How do fossils provide evidence about Evolution?

Rocks Contain Evidence of a Worldwide Deluge

Rocks contain important evidence about the origin of the earth. Geologists classify rocks into three basic types based upon the processes by which the rocks are formed. The first type isigneous rock, which is formed from magma. If magma reaches the earth's surface, it changes into the lava that spills from volcanoes. Once the rocks hit the surface, they are subject to environmental factors such as wind, rain, and even catastrophic events (like a worldwide Flood).

These factors will cause rock to fracture into small pieces that become cemented together. Cement is made up of chemicals that, when mixed with water, harden in a short period of time. Rocks are made up of small fractures or sediments are classified as sedimentary. The third type of rock is metamorphic-rock that has changed dramatically into a new chemical composition. For instance, limestone changes into marble when placed under tremendous heat and pressure.

A set of basic questions arises when one considers the processes required to form these three kinds of rock. The answers offered by the evolutionary model leave gaping holes in the search for intelligent conclusions. The catastrophic worldwide Flood model offers a more rational, coherent framework for answering these basic questions.

1. How do the sedimentary rocks get hard?

Sedimentary rock needs water for cementing the tiny particles of sediments together. Where did the water come from? Evolutionists resolve this dilemma by waving the magic wand of "time." They insist that the sediments are washed into rivers, lakes, and oceans, and then fall to the bottom and pile up in layers. After many years, these sediments harden in layers, with those on the bottom hardening first. The problem with this theory is that there are beds of sedimentary rock everywhere on top of the earth's crust. Most of the large mountain chains are made of sedimentary rocks. How did all those sediments collect and become cemented together to make towering mountains? The logical answer is a worldwide Flood.

2. Is there an alternative to time as the mechanism of rock formation?

Yes! Rock formation can be explained by means of two processes, compaction and cementation that could have occurred within one year after the waters of the Flood began to subside.

Global Floodwater would have collected a huge amount of sediment. When the Floodwater came to rest, the sediment would have begun to fall out. At the beginning, before the water started to evaporate, there would have been a great deal of pressure on the bottom layers. This would cause compaction. Creation Geologist John Morris explains this as a pancake effect.

"When a pancake layer of sediments is covered with other pancakes, the sand grains are pushed closer together; squeezing the water out. Compaction is the first step in turning sediment into a sedimentary rock, but not the only step." John Morris, The Geology Book,(Master Books, Green Forrest,AR.2000) p36.

The second step is cementation. The glue that hardens the rock is generated by the warm water and minerals produced by the effects of the Flood. It does not take a long time for the rock to harden into layers. The layers that are observed are actually strata of sediments called, as John Morris put it, "pancakes."

This process need not take a long time. Remember, making sedimentary rocks is like preparing cement. To make cement you need to have the proper ingredients and the right conditions. The waters would have been warm and deep at one time, giving the added energy needed for compaction. The worldwide Flood model provides the massive amount of water and sediment that would be needed to build the thick pancake layering for the mountains present today. It makes for a more intelligent alternative.

3. What supplied the massive pressure and heat needed to make metamorphic rocks?

The heat and pressure required to make the vast amount of metamorphic rock in the earth's crust is not today available. The source of energy to do that has to be tremendous and is not presently observed anywhere on earth. A catastrophic Flood that is spoken of in Genesis 6-9 could produce the forces needed to create metamorphic rock on the scale observed today.

4. Why are fossils found in abundance on every continent?

Fossils are traces of plant and animal life that existed in the past and are found only in sedimentary rocks. Creationists believe that fossils were deposited during the global Flood, an obvious source of the water needed for both compaction and cementation. Fossils number in the trillions and suggest a swift catastrophic event that buried them before any decay or decomposition occurred. Rocks at one time had to be soft or have a liquid to flow over them and bury them. Castings of thousands of fish have been found in sedimentary layers. If these fish had lain on the ground exposed to the elements they would have disintegrated rapidly. Fish bones and scales do not harden…they scatter. Yet there are fossilized castings that show bone, and even scale, as if somebody took a picture and embedded it in the rocks. Fish fossils, for example, are common in the Green River Shales in Wyoming. One would have to conclude that these fossils, as observed today had to be the result of a catastrophic event that would cause rapid burial. The fossil evidence points to a worldwide Flood.

Is a piece of pottery an example of a fossil why or wht not?

Pottery is not a fossil. It is an antiquity or historical artifact.

What factors make it more likely that an animal will be preserved as a fossil?

There are many factors that make it more likely that an animal will be preserved as a fossil. One factor is living in a swampy area.

Yes, fossils are the traces and remains of organisms and plants that were buried and maintained under pressure

What is the derivation of the word fossil?

From the perfect passive participle of the Latin verb fodere, to dig up.

fossus = having been dug up

How did dinosaurs turn into fosils?

+ "they became fossils because the bones turned into stone leaving them so we could find"

Fossilisation occurs only when creatures are rapidly buried. In the case of fossils they are found in sedimentary rock all over the surface of the Earth. This type of rock is formed by water where particles are broken down, sorted and deposited by the water. Most fossils (95%) are marine creatures such as shells and fish, with less than 1% being land creatures such as dinosaurs. Many fish fossils are found with skin in tact and some even found eating/swallowing other fish at the time they were rapidly buried. Dinosaurs are only found as fossilised bones. The skin etc is missing because during flooding the body has begun to decompose and when buried (fossilised) the bones were the only preseravable part remaining. Most fossils are marine creatures because during flooding, creatures closest to the sea bed will be buried first, whereas creatures higher up from the sea bed (land animals) are less likely to be buried in sediment and will instead decompose on the surface of the water.

See Pierre Julien and Guy Berthault sedimentation experiments 1986.

What evidence do fossils provide of the environments past and present?

changes in the environment e.g. the place, temperature, climate.

What is an example of a fossil in a rainforest?

Fossils are found in rocks not rain forests.

What are 2 ways in which fossils help us?

they show us what our ancestors did or if we've evolved and we looked different then, they show us what we had back then, sometimes what happened back then, we can see how old certain items are to see when it was used etc.

Why wouldn't a jellyfish form a fossil?

Jelly fish don't have bones or teeth which are typically what fossilizes. Jellyfish are mostly water so they decompose extremely easily. Its like trying to fossilize soggy jello. They live in open oceans so its difficult for a jellyfish to become fossilized when there isn't a whole lot of soil around.

What From earliest to most recent what is the correct order in which organisms appear in the fossil record?

What might you infer if you found fossils of tropical plants in a desert?

That the rock where you found the fossil was at some point in a place with tropical climate, but has somehow moved to the place with a colder climate. This is generally accepted as proof of, and explained by, plate tectonic theory.

Umm...you could also conclude "if you found a fossil of a tropical plant in a cold climate?" that you need to put your coat on before venturing outside again...it's cold. And that somebody is playing a trick on you and planted the fossil just to see if you would take that coat off forgetting you were in a cold climate.

What rock types would most likely contain fossil?

Sedimentary rock is the only type of rock that will contain fossils, but there are several types of sedimentary rock.

Examples:

Clastic Sedimentary Rocks (particles of silt and/or sand that cement together): Conglomerate, Breccia, Sandstone, Siltstone, Shale.

Examples:

Chemical Sedimentary Rocks (forms when mineral constituents become supersaturated and inorganically precipitate):

Evaporates:

Halite, Gypsum

Carbonates:

Limestone, Fossiliferous Limestone

Siliceous Rocks: Chert

Organic Sedimentary Rocks: Coal.

The rocks listed in BOLD will likely be found with fossils.

Where was the first human fossil found?

No one knows what the first fossil found was - humans have been collecting the oddly shaped stones for thousands of years around the world. It has only been in the last couple of centuries that fossils have been recognized as the remains of ancient and extinct animals.

What is the proof for macro evolution?

AnswerOkay, perhaps an answer from an evolutionary biologist will help (someone who actually understands evolution). Obviously, this answer will be a gross oversimplification. Microevolution and macroevolution are, essentially, the same thing. However they are very different in the respect that macroevolution extends over many generations and can eventually lead to another species. Yes, there is proof of macroevolution. Obviously we do not have the time to sit around and wait thousands or millions of years to watch it happen, so we must look elsewhere. Summation is a great example. Scientists from different fields (such as biology, paleontology, anatomy, genetics, microbiology, anthropology, etc.) can take different species of animals and arrange them on a phylogenetic tree (tree of life). Every time, from all different fields, independently, all of the trees of life will match...EXACTLY. We also have millions of fossils to show transitions and millions of animals to compare DNA.

Specifically regarding humans, Chromosome 2 proves that we do in fact share a common ancestor with the Great Apes. All of the Great Apes have 48 chromosomes (24 pairs), we have 46 chromosomes (23 pairs). Where did that pair go? We believed that a chromosome had gotten fused, but we weren't sure. If there was no fused chromosome, then evolution had a huge problem. Then we found Chromosome 2. Chromosomes have a telomere on each end and a centromere in the middle. Each chromosome has two telomeres and one centromere. So if a chromosome had been fused, it would have three telomeres (one on each end and one in the middle) and two centromeres (one should be inactive). Guess what...we found it. Chromosome 2 has three telomeres and two centromeres (unlike any other chromosome). Somewhere along the line, we broke off and took our own evolutionary route, although we still belong in the family of Great Apes.

On a side note, Endogenous Retroviruses (ERVs) exist in DNA. They are essentially viruses that are "good," and they exchange information. If they land on a body cell of an organism, their information is forever lost. However if they land on a sperm or an egg, their information will be passed to that organism's offspring. Chimpanzees and humans have over 60 ERVs in the exact same places in our genome. The chances of even one ERV landing in the same spot in our genomes (if we weren't related) is .00000000016% (since our genome is about 3 billion base pairs long). Think of the likelihood that over 60 ERVs would land in the exact same spots.

Things to study to improve your understanding:

- Summation

- Atavisms

- ERVs

- Vestigial Structures

- Pseudogenes (relates to atavisms)

- Speciation (very important)

- Allele Frequencies

- Genetic Drift

AnswerAlthough many examples are produced, when examined closely, they often could be interpreted differently under another paradigm. Some of the evolutionary arguments for vestigial organs and embryonic recapitulation have turned out to be either fallacious or fraudulent (in the case of the latter). Answer">Answer">AnswerYou believe in micro evolution do you not? If so then you must accept macro evolution as it is micro evolution on a grander scale AnswerThe evidence does not support it... case in point: antibacterial soap... the bacteria are microevolving, but the whole time, they remain bacteria. The DNA information is so specific, (according to Richard Dawkins, equal to 30 sets of the Encyclopedia Brittanica) and ordered in such a way, it has never been observed or proven to occur, in any single celled creature or multi-celled creature.

Why is the fossil record important for evolutionary theory?

Fossil records date back to the time when 1st life forms were found on this earth. Hence in order to know about the information of what happened there and many other queries, fossil records are a must.

Why are there no fossils of dragons?

No matter where you look, you won't find any fossils of our kind. We never allow that type of evidence to be discovered. Whenever any mortal one of our kind, good or evil, passes away, we use various processes to either relocate the carcass, or eliminate it's existence.

~Goldraid~

*PS: Please quit deleting my answers already, "Jponbac", they're fact, not fiction!

Dragons have never existed. Early man may have mistaken dinosaur bones and footprints for something like a dragon, but they made it up that they existed. If you want to see fossils go to a natural history museum for dinosaur bones. Dragons are in the same realm with unicorns and mermaids.

Dragons do exist but you cannot find their fossils.

Why can relative dating be used only to estimate the age of a fossil?

by comparing its placement with that of fossils in other layers of rock

What is the thick black liquid formed from the buried remains of microscopic marine organisms?

Crude oil comes from these remains but it takes a very long time for them to form.

What do scientists use to measure the absolute age of a rock?

Finding the age of rocks based on the presence of naturally occurring long-lived radioactive isotopes of several elements in certain minerals and rocks.

Many rocks and minerals contain radioactive atoms that decay spontaneously to form stable atoms of other elements. Under certain conditions these radiogenicdaughter atoms accumulate within the mineral crystals so that the ratio of the daughter atoms divided by the parent atoms increases with time. This ratio can be measured very accurately with a mass spectrometer, and is then used to calculate the age of the rock by means of an equation based on the law of radioactivity. The radioactive atoms used for dating rocks and minerals have very long half-lives, measured in billions of years. They occur in nature only because they decay very slowly. The pairs of parents and daughters used for dating are listed in the table.

(see also the related link)
The age of a rock may be determined by analysis of the matter it contains. Many minerals have radio active half lives that can be used to determine roughly how long ago the rock was formed. Another indication may be the type of fossils found in sedimentary rocks.
