How are fossils used?
Fossils are used by scientists to answer questions about species and maybe even dinosaurs. They use the fossils and run tests by using there DNA and seeing their molecular structure and running it by other animals for similarity's.
The term for dating fossils based on the relative positions of different rock layers is?
Ether the principle of superposition(also called the law of superposition- concept that the layer of sediment that is deepest is the oldest) or stratigraphy which is the study of layers, when using knowledge of when certain species existed and remains of those species while also studying the layers it is called biostratigraphy.
What kind of habitat that is most likely to be rich in fossils?
According to experts, the best environments to search for fossils are places near rocks or deserts. Most fossils are preserved in these areas.
What part of the body is likely to be much more diverse in mammal fossils compared to those of other groups?
Soft tissue.
Is stratigraphic dating accurate for dating fossils?
Carbon dating and radioactive dating are more effective, assuming those arn't the same thing. =]
What two observations made by Charles Darwin during his 5-year voyage that led him to conclude that living species evolved from extinct species?
One observation that Darwin made was the fossilized armadillos and these fossils closely resemble, but were not identical to, the armadillos living in the area. Another observation he made was the fact that the plants and animals of the Galápagos Islands resembled those of the nearby coast of South America.
What can embryos tell us about evolution?
Actually yes it can. Embryos, DNA sequences, and fossils amongst others things can help show similarities within species. This can show that those species have similar traits because they evolved from a common ancestor. But those differences show why they are different species and thus evolving.

How do scientists know that KT extinction took place?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
What country is the red rose from?
The species and wild roses originated on the continents of North America, Europe, and Asia. Rose fossils have been found in all of those areas.
What are 3 ways to determine the phylogenetic relationship among species?
DNA analysis is commonly used to determine the similarity between two species. From this, we can infer the evolutionary relationship of those species.

How those fossils affect people?
Poison
What fossils are helpful to geologist because they reveal the relative ages of the rock layers in which they occur?
Those types of fossils are called index fossils.
The remains of a once living thing?
Fossils are the remains of plants and animals that have been turned to stone.
What evidence is presented to support the theory that Pangaea actually existed?
Well, the main answer to this question are the fossils. Since fossils were found in different parts of the world and those fossils are of the same breed or species. Because having the same species in different locations are quite... Unusual, Alfred Wegener developed this theory. Searching for other evidences to prove his theory, he found that pieces of land from another place to another fit's perfectly like a piece of puzzle. This is the second answer to this question.
The oldest vertebrate fossils are those of ------- with no jaws?
fish
