Structures, found in human arms, bat wings, and dolphin flippers, provide evidence of a common ancestor.
What are homologous structures?
This is what a cladogram tells us.
What is how closely organism are related to each other?
Organisms that only have a small number of DNA differences.
What is closely related?
Several sets of dinosaur tracks going in the same direction.
What is a herd of dinosaurs migrating?
This scientific theory explains how all living organisms are related through descent from a common ancestor.
What is the theory of evolution?
Structures, such as the wings of birds and butterflies, that have a similar function but do not share a common ancestry.
What are analogous structures?
The organism that is most closely related to the porpoise. (Dolphin, Orca or Beluga whale)
What is the Beluga whale?
A larger number of DNA differences would mean this.
What is more distantly related?

What is these organisms had a common ancestor?
Preserved remains or traces of ancient organisms provide evidence for common ancestry.
What are fossils?
These are structures that no longer have a use, but are left over from an evolutionary ancestor.
What are vestigial structures?
The feature humans, hares, caimans, and parrots share that the other three lineages did not inherit?
What is amniotic egg?
According to this DNA chart, the closest relative to the Peccary.
What is the pig?

What is evidence that dinosaurs were fighting when they died.
Fossils that show characteristics in between different groups of organisms and provide evidence for common ancestry.
What are transitional or intermediate fossils/forms?
The picture shows evidence of this.


What is common ancestry?
The crocodile is more closely related to the frog than the monkey.

What is false?
Of these animals, the species that it LEAST closely related to the deer.
What is the peccary?
Explain the law of superposition.
In undisturbed rock layers, the oldest rocks are found at the bottom, and the youngest rocks are found at the top.
This is the difference between relative dating and absolute dating of fossils?
What is relative dating determines the relative order of events or objects in geologic time, while absolute dating determines the precise age of a geological sample in years.
What the missing organism would look like.

Answers may very, but something like this:
OR
The trait that Pokemons have if they have a tail, but not fire.

What is a shell?
The number of base pairs in the human genome.
What is 3 billion?

What is trilobites curling up for protection?
The group of primates that includes humans, gorillas, and chimpanzees.
What are hominids?
