An example of homologous structures are
the limbs of humans, cats, whales, and bats
. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.
Which structures are homologous quizlet?
dolphin’s flipper, bird’s wing, cat’s leg, and the human arm
are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals.
Which of these are homologous structures?
A
dolphin’s flipper, a bird’s wing, a cat’s leg, and a human arm
are considered homologous structures. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.
What are homologous structures called?
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 are 3 examples of homologous structures?
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 do homologous structures indicate?
Homologous structures indicate that
the species came from a common ancestor and are related through evolution
.
What are examples of analogous structures?
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.
Which are examples of analogous structures quizlet?
A beetle wing and a bat wing were both evolved from different ancestors
to achieve the same purpose. They do not have the same underlying structure. Therefore, they are an example of analogous structures.
What do homologous and analogous structures have in common quizlet?
Structures are similar, which shows a common ancestor. Analogous structures are when
two organisms have different structures but serve a similar function
. … Homologous structures share an ancestor but serve a different function but analogous structures serve a similar function but do not share an ancestor.
Are tails homologous structures?
Monkeys, cats, rats and other mammals have tails. … The fact that the structure of the human coccyx so closely resembles that of an animal tail gives scientists reason to link it to a common ancestor between mammals and humans. Due to this link,
the mammalian tail and the human coccyx are homologous structures
.
How do homologous structures develop?
Homologous structures are structures that are
similar in related organisms because they were inherited from a common ancestor
. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. … They inherited this pattern from a common ancestor.
What are analogous structures?
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.
What is homologous structures in evolution?
Homologous structures are
structures that are similar in related organisms because they were inherited from a common ancestor
. These structures may or may not have the same function in the descendants.
What are examples of homologous and analogous structures?
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. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.
What is the function of homologous structure?
What is a homologous structure? It is an example of an organ or bone with similar underlying anatomical features found in different animals. These structures
support the idea that the different animals descend from a common ancestor and serve as evidence of evolution
.
