What organism has a better chance of leaving a fossil?
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.
Which type of organism is most likely to be preserved?
Animals with hard parts are more likely to be preserved than animals that have soft bodies. Aquatic animals are more likely to be preserved than terrestrial animals because water ecosystems have greater preservation potential.
Which organism has a better chance of leaving a fossil behind after it dies earthworm or a fish explain your answer 2 points?
Explanation: a fish would have a better chance in making a fossil behind because it has a skeleton as a earthworm doesn’t have a skeleton.
Which kinds of organisms are more likely to be abundant in the fossil record?
The hard shell of a clam is more likely to fossilize because it is more resistant to biological and environmental destruction. For this reason, teeth, bones and other hard parts of organisms are much more numerous in the fossil record than soft tissues.
What evidence does the fossil record provide?
The Fossil Record Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. Scientists date and categorize fossils to determine when the organisms lived relative to each other.
What Cannot be determined from the fossil record?
The fossil record cannot accurately determine when one species becomes another species. However, two hypotheses regarding speciation also exist. Phyletic speciation suggests that abrupt mutations in a few regulatory genes occur after a species has existed for a long period of time.
What are 3 important limitations of the fossil record?
The fossil records suffer from 3 types of bias: temporal bias, geographic bias and taxonomic bias. Fossil of certain geologic time may be easier to find as compared to those or other era, such as newer fossils are easier to find than older ones.
What statement is best supported by fossil records?
Answer: Many organisms that lived in the past are now extinct .
What can fossils tell us about the past quizlet?
What do fossils tell us? Fossils give clues about organisms that lived long ago. They help to show that evolution has occurred.
What is the most recent fossil?
Chilean paleontologists announced Monday the discovery of a new species of giant dinosaurs called Arackar licanantay. The dinosaur belongs to the titanosaur dinosaur family tree but is unique in the world due to features on its dorsal vertebrae.
