Is fossil evidence used for the Theory of Evolution?
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.
State the difference between geological evolution and organic evolution?
The word evolution has grown to be rather over-used and sometimes even misused, and is commonly used to refer to non-biological systems when talking about them in a sense of their changes over a period of time. For example, while computer systems do not evolve in the way biological organisms do, they have changed drastically over the years through a series of smaller changes. Outwardly this system appears very similar to biological evolution, and so evolution phraseology is useful in this context. Geologic evolution refers to a system of changes within a geological system. An example would be studying how a specific area has changed from ocean to mountains to desert over a period of time. Once again, geological systems do no progress in a "natural selection" sense such as true evolution, but they can change in drastic ways via a series of smaller changes over a very long period of time. Organic evolution presumably refers to a system of changes within a biological range. This could refer to the evolution of species or traits within a species, or may even relate to pre-biogenesis evolution of basic amino-acid strands.
What is a fossil that can be used as a marker in time called?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
Why are fossils used as an evidence of evolution?
They are important because it helps scientists know what things looked like, what they ate, and to see if there are changes between what a certain species used to look like and what it looks like now. This helps scientists to make guesses about how animals or plants developed and changed over time.
Why are fossils of intermediate life forms likely to be rare if the pattern of punctuated equilibrium explains how evolution occurs?
Intermediate species forms, yes. A the taxa level, no. Still, not all taxa evidence is supportive of punctuation and stasis. Punctuated equilibrium is only one explanation of how evolution occurs in some species, not all species. The little shellies evidence gradualist processes very well.
How do fossils that formed in different rock layers provide evidence-of evolution?
Fossils' existence confirms that species are not fixed but can evolve into other species over time
How do fossils that form in different rock layers provide evidence of evolution?

How do fossils give proof of evolution?
Fossils show clear evidence that the earliest human species had many apelike features & have evolved over the years.
What are used as evidence for evolution?
Fossils. These show the incredible amount of time required to turn early life forms into stone. Studying the fossils, one can see the similarities and evolution of species over time. UNREST.

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.
How do fossils help explain the theories of evolution?
Fossils give us a lot of information about species which used to exist on Earth but which are now extinct. With this information we can see in greater detail how species have evolved over time.
5 of Charles Darwin's accomplishments?

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
Why are more recently deposited rock layers more likely to contain fossils resemble existing species than older rock layers?
The more recent rock layers will contain fossils that are more similar to current species because of evolution. The older the fossils, the more evolutionary changes will exist between them and current species which accounts for the greater differences.
How do fossil records back up evolution?
Fossil records back up evolution by showing the ancestors of extant species. If species didn't evolve, the fossils would be of species currently living, since none of them would have changed. Extant = Currently living Extinct = No longer living
