What else can I help you with?
These are physical features shared by organisms with common ancestry they may have the same structure but different functions developmentally mature organisms?
These physical features are known as homologous structures. They suggest a common evolutionary history among organisms and may have originated from the same structure in a shared ancestor. Despite potentially serving different functions in mature organisms, their structural similarity points to a shared genetic relationship.
A shared derived characteristic is usally a?
a characteristic---- usually a homologous structure----shared by all organisms in a group
What does homogolous mean?
Homologous refers to similarities in structure or function between different species that suggest a common evolutionary origin. This term is often used to describe traits or features that are shared due to being inherited from a common ancestor.
What is A Characteristic -usually a homologous structure- shared by all organisms in a group?
A characteristic typically shared by all organisms in a group is known as a synapomorphy, which is a derived trait that reflects a common ancestry. These homologous structures can include specific anatomical features, genetic sequences, or developmental patterns that have evolved over time. For example, the presence of vertebrae in all vertebrates is a synapomorphic trait that unites this diverse group of animals. Such shared characteristics help scientists classify and understand evolutionary relationships among different organisms.
What are the differences between a synapomorphy and a homologous trait?
A trait shared by at least two and perhaps more taxa and devolving on common ancestry is synapomorphy. A homologous trait is quite similar. The forelimbs of all tetrapods are devolved from common ancestry and would be traits shared by many taxa and homologous traits. Cladists use the word synapomorphy more to show closer relationships. Pliesiomorphy is the word cladists use to show more ancient relationships.
What is the similar features that originated in a shared ancestor?
Homologous structures are features that originated in a shared ancestor, such as the bones in the limbs of vertebrates. These features may have different functions in modern organisms but have similar underlying structures due to their common ancestry.

What trait shared with a common ancestor?
Homologous structures
What do scientist call such similar structuresslide1?
Scientists may refer to similar structures as homologous structures, which are anatomical features that have a common evolutionary origin, despite potentially serving different functions in different species. These structures can provide evidence of a shared ancestry between different organisms.
What features are shared by most bacteria?
Most bacteria are unicellular, have a cell wall, reproduce asexually through binary fission, and have a single circular chromosome.
How are homologous evidence for evolution?
Homologous structures are evidence for evolution because they indicate that different species share a common evolutionary ancestor. These structures have similar underlying anatomical or genetic features, suggesting a shared evolutionary history. For example, the bones in the limbs of vertebrates all share a common anatomical structure, indicating a shared evolutionary origin.
A shared derived characteristic is usally a?

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.
How do homologous structures provide evidence of species changing over time?
Homologous structures are similar body parts in different species that suggest a common evolutionary ancestor. These structures provide evidence of species changing over time because they indicate that different species have evolved from a shared ancestor and adapted to different environments. By studying homologous structures, scientists can trace the evolutionary history of species and understand how they have changed over time.
What does homogolous mean?
Homologous refers to similarities in structure or function between different species that suggest a common evolutionary origin. This term is often used to describe traits or features that are shared due to being inherited from a common ancestor.
3 Are the shell of a turtle and that of a snail homologous or analogous?
analogous because the two features are similar in function yet did not occur due to a shared ancestry. it would be considered homology if the two organisms were somehow related.
