Very few fossils of jellyfish or their close relatives have been found. This makes it hard to trace the evolutionary history of jellyfish using the fossil record. What explains this? (1 point)
Jellyfish fossils are buried deep under the ocean floor, not in land areas where scientists hunt for fossils.
Jellyfish have soft bodies that decay completely before fossilization can occur.
Jellyfish are a relatively new species in the history of living things on Earth and do not have ancient ancestors.
Jellyfish fossils are likely more fragile than other types of fossils and so they degrade before they can be examined.
I'll be glad to check your answer.
Think about what fossils are made of.
I think is B but I am not sure...thanks for help
B is correct.
thanks
You're welcome.
The correct answer is:
Jellyfish have soft bodies that decay completely before fossilization can occur.
This is because jellyfish have soft bodies without hard shells or skeletons, which makes it difficult for them to leave behind fossilized remains. Fossilization typically occurs when the hard parts of an organism, such as bones or shells, are preserved in sediment and undergo mineralization over time. However, the soft tissues of jellyfish do not usually have the necessary characteristics for preservation and are more likely to decay rapidly after death. Therefore, very few fossilized remains of jellyfish or their close relatives have been found, making it challenging to trace their evolutionary history using the fossil record.
