How does vestigial structures indicate that present day organisms are different from their ancient ancestors?
The biologist might infer that at one point in history the animal's ancestors had this limb. But as time went by the ancestors used to limb less, therefore, shrinking the limb or completely getting rid of it.
What else can I help you with?
How do vestigial structures indicate that present day organisms are different from their ancient ancestors?
Vestigial structures are remnants of organs or features that were functional in an organism's ancestors but have reduced or lost their original function over time. The presence of these structures suggests that present-day organisms have undergone evolutionary changes from their ancient ancestors. These structures provide evidence for common ancestry and support the theory of evolution.
Vestigial structures in organisms look the same?
Vestigial structures are remnants of traits that were functional in the organism's ancestors but are no longer used. While these structures may appear similar across different organisms, the specific functionality they once served may vary. The similarity in appearance may be due to shared ancestry rather than a current common function.
Why do vestigial structures persist in modern organisms This ans?
Vestigial structures persist in modern organisms because they are remnants of evolutionary ancestors that served a purpose but have since lost their original function. While these structures may no longer be essential for survival, they can still be retained in the genome due to a lack of strong selective pressure for their removal. Additionally, some vestigial traits may have retained minor functions or benefits that are not immediately apparent, allowing them to persist through generations.
What are remnants of structures that served important functions in the organisms ancestors is it homologous analogous vestigial or neither?
Remnants of structures that served important functions in an organism's ancestors are referred to as vestigial structures. These features may have lost their original function through evolution but can still be observed in the organism. Examples include the human appendix or the pelvic bones in whales, which reflect their evolutionary history. In contrast, homologous structures share a common ancestry, while analogous structures arise from convergent evolution and do not share a common ancestor.
Do plants have vestigial organ?
No, plants do not have vestigial organs. Vestigial organs are remnants of structures that were once functional in evolutionary ancestors but are no longer needed. Since plants do not have a common ancestor with animals, they do not have vestigial organs.

How do vestigial structures indicate that present day orgnaisms are different from their ancient ancestors?
I don't know lol
How do vestigial structures work?
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.
What is the term for structure that has no use in an organism?
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
How do vestigial structures provide evidence that we evolved from organisms that existed in the past?
Vestigial structures are anatomical features that have lost their original function in an organism but are still present. These structures often have similarities to functional structures in related organisms, suggesting a shared evolutionary history. By studying these vestigial structures, scientists can infer how organisms have changed over time through the process of evolution.
Why do vestigial structures persist in modern organisms This ans?
Vestigial structures persist in modern organisms because they are remnants of evolutionary ancestors that served a purpose but have since lost their original function. While these structures may no longer be essential for survival, they can still be retained in the genome due to a lack of strong selective pressure for their removal. Additionally, some vestigial traits may have retained minor functions or benefits that are not immediately apparent, allowing them to persist through generations.
Why do vestigial structures such as the human appendix exist?
Vestigial structures like the human appendix exist because they were once functional in our evolutionary ancestors but have lost their original purpose over time.
How are vestigial structure an example of evidence evolution?
Vestigial structures are remnants of features that were functional in the ancestors of a given species but are no longer useful in the current species. This supports the idea of evolution as it suggests that species have evolved over time from ancestors with different anatomical features. The presence of vestigial structures provides evidence of common ancestry and the gradual changes that have occurred over time through the process of evolution.
How are vegistigal structures an example of evolution?
Vestigial structures are remnants of organs or traits that were functional in ancestral species but are reduced or non-functional in present-day organisms. These structures provide evidence of evolution because they suggest that organisms have evolved from ancestors with different adaptations, and over time, structures that are no longer useful have become reduced or lost. This supports the idea that organisms have changed over time to adapt to their environment through the process of evolution.
What is the term for a structure that has no use in an organisms?
