Survival of the Fittest
Extinction
100
A trait that helps an organism to survive and reproduce.
What is adaptation
100
This explains how a species can adapt and survive a change in its habitat.
What is evolution
100
Comparative anatomy is used by scientists to discover similarities in
What is species
100
This is a well tested concept that explains a wide range of observations.
What is scientific theory
100
This is the disappearance of all members of a species from earth.
What is extinction
200
This is how a species might survive in a new environment.
What is adaptation
200
This hypothesis proposes that evolution occurs slowly but steadily.
What is gradualism
200
These types of organisms have a backbone.
What are vertebrates
200
This gives the most reliable evidence of evolutionary relationships among species.
What is DNA
200
This diagram shows how different groups of organisms are related.
What is a branching tree diagram.
300
This is necessary for a species to adapt and survive.
What is genetic variation
300
This is the main cause of extinction
What is climate change
300
This is the study of the comparison of an organisms structure.
What is comparative anatomy
300
The specific environment that provides for an organisms needs.
What is habitat
300
A species will not become extinct if it can survive and
What is reproduce
400
These types of organisms have a nucleus.
What are eukaryotes
400
This is the preserved remains of an organism that lived in the past.
What is a fossil
400
Do robins have more in common with lions or owls.
What are owls.
400
This theory suggests that organisms which are able to adapt to an environment will survive extinction.
What is Survival of the Fittest
400
This states that characteristics that appear lower on a branch tree probably developed before characteristics higher on the tree.
What is the order of characteristics
500
This is a permanent change in DNA.
What is a mutation
500
This animal evolved to be able to withstand the harsh conditions of the ice age.
What is the woolly mammoth
500
This is a homologous structure, such as a backbone, that is shared with all organisms in a group.
What is a shared derived characteristic
500
This explains why tortoises and finches on the Galapagos Islands were different from one island to the next.
What is adaptation
500
Raccoons, lesser pandas, giant pandas, and bears are related through this.
What is a common ancestor
