Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Distinguish between homologous structures and analogous structures?
Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but different external structure because of their different functions. Analogous structures have similar external structure because of similar functions, but dissimilar internal structure. An example of analogous structures would be the wings of an insect and a bird.
Structures that have similar structure and function but different evolutionary origins are called?
It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
What are the difference between homologous organ and analogous organ?
Homologous organs have similar embryonic origin and basic structure whereas Analogous organs have different embryonic origin and basic structure. Homologous organs may look different and may perform different function; e.g., forelimb of a man and flipper of a whale. Whereas Analogous organs look alike and perform same functions; e.g., Wings of birds and insects.
What featureswith the same functions in two organism but different recent ancestors?
Analagous structures

What is the relationship between homologous structure and analogous structure?
Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.

What are structures that have different functions in different species but develop from the same embryonic tissue?
Homologous structures
How do analogous structures and homologous structures differ?
Homologous features of animals are a lot more recent in contrast to evolution, where as analogous dates far back. Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to allow recent evolution comparisons while analogous consists of wings of a bee and a bird, which are completely different. When trying to determine evolutionary relationship between two species, biologists concentrate on homologous features, as analogous features would be considered useless in this case.
What is homologous organs and analogous organ?
Homologous organs have similar looking structure and similar origin but different functions . Whereas analogous is just the opposite analogous organs are those that have similar function but different origin and structure
Compare homologous and analogous structures?
Homologous structures are similar in structure but different in function, indicating shared ancestry (such as the bones in the limbs of humans and bats). Analogous structures have similar functions but different origins, suggesting convergent evolution (like the wings of birds and insects).
Analogous and homologous?
1. HOMOLOGOUS ( morphological and anatomical evidences ) .These are the organs that have same basic structural plan and origin but different functions. 2. ANALOGOUS These are the organs that have different origin and structure plan but same function
What is the difference between a homologous structure and a analogous structure?
Homologous structures are different forms of animal anatomy which have come from the some origin (a common ancestor), these can be extremely different in appearance and function. For example a bats wing, a seals flipper and a human arm all have common bone and muscle structures suggesting that they all derived from a common ancestor. Vestigial structures are parts of the anatomy which have lost their original function through the evolutionary process and no longer obtain a major functional role in that animals life. For example in human the appendix's original function was to break down cellulose in plant material, other vestigial functions in humans include the coccyx (tailbone) and ear muscles.
What homologous structures in different species evidence of?
Homologous structures in different species are evidence of a common evolutionary ancestry. These structures have a similar origin, but may have different functions in different species. Studying homologous structures helps researchers understand how species have diverged and evolved over time.
What is the difference between analogous and homologous?
Analogous means that the structures have different origins, but they do the same things. Homologous means the opposite: that they have the same origins but are adapted to do different functions.
