Occasionally. Fossils are rare, and most often only preserve hard parts such as shells and bones. Fossil invertebrates and even single celled organisms are known. A Russian group recently reported finding a fossil of two cells in sexual union.
On a side note, the preservation of fossils generally declines with age. Nearly intact DNA has been recovered from Neanderthal skeletons that are a few tens of thousands of years old and tissue residue containing highly degraded DNA was found inside a 70 million year old T-Rex bone. But no one has ever found even the slightest trace of DNA from a Trilobite, because the last of these died out some 250 million years ago.
What else can I help you with?
Where large fragments of DNA would be found?
If you mean in fossils or decomposed bodies, it would be best found in the teeth.
How do scientist learn about plants that are extinct?
Scientists can learn about extinct plants through fossils, pollen records, and ancient DNA analysis. Fossils provide direct physical evidence of past plant species, while pollen records give insights into the types of plants that existed based on the pollen grains preserved in sediments. Ancient DNA analysis can also reveal genetic information about extinct plants by extracting and sequencing DNA from preserved specimens, providing a deeper understanding of their evolutionary history.
What is so nice about fossils that have been encased in amber or ice?
Fossils encased in amber or ice are well-preserved, offering unique insights into ancient ecosystems and organisms. The amber fossils often capture minute details due to the clarity and protection provided by the resin. Ice fossils can include soft tissues and DNA that are usually not preserved in other types of fossils due to rapid freezing.
How the fossils can give us information about their specie?
Fossils can provide information about a species through their morphology, which includes features like size, shape, and structure. By comparing fossils to known species and studying their environment, scientists can make inferences about the behavior, diet, habitat, and evolutionary history of the organism. Additionally, isotopic analysis or DNA extraction from fossils can offer insights into the genetics and diet of the species.
What was the preserved remains of ancient organisms called?
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
How is DNA extracted from fossils what are the costs associated with testing DNA in fossils?
Fossils are the mineralised remains of organisms and contain no organic material.
Does fossils have DNA?
they do actually the fossel contains its animals DNA
What Most direct evidence of evolution relationship between animal species come from comparing what anatomy or weight or DNA of fossils?
DNA. fossils do not necessarily mean two animals are closley related
What are types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
How can you tell fossils are related?
because the scienctists will test it out, and usally they have the same DNA
Dinosaurs were created from dinosaurs DNA extracted from fossils?
fossils extracted from dinosaurs created from DNA extracted from dinosaurs?
What two types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
What are two types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
Are fossils examples of organic matter and why?
Yes, fossils are examples of organic matter because they are the preserved remains or traces of once-living organisms. Fossils can include bones, shells, teeth, and other organic materials that have undergone a process of mineralization or replacement with inorganic materials to become stone-like structures.
Can you bring back an animal back from its fossils?
Nope Unless you've successfully managed to clone living creatures, and you have plenty DNA to work with, bringing an animal from its fossils would be impossible.
Where large fragments of DNA would be found?
If you mean in fossils or decomposed bodies, it would be best found in the teeth.
What is the DNA structure of a brontosaurus?
We have no DNA from Brontosaurus, or any other dinosaur. DNA can last hundreds of thousands of years in permafrost, but no Brontosaurus fossils have been preserved constantly in permafrost. Additionally, Brontosaurus fossils are millions of years old, not hundreds of thousands, so even if it had been constantly frozen they probably would still have no DNA left. One last note: Brontosaurus is not a real dinosaur; you are referring to Apatosaurus.
