This is the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations.

What is Natural Selection?

100
These are the three types of adaptations.
What are Structural, Behavioral, and Functional?
100
These are the two major variations of the peppered moth.
What are Light Moths with dark spots, and Dark Moths with light spots.
100
We studied three different types of evidence that supports evolution. These are any two of the three we studied.
What are Comparative Anatomy, Embryology, and/or Molecular Biology (DNA)?
100
This is an adaptation that enables a species to blend in with its environment.
What is Camouflage?
200

This is a slight difference in an inherited trait of individual members of a species.

What is Variation?

200
The long finger bones in a bat's hand that support the flaps of skin as they fly is an example of this type of adaptation.
What is a Structural Adaptation?
200
This variation in the Peppered Moth population was a benefit in the non-polluted forests.
What is the Light Moth with dark spots.
200
Which type of comparative anatomy tells us that two species are not closely related?
What are Analogous Structures?
200

These two types of Comparative Anatomy show that two species are closely related. 

What are Homologous Structures & Vestigial Structures. 

300

This is an inherited trait that increases an organism's chance of surviving and reproducing in its environment.

What is an Adaptation?

300
The nocturnal nature of the peppered moth is an example of this type of adaptation.
What is a Behavioral Adaptation?
300
This variation in the peppered moth population was a benefit once the forests became polluted.
What are Dark Moths with light spots?
300
What would it mean if two species have 97% of their DNA the same?
What is that they are closely related?
300
These are body parts of organisms that are similar in structure and position but different in function.
What are Homologous Structures?
400

This is the science of the development of embryos from fertilization to birth.

What is Embryology?

400
This type of adaptation changes the way that their body carries out internal processes.
What are Functional Adaptations?
400
This is how the population of peppered moths changed?
What is they went from mostly Light Moths with dark spots to mostly Dark Moths with light spots?
400
Every single species that has a backbone (vertebrates) has this structure when they are an embryo, and shows that they share a common ancestor.
What are pharyngeal pouches?
400
These are body parts that perform similar functions but differ in structure.
What are Analogous Structures?
500

This is the study of similarities and differences among structures of living species.

What is Comparative Anatomy?

500
Give an example of a Functional Adaptation.
Answers will vary...
500
Over long periods of time, variations are naturally selected to become adaptations. Once a group of organisms have lots of adaptations, we say that they have done this.
What is they Evolved?
500
Identify an example of a vestigial structure.
Answers will vary...
500
This is the breeding of organisms for desired characteristics.
What is Selective Breeding?
