10th Grade Biology Evolution Questions and Answers
- 1.
There are times and places when all 3 things required to maintain genetic equilibrium exist and evolution doesn't happen.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
True Genetic equilibrium refers to a state where allele frequencies in a population remain constant over generations. However, evolution is the change in allele frequencies over time. Therefore, if all three conditions required for genetic equilibrium (no mutation, no migration, and no natural selection) are present, evolution would not occur.Rate this question:

Name 1 condition required to maintain genetic equilibrium under the Hardy-Weinberg Principle
Correct Answer
No net mutuations occur
individuals don't enter or exit the population
population is large
individuals mate randomly
selection does not occurExplanation
To maintain genetic equilibrium under the Hardy-Weinberg Principle, several conditions must be met. Firstly, there should be no net mutations occurring, meaning that there should be no changes in the genetic material of the population. Secondly, individuals should not enter or exit the population, ensuring that the gene pool remains constant. Additionally, the population should be large to prevent random genetic drift. Furthermore, individuals must mate randomly, without any preference or selection for certain traits. Lastly, selection should not occur, meaning that there should be no advantage or disadvantage for certain genotypes in terms of survival and reproduction.Rate this question:
- 3.
Traits that show stabalizing distribution and are determined by more than one gene are called
Correct Answer
polygenic inheritanceExplanation
Polygenic inheritance refers to the inheritance of traits that are controlled by multiple genes. In this type of inheritance, each gene contributes a small effect to the phenotype, resulting in a continuous distribution of traits. Stabilizing selection occurs when individuals with intermediate phenotypes have a higher fitness compared to those with extreme phenotypes. Therefore, traits that show a stabilizing distribution and are determined by more than one gene are called polygenic inheritance.Rate this question:
- 4.
___________ structures come from the same embryonic tissue.
Correct Answer
homologousExplanation
Homologous structures come from the same embryonic tissue. This means that they have similar anatomical structures, even though they may have different functions. These structures are evidence of common ancestry and evolution. For example, the forelimbs of different mammals, such as humans, dogs, and bats, have the same basic structure of bones, even though they are used for different purposes. This similarity indicates that these species share a common ancestor and have evolved from a common embryonic tissue.Rate this question:
- 5.
Breeding cows that give the most milk or the fastest horses is an example of
Correct Answer
artificial selectionExplanation
Breeding cows or horses to specifically enhance certain traits, such as milk production or speed, is known as artificial selection. This process involves humans selectively breeding animals with desired characteristics in order to create offspring with those same traits. Over time, this can lead to significant changes in the genetic makeup of a population, as certain traits become more prevalent. Artificial selection is a deliberate and controlled method used by humans to manipulate the genetic composition of a species for desired outcomes.Rate this question:

Darwin's idea that each living species has descended with changes from other species over time is called
Correct Answer
descent with modificationExplanation
Darwin's idea that each living species has descended with changes from other species over time is called "descent with modification." This concept suggests that species evolve through a process of gradual changes over long periods, with new traits being passed on to offspring. It is based on the understanding that organisms with advantageous traits are more likely to survive and reproduce, leading to the accumulation of beneficial modifications in subsequent generations. This theory revolutionized our understanding of the diversity of life on Earth and remains a fundamental principle in the field of biology.Rate this question:
- 8.
The ability of an organism to survive in its environment is called
Correct Answer
adaptationExplanation
Adaptation refers to the ability of an organism to adjust and survive in its environment. This process involves the organism developing certain traits or behaviors that allow it to better suit its surroundings and increase its chances of survival. These adaptations can include physical characteristics, such as camouflage or protective structures, as well as behavioral changes, like migration or hibernation. Through adaptation, organisms are able to thrive in various habitats and cope with changes in their environment over time.Rate this question:
- 9.
Lamark proposed that organisms could alter the size or shape of their bodies through use or disuse and pass these traits on to their offspring. this idea is called
Correct Answer
acquired characteristicsExplanation
Lamarck's proposal of acquired characteristics suggests that organisms can change the size or shape of their bodies through the use or disuse of certain traits, and these changes can be inherited by their offspring. This concept implies that traits acquired during an organism's lifetime can be passed down to future generations.Rate this question:
- 10.
Genetic Drift happens in populations that are
- A.
Small
- B.
Large
Correct Answer
A. SmallExplanation
Genetic drift occurs in small populations because there is a higher chance of random fluctuations in allele frequencies. In small populations, genetic variations can be lost more easily due to random events such as the death or reproduction of a few individuals. This can lead to a change in the gene pool over time, causing certain alleles to become more or less common. In contrast, in larger populations, the effect of random events is diluted, making genetic drift less significant.Rate this question:

Physical characteristics like walrus tusks and porcupine quills or behavioral characteristics like hibernating and living in herds are examples of inherited traits called ________ that help an organism to survive and reproduce in its environment.
Correct Answer
adaptationsExplanation
Physical characteristics like walrus tusks and porcupine quills or behavioral characteristics like hibernating and living in herds are examples of inherited traits called adaptations that help an organism survive and reproduce in its environment. Instincts are innate behaviors that are genetically determined and do not require learning or experience. These traits are passed down from generation to generation and are essential for the survival and reproductive success of an organism in its specific environment.Rate this question:
- 12.
In addition to observing living organisms, Darwin studied the preserved remains of ancient organisms called___________.
Correct Answer
fossilsExplanation
Darwin studied the preserved remains of ancient organisms called fossils in addition to observing living organisms. Fossils provide valuable evidence of past life forms and allow scientists to study the evolution and changes that have occurred over millions of years. By examining fossils, Darwin was able to gather insights into the history of life on Earth and develop his theory of evolution. Fossils provide a unique window into the past and help us understand the diversity and interconnectedness of living organisms.Rate this question:
- 13.
Name the islands where Darwin observed finches, iguanas, and turtles that led to his Theory of Evolution.
Correct Answer
GalapagosExplanation
Darwin observed finches, iguanas, and turtles on the islands of Galapagos, which led to his Theory of Evolution. The unique species found on the island, with distinct adaptations and characteristics, provided evidence for natural selection and the process of evolution. These observations played a crucial role in shaping Darwin's understanding of how species evolved over time.Rate this question:
- 14.
A well supported testable explanation of phenomena that have occurred in the natural world is called a
Correct Answer
theoryExplanation
A theory is a well-supported and testable explanation of phenomena that have occurred in the natural world. It is based on evidence and observations and provides a framework for understanding and predicting natural phenomena. Theories are developed through rigorous scientific research and experimentation, and they can be modified or refined as new evidence emerges. Theories are an essential part of scientific knowledge and help scientists make sense of the natural world.Rate this question:
- 15.
The process in which organisms that are better suited to their environment survive and reproduce is called
Correct Answer
survival of the fittestExplanation
Survival of the fittest refers to the natural process by which organisms that possess advantageous traits for their environment are more likely to survive and reproduce. These advantageous traits can include physical characteristics, behaviors, or adaptations that allow individuals to better compete for resources, avoid predators, or successfully reproduce. Over time, these advantageous traits become more common in the population, leading to the evolution of species that are better suited to their environment. This concept was coined by Charles Darwin and is a fundamental principle of evolutionary biology.Rate this question:
- 16.
A ___________ consists of all the different alleles present in a population
Correct Answer
gene poolExplanation
A gene pool refers to the collection of all the different alleles present in a population. It represents the total genetic diversity within a population and includes all the variations of genes that can be passed on to the next generation. The gene pool is crucial for understanding genetic variation and evolutionary processes within a population.Rate this question:
- 17.
Which of the following is NOT part of Darwin's theory of evolution?
- A.
Organisms in a population show a natural variation in heritable traits.
- B.
Organisms must compete for resources because organisms produce more offspring than can survive
- C.
Species alive today are descended with modification from ancestral species that lived in the distant past
- D.
Evolution unites all organisms into a single tree of life
- E.
Acquired traits can be inherited
Correct Answer
E. Acquired traits can be inheritedExplanation
Darwin's theory of evolution states that organisms in a population show a natural variation in heritable traits, organisms must compete for resources because they produce more offspring than can survive, species alive today are descended with modification from ancestral species that lived in the distant past, and evolution unites all organisms into a single tree of life. However, acquired traits cannot be inherited according to Darwin's theory. This means that traits acquired during an organism's lifetime through individual effort or experience cannot be passed on to the next generation.Rate this question:

_________ organs are reduced in size and no longer function
Correct Answer
vestigialExplanation
Vestigial organs are reduced in size and no longer function. These organs are remnants of structures that had a function in the evolutionary ancestors of the organism but have lost their original purpose over time. They serve no significant function in the current organism, and their small size and lack of functionality are evidence of their vestigial nature.Rate this question:

Name the kind of macroevolution in which populations show a pattern of long stable periods interrupted by brief periods of rapid change.
- A.
Gradualism
- B.
Punctuated Equilibrium
- C.
Divergent Evolution
- D.
Convergent Evolution
Correct Answer
B. Punctuated EquilibriumExplanation
Punctuated equilibrium is a concept in evolutionary biology that describes a pattern of evolution in which populations experience long periods of stability (stasis) interrupted by brief periods of rapid change. This contrasts with gradualism, which suggests that evolution occurs at a slow and steady pace. Punctuated equilibrium helps explain the relatively abrupt appearance of new species in the fossil record, followed by long periods where species show little evolutionary change.Rate this question:

A situation in which allele frequencies change as a result of the migration of a small subgroup of the population is known as the
- A.
Bottleneck Effect
- B.
Founder Effect
- C.
Genetic Drift
- D.
Natural Selection
Correct Answer
B. Founder EffectExplanation
The founder effect occurs when a small subgroup of a population migrates and establishes a new population in a new location. This small group's gene pool may not be representative of the original population's gene pool, leading to changes in allele frequencies in the new population. Over time, these changes can result in significant genetic differences between the new population and the original one. The founder effect is a type of genetic drift, where random changes in allele frequencies occur in small populations.Rate this question:

Name the two scientists who came up with a mathematical equation to express the frequencies of alleles in a population
- A.
Charles Darwin and Alfred Wallace
- B.
Gregor Mendel and Thomas Hunt Morgan
- C.
Godfrey Hardy and Wilhelm Weinberg
- D.
James Watson and Francis Crick
Correct Answer
C. Godfrey Hardy and Wilhelm WeinbergExplanation
Godfrey Hardy and Wilhelm Weinberg are the two scientists who independently formulated the Hardy-Weinberg principle. This principle provides a mathematical equation that describes the genetic equilibrium within a population. It states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. The equation p^2 + 2pq + q^2 = 1 is used to calculate the expected frequencies of genotypes based on allele frequencies, where ppp and qqq represent the frequencies of two alleles.Rate this question:

Name the naturalist whose ideas about evolution were similar to Darwin's and who prompted Darwin to publish his book "On the Origin of Species"
- A.
Jean-Baptiste Lamarck
- B.
Alfred Russel Wallace
- C.
Thomas Huxley
- D.
Ernst Haeckel
Correct Answer
B. Alfred Russel WallaceExplanation
Alfred Russel Wallace was a naturalist who independently developed a theory of evolution through natural selection that was strikingly similar to Charles Darwin's ideas. Wallace's manuscript, which he sent to Darwin in 1858, prompted Darwin to publish his own work, leading to the joint presentation of their findings to the Linnean Society of London. This collaboration and the subsequent publication of Darwin's book "On the Origin of Species" in 1859 marked a significant milestone in the acceptance and understanding of evolutionary biology.Rate this question:

Another name for divergent evolution is
- A.
Adaptive Radiation
- B.
Convergent Evolution
- C.
Parallel Evolution
- D.
Coevolution
Correct Answer
A. Adaptive RadiationExplanation
Another name for divergent evolution is adaptive radiation. Divergent evolution occurs when two or more species sharing a common ancestor become more different over time, often due to different environmental pressures or ecological niches. Adaptive radiation is a type of divergent evolution where a single ancestral species rapidly diversifies into a multitude of new forms to exploit different ecological niches. This process is often seen in island ecosystems, where species adapt to a variety of unique habitats.Rate this question:
