This is the process of one species splitting into two or more species.
What is Speciation?
A population of Squirtles often gets beaten in battles due to a thinner shell. This is what will happen to Squirtle's shells over time.
What is get thicker?
This is what the word Fertile refers to.
What is able to produce offspring?
This barrier occurs when the sperm of species is unable to fertilize the eggs of another species.
What is Gametic Isolation?
This barrier occurs when genes of the different parent species may impair the hybrid's development or survival.
What is Reduced Hybrid Viability?
The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities?
A) The wing and front limb are homologous structures; Each evolved from a common ancestor
B) The wing and front limb are analogous structures; Each evolved from a common ancestor
C) The wing and front limb are homologous structures; Each evolved independently
D) The wing and front limb are homologous structures; Each evolved from the other

How many derived characteristics are shown on this Cladogram?
FIVE!
These are structures that are lost or reduced in organisms over time.
What are Vestigial Structures?
Charizards with large tail flames are thought to be stronger in battles so many trainers attempt to catch them. This is what will happen to the size of tail flames in the wild over many generations.
What is they will decrease?
This is what the word Viable refers to.
Living/strong offspring
This barrier occurs when two species rarely or never encounter each other due to differing habitats.
What is Habitat Isolation?
This is an example of a hybrid organism.
What is a Mule, Tiger Muskie, Liger, Saugeye, etc.?
The Galapagos Finch species are an excellent example of:
A) Selection on single-gene traits
B) Speciation
C) Stabilizing selection
D) Genetic equilibrium

Which two individuals are LEAST related?
What are Leopard Frogs and Humans/Chimps?
This is the term for a process in which individuals with favorable traits are more likely to survive and reproduce.
What is Natural Selection?
Trainers have found that if you breed Pikachu's with larger red cheek spots, they become more powerful. What is this breeding known as?
What is Artificial Selection?
The existence of barriers that impede members of two species from producing viable, fertile offspring.
What is Reproductive Isolation?
This barrier occurs when two species exhibit different courtship rituals.
What is Behavioral Isolation?
These are organisms that are produced by two species but are usually infertile or not viable.
What is a Hybrid?
The two main sources of genetic variation are:
A) Genotypes and phenotypes
B) Gene recombination and mutations
C) Single-gene traits and polygenic traits
D) Directional selection and disruptive selection

Identify the Sister Taxa on the Phylogenetic Tree below.
Primates and Rodents/Rabbits -and- Crocodiles and Dinosaurs/Birds
This is the name for two structures that look similar but have different functions.
What is Homology or Homologous Structures?
A population of bulbasaurs feeds on the fruits with relatively shallow seed depths. A new species of plant with a deeper seed depth begins to take over available land. This is what happens to Bulbasaur's teeth over time.
What is they will get longer?
These are barriers that impede organisms from mating that occur before fertilization.
What are Prezygotic Barriers?
This barrier occurs when two species breed during different times of day, seasons, or years.
What is Temporal Isolation?
This barrier occurs when hybrids are viable but sterile.
What is Reduced Hybrid Fertility?
Which animals on the cladogram pictured below are Warm-Blooded?
Horses, Dogs and Cats
This is the name for two structures that look different but have similar functions.
What are Analogous Traits or Analogy?
A population of Eevee's have grown up in a very warm environment, causing them to "evolve" into Flareon's. A flood occurred in that area causing them to change into Vaporeon's.
Identify the selective pressure.
What is the environment: The Water
These are barriers that occur after fertilization and stop offspring from being fertile or viable.
What are Postzygotic Barriers?
This barrier occurs when two species have different morphological components.
What is Mechanical Isolation?
This barrier occurs when the first generation hybrids are fertile, but the resulting offspring from those individuals are feeble or sterile.
What is Hybrid Breakdown?
Which two organisms are LEAST related?
Ambystoma mexicanum and Testudo hermanni
