Types of Fossils
A fossil consisting of all or part of the original organism. An example would be T. rex teeth found in a fossil graveyard.
What is original material?
The preserved remains of plants and animals.
What are fossils?
This rock dating method is a type of absolute dating that can only be used for "young fossils."
What is carbon-14 dating?
Structures in different organisms that appear similar
What are homologous structures?
The idea that organisms with the best traits will survive and reproduce.
What is survival of the fittest?
Fossil formed when an organism decays and leaves behind an empty space, which may then be filled in with sediment that hardens, creating a copy of the organism.
What is a mold and cast?
Preserved plants and animal fossils that are nearly identical to those we see today.
What are living fossils?
Rock layers are compared to other rock layers near them. The oldest rocks in a layered column or rocks must be those at the bottom of the column.
What is relative dating?
What are vestigial structures?
The idea that Earth's physical processes operate at the same rate in the present as in the past.
What is uniformitarianism?
An organism is buried by wet sediment and the organism's tissue is slowly replaced by an exact copy made of stone.
What is a mineralized fossil?
Each point where evolutionary family tree branches connect represents this.
What is a common ancestor?
This is found in fossils considered to be millions of years old, showing that they are actually much younger.
What is carbon-14?
Evolutionists believe that similarities in these are evidence of a common ancestor.
What are embryos?
The idea that species do not change over time.
What is the fixity of species?
Evidence that an organism leaves behind that is not part of the organism itself.
What is a trace fossil?
Different groups of organisms that God created to be distinct from each other.
What are kinds?
This type of dating relies on the known rates of radioactive decay of certain elements found in igneous rocks. It is common for this type of dating to yield ages that are known to be incorrect.
What is absolute dating?
True or False - The DNA of one kind of organism can change into the DNA of another kind.
What is false?
The blending of Darwin's theories of natural selection with mutations and genetics.
What is modern synthesis?
Formed when buried organisms decay, leaving behind only a thin film of carbon, like a printed image of the organism.
What is a carbonized fossil?
Many fossilized animals show strong evidence for having died by this.
What is drowning?
The assumed age for a fossil found above an igneous rock layer that is dated at 50 million years.
What is younger than 50 million years?
According to creationists, mutations are evidence of increasing disorder as a result of this.
What is the fall?
The idea that organisms can gain new traits and pass on those traits to their offspring.
What is the theory of acquired characteristics?
