Which of the following is NOT evidence supporting evolution?
Correct Answer
B. Comparative Homology
Explanation
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.
2.
What is the name of the principle that states, "More recently deposted strata are on top of older strata of sedimentary rock"?
Correct Answer
D. Principle of Superposition
Explanation
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.
3.
Which of the following is NOT a principle of natural selection?
Correct Answer
A. The more advantages you have, the more likely you will survive/reproduce
Explanation
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.
4.
In this type of natural selection graph, the weak are eleimated/less suited to their environment, and the graph moves in one direction.
Correct Answer
A. Directional Selection
Explanation
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.

Two gene pools are located in different areas of the globe. This would be an example of...
Correct Answer
B. GeograpHic Evolution
Explanation
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.
6.
Coevolution is....
Correct Answer
D. When one population grows in response to the other
Explanation
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.
7.
When extinction occurs and there is a period of rapid speciazation, this is called...
Correct Answer
B. Adaptive Radiation
Explanation
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.
8.
What is taxonomy?
Correct Answer
C. The science of classification
Explanation
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.
9.
What do taxonomists do?
Correct Answer
A. They group together species into genus based homologies based on evidence from the fossil record
Explanation
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.
10.
What does a phylogentic tree show?
Correct Answer
D. Evolutionary relationships based on a variety of types of evidence
Explanation
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.
11.
In order for the earliest life forms to evolve, what must been there first?
Correct Answer
B. Prokaryotic Cells - they couldn't use respiration without oxygen, formed ER and nuclear envelope, had to eat aerobic heterotropHs to evolve
Explanation
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.
12.
Vestingial structures had no....
Correct Answer
C. Backbone
Explanation
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.
