Which of the following is NOT evidence supporting evolution?
- A.
Comparative Anatomy
- B.
Comparative Homology
- C.
Comparative Embryology
- D.
Comparative Biochemsitry
- E.
Fossil Evidence
Correct Answer
B. Comparative HomologyExplanation
Comparative homology is actually evidence supporting evolution. Homology refers to the similarity in structures or genes between different species that suggest a common ancestry. By comparing the homologous structures or genes, scientists can trace the evolutionary relationships between species. Therefore, comparative homology provides evidence for the theory of evolution.Rate this question:

What is the name of the principle that states, "More recently deposted strata are on top of older strata of sedimentary rock"?
- A.
Principle of Lithification
- B.
Principle of Layerification
- C.
Principle of Sedimentaration
- D.
Principle of Superposition
- E.
Principle of Lathification
Correct Answer
D. Principle of SuperpositionExplanation
The principle of superposition states that in an undisturbed sequence of sedimentary rocks, the youngest rocks are found on top, while the oldest rocks are found at the bottom. This principle is based on the observation that sedimentary rocks are deposited in horizontal layers over time, with each new layer being added on top of the previous layers. Therefore, the correct answer is Principle of Superposition.Rate this question:

Which of the following is NOT a principle of natural selection?
- A.
The more advantages you have, the more likely you will survive/reproduce
- B.
More individuals are born than can survive
- C.
There are inherited variations in the population
- D.
Individuals with variations that give them an advantage are more likely to survive and reproduce
- E.
More individuals in the next generation will have the advantageous genes and trait
Correct Answer
A. The more advantages you have, the more likely you will survive/reproduceExplanation
The statement "The more advantages you have, the more likely you will survive/reproduce" is not a principle of natural selection. Natural selection is based on the idea that individuals with variations that give them an advantage are more likely to survive and reproduce, leading to more individuals in the next generation having the advantageous genes and traits. The other options listed in the question are all principles of natural selection, including the fact that more individuals are born than can survive and that there are inherited variations in the population.Rate this question:

In this type of natural selection graph, the weak are eleimated/less suited to their environment, and the graph moves in one direction.
- A.
Directional Selection
- B.
Stabilizing Selection
- C.
Disruptive Selection
Correct Answer
A. Directional SelectionExplanation
Directional selection occurs when individuals with extreme traits are favored over individuals with intermediate traits, causing the average phenotype of the population to shift in one direction. This can happen when there is a change in the environment or when a new predator or competitor is introduced. In this type of natural selection, the weaker individuals or those less suited to the environment are eliminated, leading to a shift in the graph towards the favored extreme trait.Rate this question:

Two gene pools are located in different areas of the globe. This would be an example of...
- A.
Divergent Evolution
- B.
Geographic Evolution
- C.
Reproductive Evolution
Correct Answer
B. Geographic EvolutionExplanation
Geographic Evolution refers to the process of speciation that occurs due to physical barriers, such as mountains or oceans, separating gene pools. In this scenario, the two gene pools are located in different areas of the globe, indicating that they are isolated from each other by geographical barriers. Over time, the populations in each gene pool will accumulate different genetic variations, leading to the development of distinct species. Therefore, Geographic Evolution is the most suitable explanation for this situation.Rate this question:

Coevolution is....
- A.
When two populations grow in the same area
- B.
When one population is wiped out by another population
- C.
When two populations mimic their evolutionary patterns
- D.
When one population grows in response to the other
Correct Answer
D. When one population grows in response to the otherExplanation
Coevolution is when one population grows in response to the other. This means that the growth of one population is directly influenced by the growth or changes in the other population. It is a reciprocal evolutionary process where the interactions between the two populations drive their evolutionary patterns. This can include situations where one population evolves specific traits or behaviors in response to the presence or actions of another population, leading to a coevolutionary relationship between the two.Rate this question:

When extinction occurs and there is a period of rapid speciazation, this is called...
- A.
Speciazation
- B.
Adaptive Radiation
- C.
Covergent Evolution
- D.
Punctuated Equilibrium
- E.
Inferring Phylogeny
Correct Answer
B. Adaptive RadiationExplanation
Adaptive radiation is the correct answer because it refers to the phenomenon where a single ancestral species rapidly diversifies into a variety of different species, filling different ecological niches. This typically occurs after a period of extinction, where many existing species have gone extinct, creating new opportunities for the surviving species to evolve and occupy new habitats. This process leads to the formation of multiple new species, each adapted to a specific environment or lifestyle.Rate this question:

What is taxonomy?
- A.
The science of evolution
- B.
The science of speciazation
- C.
The science of classification
- D.
The science of fossil recording
Correct Answer
C. The science of classificationExplanation
Taxonomy is the science of classification, which involves organizing and categorizing organisms based on their characteristics and relationships. It helps in identifying and naming species, as well as understanding their evolutionary history and relationships. By studying taxonomy, scientists can classify and group organisms into hierarchical categories, such as kingdoms, phyla, classes, orders, families, genera, and species. This systematic approach allows for better organization and understanding of the vast diversity of life on Earth.Rate this question:

What do taxonomists do?
- A.
They group together species into genus based homologies based on evidence from the fossil record
- B.
They classify a bunch of living things and divide them into kingdoms based on their differences
- C.
They group together species based on their similiarities and differences
- D.
They group together living things based on their characteristics and past phylogeny
Correct Answer
A. They group together species into genus based homologies based on evidence from the fossil recordExplanation
Taxonomists group together species into genus based on homologies, which are similarities in characteristics due to common ancestry. They use evidence from the fossil record to determine these similarities and group species accordingly. This helps in organizing and categorizing living things based on their evolutionary relationships and shared characteristics.Rate this question:

What does a phylogentic tree show?
- A.
The link between one organism to the next
- B.
The history of several populations, and which population evolved from what
- C.
A comparison of relationships between many populations
- D.
Evolutionary relationships based on a variety of types of evidence
Correct Answer
D. Evolutionary relationships based on a variety of types of evidenceExplanation
A phylogenetic tree shows the evolutionary relationships between different populations or species based on various types of evidence. It represents the history of how populations have evolved and how they are related to each other. By analyzing the similarities and differences in genetic, anatomical, or other characteristics, scientists can construct a phylogenetic tree to understand the evolutionary history and relationships among organisms.Rate this question:

In order for the earliest life forms to evolve, what must been there first?
- A.
Prokaryotic Cells - they couldn't use respiration at all, formed ER and nuclear envelope, had to eat aerobic heterotrophs to evolve
- B.
Prokaryotic Cells - they couldn't use respiration without oxygen, formed ER and nuclear envelope, had to eat aerobic heterotrophs to evolve
- C.
Eukaryotic Cells - used mitochondria and chloroplast to make oxygen, thus give the cells oxygen to use aerobic respiration
- D.
Eukaryotic Cells - came before prokaryotic cells, first made oxygen using ER and nuclear envelope, then ate aerobic heterotrophs which made prokaryotic cells
Correct Answer
B. Prokaryotic Cells - they couldn't use respiration without oxygen, formed ER and nuclear envelope, had to eat aerobic heterotrophs to evolveExplanation
Prokaryotic cells had to be present first in order for the earliest life forms to evolve because they couldn't use respiration without oxygen. These cells formed the endoplasmic reticulum (ER) and nuclear envelope, and they had to consume aerobic heterotrophs in order to evolve. This suggests that the ability to use respiration and obtain energy from aerobic sources was a crucial step in the evolution of life forms.Rate this question:

Vestingial structures had no....
- A.
Tail
- B.
Homologous structures
- C.
Backbone
- D.
Arms
Correct Answer
C. BackboneExplanation
Vestigial structures are remnants of organs or structures that were functional in ancestral species but have lost their original function in the course of evolution. The term "vestigial" implies that these structures have reduced or no function in the present organism. In the given options, the only structure that can be considered vestigial is the "Backbone" because it is not completely absent in humans but has lost its original function of providing support and protection to the spinal cord. The other options, such as "Tail," "Homologous structures," and "Arms," are not vestigial structures as they serve important functions in various organisms.Rate this question:
