permineralized fossil
answer 2 Fossilized wood often contains sufficient detail to name the species.
Fossil pollen degrades very little, and is a branch of Geology, called Palynology.
Insects in amber are very well preserved. (Jurassic Park excepted!)
The original structures of an organism remain in its genetic code, specifically in its DNA. These structures dictate the organism's development and are passed down through generations. Additionally, certain physical structures of an organism, such as bones and tissues, can also remain unchanged over time.

What does a vestigial structure mean?
A vestigial structure is an anatomical feature that no longer serves a clear function in an organism, but is a remnant of a structure that was functional in its evolutionary ancestors. These structures are often reduced in size or complexity compared to the original functional structure.
Structures with no function that are remnants of an organisms evolutionary past are?
Vestigial structures are anatomical features that have lost their original function in the course of evolution. These structures are a result of changes in the organism's environment or behavior, rendering them unnecessary. Examples in humans include the appendix and wisdom teeth.
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.
Structures which are fully developed in one group of organism but reduced or possibly nonfunctional in a similar group are referred to as?
Structures which are fully developed in one group of organism but reduced or possibly nonfunctional in a similar group are referred to as vestigial structures. These structures are remnants of organs or features that served a purpose in the organism's ancestors but are no longer needed in the descendant species.
Do all cells have interior structures that perform specific functions for the organism?
Yes, these structures are called organelles and they are what defines a cell.
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.
What are the similarities between original replaced remain fossils and cast and mold fossils?
All are indicative of the size and shape and possible habitat of the original organism.
What are vestigial structures?
A structure that has no use in the organism
What do you call an organ that serves no useful function in an organism?
A vestigial organ. These are remnants of structures that had a purpose in ancestral species but have lost their original function in evolution.
What is a vestigal structure?
A vestigial structure is a physical characteristic of an organism that has lost its original function through the process of evolution. These structures are remnants of traits that were once useful to the organism's ancestors but are no longer needed in their present form. Examples include the human appendix and the wings of flightless birds.
What are body like structures that do not seem to have a function?
Seem is the operative word here. Vestigial structureshave another job from the original bob they did in the organism.
What does a vestigial structure mean?
A vestigial structure is an anatomical feature that no longer serves a clear function in an organism, but is a remnant of a structure that was functional in its evolutionary ancestors. These structures are often reduced in size or complexity compared to the original functional structure.

Vestigial structures are anatomical features that have lost their original function in the course of evolution. These structures are a result of changes in the organism's environment or behavior, rendering them unnecessary. Examples in humans include the appendix and wisdom teeth.
What type of asexual reproduction involves an organism starting to grow out of the parent organism and that may or may not remain attached to the parent organism?
Fragmentation is a type of asexual reproduction that involves an organism starting to grow out of the parent organism that may or may not remain attached to the parent organism.
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.
How are the parts of an organism arranged?
The parts of an organism are arranged in specific structures and systems that work together to support the organism's functions. These structures can be simple or complex, depending on the complexity of the organism. The arrangement of parts is crucial for the organism to carry out its life processes efficiently.
When a organism evolves does the original organism die off?
yes
