All about fossils
All the fossils discovered and what we've learned from them.
What is the fossil record?
These can have a harmful effect on an organism.
What is a mutation?
The structure of an organisms body.
What is anatomy?
Ability for an organism to survive and reproduce.
What is fitness?
An example of this fossil is a footprint.
What is a trace fossil?
These are created by mutations.
What is an allele or gene?
Process by which two species evolve in response to changes over time.
What is coevolution?
Natural selection that act's on an organisms ability to get the best possible mate.
What is sexual selection?
A replica of an organism (like a shell, bone, or leaf) that forms when minerals or sediment fill in the hollow space left by the original organic material.
What is a mold?
Mutations are necessary for this process to occur.
What is evolution?
The shared use of DNA is one piece of evidence that every organism on Earth has one of these.
What is a common ancestor?
When a species no longer exist and will no longer be seen on Earth.
What is extinct or extinction?
Mutations occur in this structure.
What is DNA?
Similar structures that related species inherit from a common ancestor.
What are homologous structures?
Wearing away of Earth's surface by natural processes like wind and water.
What is erosion?
A replica of an organism (like a shell, bone, or leaf) that forms when minerals or sediment fill in the hollow space left by the original organic material.
What is a cast fossil?
Mutations create all the variations among members of a species and account for this among organisms on Earth.
What is genetic diversity?
One organism actually moves inside the other organism’s cell.
What is endosymbiosis?
Individuals with new alleles move from one population to another.
What is gene flow?
