Natural vs Artificial Selection
Evidence of Natural Selection
The Fossil Record and Branching Trees
Homologous vs Analogous Structures
Adaptations and Variations
100
This is the process where organisms that are better adapted (suited) to their environment tend to survive and produce more offspring.
What is Natural Selection?
100
All of these are examples of evidence for natural selection except this one:
a. The fossil record
b. Embryos
c. Homologous Structures
d. Acquired (not inherited) traits
What are Acquired Traits?
100
Modern horses evolved from Eohippus. This is what happened to the size of horses as they evolved over time. 
They got bigger (they grew)
100
This word is used to describes organisms who have a similar bodily structure even though it might serve different functions in each species. (like flying for chickens and running for cats)
What is a homologous structure?
100
This is a physical or behavioral characteristic (a trait) of an organism that enhances its ability to survive and reproduce in its environment.
What is an Adaptation?
200
This is the process where humans choose and enhance specific traits in plants and animals, also known as selective breeding.
What is Artificial Selection?
200
This term refers to the study of how embryos develop from a single fertilized egg.
What is embryology?
200
Based on the image below: The trilobite is located at layer B. This layer or layers is/are older than layer B. (Which layer or layers is/are older than layer B?)
What is layer A?
200
This word is used to describes organisms who have a different bodily structure even though it might serve similar functions in each species. (like swimming in penguins and fish)
What is an analogous structure?
200
This is a word that describes organisms within a species that are not identical; some organisms have mutations.
What is variation?
300
This is a term equivalent to the term "Survival of the Fittest".
What is Natural Selection?
300
All organisms and species are made of the same DNA bases (Adenine A, Thymine T, Cytosine C, and Guanine G)
True or False
What is TRUE?
300
Fossils always show that species stayed the same over time. (true or false)
What is False?
300
Based on the diagram below, these two organisms have the most recent common ancestor.
Who are the cat and the human?
300
This word means an adaptation where an organism uses coloration, pattern, or shape to blend into its environment, making it difficult for other animals to detect or recognize it.
What is camouflage?
400
This is a word that describes where individuals in a population strive for limited resources like food, water, mates, or territory.
What is Competition?
400
This is a term that means that different species evolved from a single, earlier life form at some point in evolutionary history.
What is a common ancestor?
400
These two organisms are the LEAST related to each other based on the cladogram below.
What are cats and amphibians?
400
All of these organisms have a common ancestor with each other. (true or false)
What is True?
400
This is used to describe a population where more offspring are produced than can survive (similar to overpopulation)
What is overproduction?
500
The individuals with the most advantageous traits are more likely to do this.
What is survive and reproduce?
500
A branching tree diagram (cladogram) represents this.
What are Common ancestors?
What are related Organisms/species?
500
These traits are the traits that Marsupials and Dogs have in common, based on the cladogram below.
What is fur, amniotic egg, and four limbs?
500
The front limbs of a human, a bat, and a whale are an example of this type of structure.
A homologous structure
500
What is the name of the process where random changes in the DNA of an organism can lead to new traits that may benefit the species in survival?
What is a mutation?
