design and thus intelligent causation), but because they were inherited from a common ancestor.
What else can I help you with?
Where are molecular homology found?
Homology is frequently found in organic chemistry.
What is the age of anatomical gift?
uniform anatomical gift act
What three criteria are used to determine whether something is homology?
The three criteria used to determine whether something is homology are similarity in structure, similarity in function, and evidence of shared ancestry. If two features meet these criteria, they are considered homologous.
Is a fly homologous?
Yes, flies are considered to be homologous to other insects. In evolutionary terms, homology refers to characteristics that are shared due to a common ancestry, and insects, including flies, share a common evolutionary history. This is supported by genetic, developmental, and anatomical evidence.
What is the meaning of anatomical?
Of or relating to anatomy or dissection; as, the anatomic art; anatomical observations.
What are The three types of homologies are?
The three types of homologies are anatomical homology (similar structure), developmental homology (similar embryonic origin), and molecular homology (similar genetic sequence). These homologies provide evidence of common ancestry and evolutionary relationships among different species.
In evolution the study of vertebrate forelimbs is related to evidence?
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
What is the study of vertebrate forelimbs is related to what evidence?
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
What is Primary homology?
proposed hypothesis of homology based on similarity.

What are types of evidence used to Classify organisms in systematic?
Physical homology, Genetic homology, and Ecological niche
Homology is evidence of what?
Evolution
How do you distinguish between a homology and a analogy?
Homology- Evolved from a common ancestor Analogous- 2 similar structures that evolved differently
